Answer:
Clumped
Explanation:
Beaver with the Botanical name Castor canadensis is a species that affects
the structure of an habitat and its dynamics this is done by the diverting of streams, and the felling of trees and other woody vegetation.
They usually live in colonies i.e clumped together in a particular area not individually and a colony can support 2–14 beavers that are related and on the average Six Beavers.
They are about 35–40 inches long and
Weighs 30–60 pounds. The average lifespan of a beaver is 5 years and are active both in the morning and at night.
I think it could be letter B maybe I may be wrong I’m a beginner
Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

What is DNA molecule?</h3>
- Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
- Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
- An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
- To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.

Answer:
mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
