Answer the following question given this paragraph: 9.2 | DNA Replication By the end of this section, you will be able to: Explain the process of DNA replication Explain the importance of telomerase to DNA replication Describe mechanisms of DNA repair When a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis. The elucidation of the structure of the double helix provided a hint as to how DNA is copied. Recall that adenine nucleotides pair with thymine nucleotides, and cytosine with guanine. This means that the two strands are complementary to each other. For example, a strand of DNA with a nucleotide sequence of AGTCATGA will have a complementary strand with the sequence TCAGTACT (Figure 9.8). Q: During which phase does dna replication occur in the cell cycle? A:

OPTIONS:
- resting
- gap
- mitosis
- synthesis
