Question

1. the assembly of a messenger rna strand that normally begins with uac has been changed so that the newly assembled messenger rna strand begins with uag. which of the following will most likely occur?

a the protein will be missing the first amino acid.
b the amino acids that make up the protein will all be different.
c the mrna will become attached to a ribosome.
d the production of the protein will be stopped.

1. which molecule is most responsible for determining an organism’s eye color, body structure, and cellular enzyme production?

a complex starch
b fatty acid
c carbohydrate
d deoxyribonucleic acid

Explanation:

1. In the codon chart, UAG is a stop codon. When it appears at the start instead of a start - codon (like AUG which is often the start, and UAC is not a start codon but UAG being a stop codon will halt translation immediately.
2. DNA (Deoxyribonucleic acid) contains the genetic information that determines an organism's traits such as eye color, body structure, and codes for the production of cellular enzymes.

Answer:

1. D. The production of the protein will be stopped.
2. D. Deoxyribonucleic acid
