Question

What kind of mutation is present in the strain's ura3 gene? MATa ura3-delta2 leu2 his3::URA3

Answer 1

Step-by-step explanation:

What is the function of URA3?

URA3 encodes orotidine 5-phosphate decarboxylase (ODCase), an enzyme involved in the de novo synthesis of pyrimidine ribonucleotides (shown here; 2). ODCase, which is responsible for catalyzing the decarboxylation of orotidine 5-phosphate (OMP) to uridylic acid (UMP), is one of the most proficient enzymes in nature.
