The yeast gene encoding a protein found in the mitotic spindle was cloned by a laboratory studying mitosis. the gene encodes a protein of 477 amino acids. a. what is the minimum length in nucleotides of the protein-coding part of this yeast gene? b. a partial sequence of one dna strand in an exon containing the middle of the coding region of the yeast gene is given here. what is the sequence of nucleotides of the mrna in this region of the gene? show the 5' and 3' directionality of your strand. 5' 3' c. what is the sequence of amino acids in this part of the yeast mitotic spindle protein?
