What mRNA sequence would be transcribed from the following nucleotide sequence?

Question

and what amino acid sequence would result???
The sequence is:
CTTTTCGGTCAT.

Also if there was an error in changing the first base of the DNA sequence from C to T, how would this affect the amino acid sequence?

Answer 1

actually, from this sequence no amino acid sequense would result. for a sequence to be tranlated, it has to have the starter sequence AUG (which would be TAC in dna), which also codes for Methione.

Also, remember that mRNA is only read in the 5'-->3' direction. And also remember that mRNA will be transribed antiparallel to the DNA strand. make sure that the nucleotide sequence is being written in teh right direction.

Also, the convential way of writing a DNA sequence is from the non-template strand, so you'll have to make sure that's the right strand.

now of course, if this is just a high school bio assignment, then the answer you're looking for is yes glu-lys-pro-leu

Answer 2

The amino acid sequence that would result is :

GAAAAGCCAGUA

if it changed from a C to a T then it would be a totally different amino acid sequence!

Answer 3

The mRNA would be GAA AAG CCA CUA

The protein would be glu-lys-pro-leu

If the first base was a T, then the mRNA would start with an A, and the first amino acid would be lysine.
