N the early 1900's a scientist hypothesized a link between DNA and the production of proteins in the cytoplasm. However, the fac
t that DNA could not be found outside the nucleus led scientists to belive that another substance was also involved in the synthesis of protein in the cytoplasm. In the 1940s scientists performed an experiement that ultimately identified the site of protein synthesis. They also identified the molecule respnsible for transporting information from the nucleus to the site of protein synthesis. What was this newly identified molecule? Your answer:
How does the cytoplasm synthesize protein?
How does DNA replicate in the cytoplasm to make genes?
What molecule transports information from the nucleus to the cytoplasm to make protein?
How does thymine work?
The plasma membrane or the cell
membrane is the one that protects the cytoplasm of a cell. It is mostly
composed of lipids and proteins. It has a phospholipid bilayer that controls
the entering and exiting of molecules in the cell and at the same time,
provides protection for the cell or plasma membrane. It has polar head and a
nonpolar tail. Proteins embedded within the phospholipid bilayer have the same
function of the plasma membrane that includes selective transport. The
phospholipid bilayer consists mainly of the lipid molecules.
