Answer:
ubiquitin targets CDKs
Explanation:
Cyclins are named such because they undergo a constant cycle of synthesis and degradation during cell division. When cyclins are synthesized, they act as an activating protein and bind to Cdks forming a cyclin-Cdk complex. This complex then acts as a signal to the cell to pass to the next cell cycle phase.
Cyclins drive the events of the cell cycle by partnering with a family of enzymes called the cyclin-dependent kinases (Cdks). A lone Cdk is inactive, but the binding of a cyclin activates it, making it a functional enzyme and allowing it to modify target proteins.
I think it’s phenotype bc phenotypes is what the natural selection acts on bc it’s what interacts with an organisms environment and not the genotype.
The correct answer should be The ability to reproduce only within a species.
A single insertion or deletion of a nucleotide will basically lead to a frameshift mutation where the “reading frame” is disrupted. Normally, amino acids are encoded by three nucleotides, called a codon.
