Answer:
How does a bacterial cell protect its own DNA from restriction enzymes?
B. by adding methyl groups to adenines and cytosines
Explanation:
The restriction modification system is for the cells defense mechanism. This system is composed of a restriction endonuclease enzyme and a methylase enzyme and each bacterial species and strain has their own combination of restriction and methylating enzymes.
Bacteria have restriction enzymes, also called restriction endonucleases, which cut double stranded DNA at specific points into fragments. This restriction enzymes don’t cleave the bacteria's own DNA because restriction enzymes do not exist in the bacterial DNA sequence.
But is if the recognition sequences exist but the enzyme is methylation specific. Bacteria prevent their own DNA from chop down by restriction enzyme through methylation of the restriction sites. Methylation of DNA is a very familiar way to modify DNA function and bacterial DNA is highly methylated.
Answer:
TAAC
Explanation:
A binds to T, T binds to A, and G binds to C. If the other chain is an mRNA chain, it will be UAAC.
The sexual type of reproduction requires cells to undergo the process of meiosis however the other type which is asexual only mitosis is important to reproduce. In meiosis, a cell is being separated into two unique cells while mitosis reproduce where all cells are identical.
