Under normal circumstances, it is not possible for adenine to pair up with guanine or cytosine, nor for any other mismatches to occur. describe the two factors that prevent a mismatch from occurring

The chemical structure of adenine only allows it to form a hydrogen bond with thymine. While the structure of guanine allows it to form a hydrogen bond with cytosine. DNA Polymerase will then proofread a strand of DNA to ensure there is no mismatching bases.

To solve this integral, what you can do is split it up as follows: (1) ∫40(x2−4)dx=∫40(x2)dx−∫40(4)dx. to integrate  4  as an  indefinite integral, a good rule of thumb is  by  an equation below  for  polynomials; . (2) ∫xa=xa+1a+1+c , where a is any number. c denotes some constant that is crucial when doing
