Nucleic Acid and Gene Expression

Albumin is a protein that is secreted by liver cells and transported to the bloodstream. What factor most directly determines the amino acids that are combined to create albumin?

• The temperature of the cell when translation is taking place

• The number of chromosomes in a cell

• The sequence of nucleotides in DNA

• The amount of energy that is available in the cell

Why are insertion and deletion (frameshift) mutations so harmful?

• They change all of the codons from the mutation on down the line, which changes the amino acid sequence

• They insert things that an organism doesn't need.

• They often delete things that organisms need.

• Insertion and deletions are not any more harmful than substitution mutations.
