Explanation:

Individuals can be identified by comparing the length of STR regions on a gel because these regions vary in length between individuals and can be used for human identification, while it is not possible to identify individuals by comparing the length of genes on a gel because genes are functional units of DNA that do not vary significantly between individuals.

Short Tandem Repeats (STRs) are DNA sequences that vary in length between individuals and are used for human identification. STR profiling is a technique that compares the number of repeats in certain regions of DNA between different individuals.

It is a useful tool in forensic science for identifying individuals in a criminal investigation or determining relationships between individuals.

The length of STR regions is analyzed using a technique known as gel electrophoresis, which separates DNA fragments based on their size.

Answer : Plants play an important role in the discovery of new drugs and many blockbuster drugs are derived either directly or indirectly from plants. It's important that we protect biodiversity of plants so that new drug discoveries can be made in the future. This has a huge impact on health and is also an economic benefit.

Explanation:

Without plants there would be no food. All carbon in proteins, fats and carbohydrates is derived from photosynthesis in plants. Everything we eat, including meat from animals (which feed on plants) is a result of plants using the energy in sunlight to take carbon dioxide and create complex carbon-containing molecules.

Protecting our native plants and trees is vital. They are the ecological basis upon which wildlife depends. Native plants support significantly more wildlife than non-native species. They are adapted to the local climate, soil type and wildlife and without them, native wildlife would not be sustained.

Having a diverse and rich variety of plants is not only socially and environmentally important - they also have great economic benefits through farming and tourism. Plants are vital for life.

Selection is the most effective factor in changing the allele frequency in a natural population. So, option E is accurate

Selection refers to the process by which certain traits or alleles are favored or disadvantaged in a population, leading to differential reproductive success. When certain alleles confer an advantage in terms of survival or reproductive success, they are more likely to be passed on to future generations, resulting in an increase in their frequency. Conversely, alleles that are less advantageous are more likely to be lost from the population over time.

While other factors such as population size, mutation rate, migration, and mating patterns can also influence allele frequencies to some extent, selection is the primary driver of evolutionary change. It acts as a powerful force in shaping the genetic makeup of a population by favoring advantageous alleles and driving changes in allele frequencies over generations.

Mitochondria and chloroplasts are the other organelles besides the nucleus that contain DNA.

This is also called deoxyribonucleic acid and is known as the genetic material of living organisms. DNA is responsible for the passing of different types of traits from parent to offspring.

DNA is present in organelles such as mitochondria and chloroplasts as they are involved in the different types of growth and reproductive processes which occurs in the cells of organisms. It is also present in the nucleus of cells because it controls and regulates the metabolic activities which occur in the cell.

A protein recognizes the stop codon, and the ribosome dissociates from the mRNA during eukaryotic translation termination.

In the eukaryotic interpretation end, the ribosome perceives a stop codon in the mRNA, and a protein called a delivery factor perceives the stop codon.

The ribosome then, at that point, separates from the mRNA, delivering the recently incorporated polypeptide chain.

This cycle is pivotal in deciding the right length and grouping of the polypeptide chain, as any blunders in interpretation end could bring about the creation of non-practical or possibly hurtful proteins.

A homozygous mutation will result in the complete absence of LDL receptors on hepatocytes, increasing the LDL cholesterol levels. The correct answer is option (A).

Very low-density lipoprotein (VLDL) is produced by the liver and converted to IDL by lipoprotein lipase (LPL). By means of hepatic triglyceride lipase, IDL gets changed into LDL (HTGL). Hypercholesterolemia, also referred to as familial hypercholesterolemia, is an autosomal dominant illness that can be brought on by defects in LDL receptor function. Because the binding and subsequent uptake of LDL molecules in the blood depends on LDL receptors on the surface of hepatocytes, a hereditary decrease in LDL receptor number would result in a lower ability of hepatocytes to absorb LDL and increase LDL in the blood. LDL is typically around 300 mg/dL, but if this mutation is heterozygous, some LDL receptors will be present in the hepatocytes. The LDL cholesterol levels will rise to 1000 mg/dL due to the complete absence of LDL receptors on hepatocytes as a result of a homozygous mutation, though.

The complete question is:

What type(s) of mutation(s) would result in the inability of an individual’s cells to take up LDL from the bloodstream?

(A). Mutations could occur in the receptor itself to preclude LDL binding.

(B). Mutations could occur in proteins that position the LDL receptor on the plasma membrane.

(C). Mutations could occur in the protein machinery that allows the LDL particle to enter the cell.

(D). Mutations could occur in the protein component of LDL that recognizes the receptor.

Placentals and marsupials came from a common ancestor which was Theria . It seems reasonable to say that the common ancestor was more similar to modern marsupials than they are to modern placentals.

Placentals seemed to outcompete most marsupials everywhere they existed. Australia has basically all marsupials because the placentals never existed there until humans brought them.

Explanation:

In comparison , Cas9 is an endonuclease and is developed as an immunity mechanism against viruses, which  are not considered restriction enzymes.

Talking about the similariites and differences, endonuclease is an enzyme by cleaving the internal covalent bonds linking nucleotides to break down a nucleotide chain into shorter chains, whereas the restriction enzyme, considered the restriction endonuclease can cleave DNA molecules into small pieces. Cas9 is an endo-deoxyribonuclease, it trims the DNA a little bit, from the cut site, one of the differences is that to identify the target sites in the DNA restriction enzymes doesn't have an RNA or a DNA as a tether. They can recognize the restriction sites by themselves through their DNA binding domains. Compare to restriction enzymes, the endonuclease can't cleave any DNA complementary to the guide RNA, they need the help of protospacer adjacent motifs adjacent sequences to the target site. The cleaving process occurs at a specific site called the restriction site, of the  DNA molecule,  where the site is composed of  4 to 8 base pairs. The restriction enzyme is all about all in one system whereas the endonuclease enzyme recognizes first and cleaves the latter, within a  specific nucleotide sequence.

Most of the metabolic activity happens within the cytoplasm of a cell.

Metabolic activity refers to the various processes conducted inside the cell in order to synthesize energy. The metabolic activities are of two types: anabolic and catabolic. Anabolic activities are the ones that form large compounds by combining the smaller ones, while catabolic ones are the opposite.

Cytoplasm is the gel-like liquid material present inside the cell. It is composed of the fluid of the cell and the cell organelles. Fluid present inside the nucleus is excluded from the cytoplasm. The cytoplasm provides the medium where various activities can take place and cell organelles can perform their respective functions.

The renal sinus is a sizable cavity inside the kidney that is reached via the hilum. The renal artery enters the kidney at the hilum, and the ureter and renal vein exit the kidney. The renal cortex is the outer, reddish area next to the capsule. The renal medulla, a darker reddish-brown area, is surrounded by this.

The kidney's concave hilum is where blood vessels, nerves, and the ureters leave the bean-shaped organ. Arcuate arteries give rise to interlobular arteries, which then ascend into the cortex and split into afferent arterioles that supply blood to the glomerular capillaries. The glomerular capillaries reorganize into the efferent arterioles, a second arteriolar network, after passing through the renal corpuscle.
