When the cell needs to produce a certain protein, it activates the protein's gene–the portion of DNA that codes for that protein–and produces multiple copies of that piece of DNA in the form of messenger RNA, or mRNA. ... We now know that RNA can also act as enzymes (called ribozymes) to speed chemical reactions.
Explanation:
When the cell needs to produce a certain protein, it activates the protein's gene–the portion of DNA that codes for that protein–and produces multiple copies of that piece of DNA in the form of messenger RNA, or mRNA. ... We now know that RNA can also act as enzymes (called ribozymes) to speed chemical reactions.
For temperature, the reaction will slow down and eventually stop. Above 40 degrees the enzyme will denature. For the pH, amino acids' component atoms and molecules will begin to ionise. Due to this the enzyme will then change shape.
