A mitotic cdk-cyclin complex triggers entry into mitosis.
<span>
Cdk-cyclin complex consists of two units: cdk which is a cyclin-dependent kinase (catalytic subunit) and cyclin (regulatory subunit). This complex play a crucial role in cell cycle progression. There are different types of cdk-cyclin complex, for example, Cdk1-cyclin B1 complex triggers entry into mitosis (progresses the cell cycle through G2/M mitotic phase).</span>
A genetic change that occurs due to the evolutionary process, which consists of modifications in the structure or attributes of an organism, is a mutation.
Mutation is one of the evolutionary processes (fundamental forces of evolution) that together with natural Selection, genetic drift and gene flow can change allele frequencies within a single population. Mutations are the only way to form new alleles in a gene pool.
Tt - because heterozygous means [different] so it’s 2 different letters
