B. All of the cell's DNA attaches to proteins.
C. RNA attaches to DNA
D. The DNA folds over on itself to create a dense chromosome.

Answers

Answer 1
Answer:

In DNA replication, the DNA unravels to make two strands.

What do you mean by DNA replication?

DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the most essential part for biological inheritance.

DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides.

Cells must replicate their DNA before they can divide. This ensures that each daughter cell gets a copy of the genome, and therefore, successful inheritance of genetic traits.

How is the frog skin different from human skin

Answers

Frog skin has like slimy stuff on the outside
Frog skin is the way frogs exchange a lot of materials with their environment. It is very permeable. Many frogs don't drink because they can absorb / excrete water through their skin.

Human skin is not easily permeable. It is a barrier that protects us. It can't absorb water. It has sweat pores that excrete water to cool you off. It is continously shedding dead cells and replenishing them with new ones. Melanin darkens your skin to protect from sun exposure. 

In dna which nucleotide does adenine bond with

Answers

The answer is thymine.

The base unit of DNA is called a nucleotide. The nucleotide consists of a nucleobase (adenine - A, thymine - T, cytosine - C, and guanine -G), a monosaccharide deoxyribose, and a phosphate group. Two nucleotides of the different strands are joined by hydrogen bonds. According to the base pairing rules, adenine pairs with thymine (A-T), and cytosine pairs with guanine (C-G).
