Question

The following sequence is a fragment from exon 4 of the normal TRYP1 gene from sheep: 5'-ATG GTT GTA TGC GAA AGT CTA-3'.

A transversion mutation in the sequence results in a change in the 4th amino acid of the polypeptide chain: a Phenyalanine is produced. The DNA sequence with the mutation is ____

The template strand of the normal TRYP1 fragment is _____________

When the normal gene is transcribed the result is the mRNA____________.  

The protein encoded by the normal TRYP1 gene is ___________

A transversion mutation in the sequence results in a change in the 4th amino acid of the polypeptide chain to produce the amino acid Phenyalanine. When this mutated sequence is

The light coloured sheep have this fragment 3'- TAC CAA CAT AAG CTT TCA GAT -5'. When the gene is transcribed what polypeptide results?

5'- AUG GUU GUA UUC GAA AGU CUA -3'

Methionine-Valine-Valine-Phenylalanine-Glutamic acid-Serine-Leucine

5'- AUG GUU GUA UGC GAA AGU CUA

3'- TAC CAA CAT ACG CTT TCA GAT- 5'

Methionine-Valine-Valine-Cysteine-Glutamic acid- Serine-Leucine

5'-ATG GTT GTA TTC GAA AGT CTA-3'.

Match the answers please.
