zimovet [89]

Answer: Bacteria lack a mechanism for splicing out introns

Explanation:

Factor VII gene is 186k nucleotides long while the protein is 2332 amino acids long. <u>This lenght discrepancy is due to introns interrupting gene</u>, because the cell first transcribes the entire gene and then cuts introns out of the transcript. At the end, it splices the remaining pieces. Prokaryotes don't perform splicing so it can not edit out introns from the primary mRNA transcript. To produce an eukaryote gene in prokaryotes it is necessary to use a reverse transcriptase to get a cDNA sequence without the introns, and then insert that into a bacterial genome.

Sav [38]

when changes in a protein appear to accumulate at a constant rate over time is called option (c) i.e, Molecular clock.

<h3>What does molecular clock mean?</h3>

The term "molecular clock" refers to a method that estimates the time in prehistory when two or more life forms diverged by analyzing the mutation rate of biomolecules. Typically, nucleotide sequences for DNA, RNA, or amino acid sequences for proteins serve as the biomolecular data for these calculations.

Hedges, a biology professor at Penn State, claims that the molecular clock counts the mutations that accumulate through time in the gene sequences of various species rather than counting seconds, minutes, and hours.

Mutation and recombination, the two fundamental biological processes that give rise to all heritable variations, are the foundation of molecular clocks. Mutations are modifications to the genetic code of DNA, for as when the nucleotide Guanine (G) turns to Thymine (T).

Why are plants like grasse able to
timurjin [86]

Answer:

C.) The root may grow horizontal rhizomes that make new shoots.

Explanation:

Plants like grasses able to  reproduce more quickly than others because their roots grow horizontal rhizomes into a new shoots. These grasses spreads in the soil due to movement of rhizomes horizontally and grows its shoot with this movement. This spreading helps the grasses to make carpets in the grounds and has the ability to grow faster than other plants so we can say that growth of horizontal rhizomes is responsible for quick growth of grasses.
