A gene can be mutated with no resulting functional change in the protein that is produced from that gene if
1. RNA polymerase can edit the mutation from the mRNA produced during translation
2. The mutation alters the active site of an enzyme
3. The entire codon has been removed
4. A codon has changed, but it codes for the same amino acid as the original codon

The genetic code is degenerate, meaning that a codon can specify more than one ... A DNA sequence produces a mutant protein in which several amino acids in the ... Transcription initiation occurs when RNA polymerase binds to a complex of ... a.C-terminal domain (1), N-terminal domain 1 (2), N-terminal domain 2 (3) b.

Explanation:

the major parts of the digestive system:

salivary glands.

pharynx.

esophagus.

stomach.

small intestine.

large intestine.

rectum.

accessory digestive organs: liver, gallbladder, pancreas.

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
