They intersect and cross each other
Answer:
Letter E - exons are cut from the strand and removed
Explanation:
Letter A and B are incorrect because the poly-A tail and guanine cap are added to the 3’ and 5’ end respectively. They aid in translation of the mRNA, while serving as protection. The poly-A tail is repeated adenine nucleotides, while the guanine cap is a modified guanine nucleotide.
Letter C is incorrect because alternative splicing is one mechanism for generating variation, and is thought to be one of the reasons for why humans have smaller genomes than other organisms and still maintain high complexity. Alternative splicing is incredibly important because it produces more than one transcript from a pre-mRNA.
Letter D is incorrect because introns are the non coding portions of the mRNA. They are excised to make a smaller mRNA transcript, and one that contains all the protein genes.
This letter E is the correct answer, because exons are the coding portions of the mRNA, and are not excised during RNA processing.
Hope that helped! If I made a mistake, please let me know.
Two identical cell because the main purpose of the cell cycle is to make two identical cell.
Answer:
peripheral circulation is decreased
Explanation:
Systemic circulation, also called large circulation, transports blood to all tissues of the body. In addition, it also ensures the nutrition of the vessels that constitute the small circulation, or pulmonary circulation. It is called large circulation or peripheral circulation. When this circulation is slowed there is a delay in the time to recharge hair, which must occur simultaneously.
The infant in question is experiencing a delay in capillary recharge time, so we can conclude that the baby's peripheral circulation is decreased
