Answer:
true
Explanation:
DNA synthesis is performed by the enzyme DNA polymerase. However, DNA polymerase requires the presence of a free 3' OH on the existing DNA or RNA segment. The enzyme primase forms small RNA segments that serve as primers. Primers are formed by using the DNA template strands and have free 3' OH ends. DNA polymerase extends the primers by adding deoxyribonucleotides according to the sequence of the DNA template strand. Therefore, DNA polymerases are the enzymes of primer elongation.
nitrogen, carbon, hydrogen, oxygen, phosphorous, and sulfur
<h2>Answer with Explanation </h2>
Cellular respiration is a process in which chemical reactions occurs that allows the body to take glucose and transform it into ATP. ATP is a more readily available form of energy for the body than glucose. Cells need energy to perform tasks, and respire to break the chemical bonds in ATP and then use it for energy. So, respiration occurs at all times in the human body, and is essential for survival.
