Answer:
The correct answer is option c, that is, alternative splicing.
Explanation:
When a solitary pre-mRNA molecule is processed in two or more than two ways to produce two or more RNA it is known as alternative splicing. This distinct RNA post-translation produces different products of genes. It takes place when one 5 prime splice site of the intron is associated with more than one 3 prime splice sites and is possibly mediated by the structural conformation of RNA and some of the splicing regulators, like SR protein.
The alternative splicing takes place distinctly in different cell types and is also monitored by the cell type-specific factor. The remaining of the options are not correct as these options are related to the process control mechanism.
Answer:
The correct answer is arteries.
Explanation:
The ventricles refer to the lower two chambers of the heart. The prime function of the ventricles is to pump blood to the rest parts of the body. Arteries refer to the vessels, which will be the first one to come in contact with the blood from the ventricles.
Arteries are the blood vessels, which mediate blood away from the heart to the other parts of the body like tissues and lungs. The arteries are strong, thick, and exhibit elastic walls. The distinct types of arteries comprise elastic arteries, muscular arteries, and arterioles.
Answer: 47 Chromosomes
Explanation: People with Down syndrome typically have three copies of chromosome 21 in each cell, for a total of 47 chromosomes per cell.
Answer: It is a complex, folded chain that helps regulate cell processes". The monomers of a protein are amino acids. Many amino acids form a long linear chain to become peptides which is the primary structure of a protein molecule.
