Varieties of plants in which self-fertilization produces offspring that are identical to the parents are referred to as true-breeding. In this process the parents will pass down specific phenotypic trait of their offspring. True bred organisms will have pure genotype (genetic make up of an organism) and will therefore produce certain phenotype.
I believe the answer is c
Answer:
Cyclin dependent kinase 1 or CDK 1 is a catalytic protein whose action is regulated by cyclin B.
Explanation:
CyclinB-CDK 1 complex is also termed as maturation promoting factor that helps in the entry of the cell into the M phase.The concentration of Cyclin B -CDK1 rises by various process such as dephosphorylation and falls by the degradation of cyclin B.
The cyclinB-CDK 1 is inactivated by phosphorylation of at tyr 15 residue.cyclinB-CDK1 interacts with various proteins such as survivin,which is essential for spindle formation that in turn regulate the cell viability.
