Biology EOC Review DNA to Proteins

What is the result of this process?

• an increase in offspring variation.

• the deletion of amino acid sequences.

• an increase in mutations in genetic material.

• the production of gametes that are genetically identical.

Which statement describes evidence that supports your choice in the previous question?

• Offpring genotypes are determined by gametes.

• Offspring genotypes are determined by both somatic cells and gametes.

• Independent assortment of alleles in somatic cells causes mutated genes to be passed on to offspring.

• Mutations in somatic cells are highly inheritable because they transport nutrients throughout the organism.

A mutation occurs in the DNA base sequence GGG GAG TTA resulting in the base sequence GGA GAG TTA. Use the information in the table to determine the effects of this mutation on the amino acid chain produced.

• Proline is now lysine and leucine is unchanged.

• Proline is now lysine and asparagine is unchanged.

• Proline is unchanged and asparagine is unchanged.

• Proline is unchanged and leucine is now phenylalanine.
