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.
I see there should be an options to choose. Anyway I know the answer. Synaptic pruning refers to the <span>the downsizing of neuronal connections </span>that helps strengthen connection between neurons.
Does it have answer choices
A. Geologist → rocks around and under the hot spring
B. ecologist → relationships between organisms and the hot spring
C. sociologist → human behavior around the hot spring
D. meteorologist → atmosphere and weather around the hot spring
Meiosis takes place in reproductive cells, whereas mitosis happens in somatic cells.
<h3>What is Mitosis ?</h3>
A single cell divides into two identical daughter cells during the process of mitosis.
<h3>What is Meiosis ?</h3>
A single cell splits twice during the meiosis , resulting in four cells with half the original genetic material.
<h3>What makes mitosis and meiosis distinct from one another?</h3>
- In contrast to mitosis, which results in 2 daughter cells at the end of cell division, meiosis results in 4 daughter cells.
- Meiosis results in the creation of four daughters with half of their parents' DNA as opposed to mitosis' two genetically identical daughter cells.
- Meiosis produces haploid cells, while mitosis creates diploid cells.
