DNA Structure and Replication What does ligase do during replication of DNA? Joins nicks in DNA strands Makes copies of mRNA from DNA Digests mRNA when it is no longer needed Synthesizes the lagging strand Joins nicks in DNA strands Makes copies of mRNA from DNA Digests mRNA when it is no longer needed Synthesizes the lagging strand 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%? Increases Decreases Can not be compared Remains same Increases Decreases Can not be compared Remains same ANSWER DOWNLOAD EXAMIANS APP
