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? All of these The many different amino acid R groups on proteins confer many different shapes. DNA has one main function in cells whereas proteins have many. Some S amino acids cause proteins to bend; others cause protein to flatten. All of these The many different amino acid R groups on proteins confer many different shapes.

DNA Structure and Replication Which of the following is used to determine the appropriate stringency (Wallace rule)? Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) Tm = 69.3° + 0.41 (%)G+C -650/1 Tm = 4 x (No.of A:T base pair) + 2 x (No.of G:C base pair) Tm = 2 x (No.of G:C base pair) + 4 x (No.of A:T base pair) Tm = 4 x (No.of G:C base pair) + 2 x (No.of A:T base pair) ANSWER DOWNLOAD EXAMIANS APP
