Question

Professor snuck this in on my home work. We haven’t gone over it in lab nor lecture. Nothing in the study guides either. Help!

Answer 1

Asn-Gly-Try-Ser-Arg

Step-by-step explanation

Step 1: Know which DNA strand is given. There are two strands: Coding strand or non-coding strand, in this case we are given a non-coding strand sequence:

3'-AAT GGC TAA TCT AGA-5'

STEP 2: Write the corresponding m-RNA strand.

Using non-coding strand: (T=U) Read from left to right

5'-AAU GGC UAA UCU AGA-3'

STEP 3: Convert m-RNA as a sequence of codons. ALWAYS start from the codon AUG and NEVER count the same nucleotide twice!

AAU GGC UAA UCU AGA

Step 4: Use the given table to find the relevant amino acid sequence.

Answer

Asn-Gly-Try-Ser-Arg
