Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
<span>As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.</span>
Answer: answer
Explanation: Using PCR, a DNA sequence can be amplified millions or billions of times, producing enough DNA copies to be analyzed using other techniques. For instance, the DNA may be visualized by gel electrophoresis, sent for sequencing, or digested with restriction enzymes and cloned into a plasmid.
Answer:
__Rigor mortis__________ is caused by the lack of adenosine triphosphate (ATP) to the muscles
Explanation:
The rigor mortis corresponds to the stiffness of the muscles (they cannot contract or elongate) due to the lack of ATP, where I fixed the bridges between actin and myosin. This event happens when the oxygen transporting organs stop working.
