DNA Structure and Replication What does ligase do during replication of DNA? Digests mRNA when it is no longer needed Joins nicks in DNA strands Makes copies of mRNA from DNA Synthesizes the lagging strand Digests mRNA when it is no longer needed Joins nicks in DNA strands Makes copies of mRNA from DNA Synthesizes the lagging strand ANSWER DOWNLOAD EXAMIANS APP
DNA Structure and Replication Taylor, Woods and Hughes labeled Vicia DNA by allowing new DNA synthesis in the presence of radioactive thymine. After DNA replication (S phase of the cell cycle), it was observed that both (a) and (b) both chromatids of a chromosome were labeled only one chromatid of a chromosome was labeled neither chromatid was labeled both (a) and (b) both chromatids of a chromosome were labeled only one chromatid of a chromosome was labeled neither chromatid was labeled ANSWER DOWNLOAD EXAMIANS APP
