Ribosomes<span> are usually found in the rough endoplasmic reticulum, but can also be found throughout the cytoplasm.</span>The job of the ribosome is to make new proteins. If all of a cells ribosomes were weakened, the cell would be unable to make new proteins.
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>
I would say that t<span>he foremost purpose of a human community is to meet human needs by working together. </span>
Some afferent neurons are sec specialized to detect stimuli, whereas efferent neurons send signals to the effectors of the nervous system.
