Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.
<h3>
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: D. Frameshift mutation
Explanation:
A nonsense mutation is one in which a codon codifying for an amino acid is replaced by a stop codon, resulting in a premature end to translation (e.g. TAT [Tyrosine] >> TAG [stop]).
A missense mutation is one in which a codon is altered in such a way that it ends up codifying for a <em>different</em> amino acid (e.g. AUA [Isoleucine] >> AUG [Methionine]).
A point mutation is any mutation which involves the altering of a single nucleotide (such as the examples given above), <em>regardless</em> of its effect on the resulting protein.
Finally: a frameshift mutation is one which alters the <em>reading frame</em> of a gene, which results in a whole different set of nucleotides being treated as individual codons by the translation machinery. The consequence of this is a significant change in the resulting amino acid sequence. Frameshift mutations may be the result of several mechanisms which include insertions and deletions. The example given in the picture appears to show an example of one such mutation.
Answer:Major functions of connective tissue include: 1) binding and supporting, 2) protecting, 3) insulating, 4) storing reserve fuel, and 5) transporting substances within the body. Connective tissues can have various levels of vascularity. Cartilage is avascular, while dense connective tissue is poorly vascularized.

Answer:
carbon dioxide
The process of photosynthesis is often described as turning sunlight into sugars
I only know one for the first one, don't be mad, please.
1. I'm pretty sure one of them is membrane
2. A cell can die through infection, poisoning, overheating, or even lack of oxygen.
3. I think it depends on how fragile the membrane of the cell is.
I'm so so so sorry if these didn't help, I'm trying my best, lol.
