The correct answer is: B) -20 kcal/mol
Enzymes are catalysts of chemical reactions, they speed up the reaction by lowering the activation energy, but don't affect the ∆G (change of Gibbs free energy). The changes in free energy occurs due to change in concentrations of reactants and products and don't have anything to do with the presence or absence of an enzyme.
The best way to explain the discrepancy between the normal length of prolactin (199 amino acids) and the length of the polypeptide synthesized in the experiment (227 amino acids) is that in the absence of Signal Recognition Particle (SRP) and the Endoplasmic Reticulum membrane,a prolactin precursor molecule is therefore synthesized.
Prolactin also plays a role in the stimulation of the proliferation of oligodendrocyte precursor cells.
Relating to all, The Signal Recognition Particle plays a crucial role in mediating the transport of secretory and membrane protein to the Endoplasmic Reticulum or plasma membrane.
This can occur both in the prokaryotic or eukaryotic cell.
Answer:
By changing a gene's instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all.
Explanation:
<span>A virus is made up of a core of genetic material, either DNA or RNA, surrounded by a protective coat called a capsid which is made up of protein. Sometimes the capsid is surrounded by an additional spikey coat called the envelope. Viruses are capable of latching onto host cells and getting inside them.</span>
Answer:
cells arise from preexisting cells
