Q36. Is there always be an equal number of adenine and thymine nucleotides in molecule? Why?Q37. Is there always going to be an equal number of guanine and cytosine nucleotides in a molecule? Why?Q38. The side of the ladder are made up of alternating ______ and _______ molecules. The steps (or rungs) of the ladder are made up of ______ held together by hydrogen bonds.

Sagot :


Since adenine is paired with thymine their number will be always equal.

Guanine and cytosine will be also equal in number because they are also a pair.

the side of the ladder are made of alternating sugar and phosphate molecules. while the steps are made base pairs.
