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.

The correct answer is option B, that is, Genetic drift greatly affects small populations, but large populations can recover.
Genetic drift in combination with mutation, natural selection, and migration is one of the most fundamental mechanisms of evolution. Genetic drift refers to a change in the relative frequency of distinct genotypes in a small populace, owing to the chance vanishing of specific genes as individuals do not reproduce or die.
Answer:
Well, it’s because tattoos have to get that ink deep enough that it won’t get washed away but not too deep so it remains visible — the ideal location ends up being right next to your skin’s pain receptors.
Sweat glands and sebaceous glands are exocrine glands. Pineal and adrenal glands are endocrine glands.
