What provides the energy for DNA synthesis?
Ribonucleoside triphosphates (NTP’s) are also required to initiate and sustain DNA synthesis. NTP’s are used in the synthesis of RNA primers and ATP is used as an energy source for some of the enzymes needed to initiate and sustain DNA synthesis at the replication fork.
Can you identify the components of a DNA strand?
Can you identify the components of a DNA strand? DNA is comprised of four different types of nucleotides. Each one is made up of a pentose sugar, a phosphate group, and one of four nitrogenous bases. Adenine, guanine, cytosine and thymine are nitrogenous bases.
What are the three component of DNA?
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
