Cyclins
are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing
of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent
kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other
molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk
complex. This complex then functions by acting as a signal to the cell to move
to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk
is deactivated, therefore signaling exit from a specific phase.</span>
Stem cells because they are compatible of dividing and renewing themselves after long periods
Answer:
The characteristics of allosteric enzymes are listed below.
Explanation:
1 They may have binding sites for regulatory molecules that are separate from the active site.
2 They tend to have sigmoidal curve of V0 vs [S].
3 They undergo conformational change as a result of modulator binding
Explanation:
Mosses go through sporophyte and gametophyte stages in their life cycle. ... However, mosses are nonvascular while ferns are vascular. Gymnosperms and angiosperms are both vascular, seed-bearing plants. However, gymnosperms release their seeds in cones (like pinecones) while angiosperms release their seeds through flowers.
This isn't always the case and there is no reason it should be .Whether or not a trait is common has to do with how many copies of that gene version (or allele) are in the population. It has little or nothing to do with whether the trait is dominant or recessive. Let's take eye color as an example.
