a portion of a specific DNA molecule consists of the following sequence of nucleotide triplets?
TAC GAA CTT GGG TCC
this DNA sequence codes for the following short polypeptide
describe the steps in the synthesis of this polypeptide. what would be the effect of a deletion or addition in one of the DNA nucleotides? what would be the effect of a substitution in on of the nucleotides?

No it doesn't. Extremely bad question. To fix the question you would need to specify that this DNA strand is written 3' end first, and further specify that this is the "transcribed strand." Bonk your teacher with a clue bat. Directionality is important. To emphasize this, hold the clue bat by the grip end and bonk your teacher with the other end.

a) 1.- get the RNA sequence of each.
2.- get its anticodon.
b) all the amino acids following the deleted or added nucleotide will change.
c) the mutation can vary depending the location of the substitution; if it was the last nucleotide it can still make the same amino acid, but if it was the first it will entirely change the amino acid.Source(s): Miller & Levine, Biology
