What would be first three amino acids in the protein formed from this gene? utc gtu ttg

The three amino acid will be Tyrosine, Asparagine and Lysine respectively to sequence.

UTC GTU TTG

First the thymine in the sequence is changed to A, adenine because in the mRNA only three types of nucleotides are allowed which are Adenine, thymine and Uracil.

So the sequence will be:

UAC GAU AAG

These codons will be read by tRNA producing the polypeptide sequence of amino acids which are as follow:

Tyrosine Asparagine Lysine.

after making a punnet square using bv bv bv bv you will find that the ratio will be 9: 7 or a 128.6% probability.

hope this
