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

DNA Structure and Replication The higher order structure of DNA shows symmetry, whereas the higher order structures of most proteins do not. Why isn't protein shape more regular like DNA? The many different amino acid R groups on proteins confer many different shapes. Some S amino acids cause proteins to bend; others cause protein to flatten. All of these DNA has one main function in cells whereas proteins have many. The many different amino acid R groups on proteins confer many different shapes.
