WebMar 8, 2024 · The four types of nitrogen bases present in a nucleotide are adenine (A), thymine (T), guanine (G), and cytosine (C). Thymine is also known as 5-methyl uracil which is unique and in DNA. The nucleotides are attached to each other to form two long strands of DNA that spiral with each other to create a structure called a double helix. WebDNA replication is the process of copying the parent DNA helix into two identical daughter helices. The process is semi-conservative, which means that one parent strand is passed down to each daughter strand. The process begins when helicase unwinds the double helix and separates the two strands to create the replication fork.

WebMay 29, 2024 · DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen. The two strands of DNA have to be temporarily separated from each other; this job is done by a special enzyme, helicase, that helps unwind and separate the DNA helices (Figure 4). WebDNA helicase unwinds the double helix, so (A) is true and therefore incorrect. Choice (B), DNA ligase seals the discontinuous Okazaki fragments, is also true. Eliminate it. In the presence of DNA polymerase, DNA strands always grow in the 5' to 3' direction as complementary bases attach. Therefore, (D) is also incorrect.
