During the gene expression process, what happens to the DNA?

• The DNA is replicated to make more DNA.

• The DNA is transcribed into RNA, which is then translated into protein.

• The DNA is broken down into nucleotides.

• The DNA leaves the nucleus to be expressed in the cytoplasm.

What are the parts of a nucleotide?

• 3 parts: a sugar, a phosphate molecule and a base (A, G, C, T)

• 2 parts: a sugar and a base (A, G, C, T)

• 4 parts: a sugar, a phosphate, a base, and a lipid

• 3 parts: a sugar, a protein, and a base (A, G, C, T)

On a DNA strand: where are the weak bonds located, and where are the strong bonds located?

• The weak bonds are located on the inside, connecting the bases. The strong bongs are on the outside connecting the sugar and phosphate

• The weak bonds are located on the outside, connecting the sugar and phosphate.

• The weak bonds are located between the phosphate groups only.

• The weak bonds are located on the backbone, connecting the sugars.
