Question

Transcribe the following DNA sequence into mRNA, and then translate it into protein. Be sure to figure out where translation would start, and where it would stop.

DNA     GGCTATACCGGTTACCGATAATTGGCTATCTG

RNA:

Protein:

Answer 1

DNA

5' - GGC TAT ACC GGT TAC CGA TAA TTG GCT ATC TG - 3'

3' - CCG ATA TGG CCA ATG GCT ATT AAC CGA TAG AC - 5'

mRNA will be formed after transcription of template strand (3' to 5' strand),

5' - GGC UAU ACC GGU UAC CGA UAA UUG GCT AUC UG - 3'

Amino acids will be formed after translation of mRNA,

N - gly tyr thr gly tyr arg STOP - C

Use genetic code table to find out the sequence of amino acids.

There is no start codon (AUG) in the given sequence. So, we will assume this sequence to be a part of a long peptide and translate the sequence.
