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 Synthesizes the lagging strand Makes copies of mRNA from DNA Digests mRNA when it is no longer needed Joins nicks in DNA strands Synthesizes the lagging strand Makes copies of mRNA from DNA ANSWER DOWNLOAD EXAMIANS APP

DNA Structure and Replication In the study of one experiment it was found that the value of Tm for DNA is = 40° C. If the cell has 20% GC at the above Tm, then what will be value of 'Tm' if the GC% increases to 60%? Remains same Increases Can not be compared Decreases Remains same Increases Can not be compared Decreases ANSWER DOWNLOAD EXAMIANS APP
