Alphonso Olson · Answer

A ) adenine and thymineExplanation: DNA has two types of nitrogenous bases: purines and pyrimidines. Adenine and guanine are purines while cytosine and thymine are pyrimidines.  A purine always pairs with a pyrimidine. Hence, adenine in DNA pairs with thymine while guanine pairs with cytosine. This is done to maintain the constant width of the double helix throughout the length.

bExplanation:

Alphonso Olson · Answer

Each nucleotide base can hydrogen-bond with a specific partner base in a process known as complementary base pairing: Cytosine forms three hydrogen bonds with guanine, and adenine forms two hydrogen bonds with thymine. These hydrogen-bonded nitrogenous bases are often referred to as base pairs.

Explanation:strands of phosphate sugar backbone with complementary nitrogenous base pairs bound into a double helix

Alphonso Olson · Answer

Adenine and thymine pair up. Just remember ATCG in that order, showing that adenine and thymine pair up, and so do cytosine and guanine

Alphonso Olson · Answer

Answer - AAdenine pairs up with thymine, and cytosine pairs up with guanine.

Alphonso Olson · Answer

It would be the first option. Adenine and thymine.

Alphonso Olson · Answer

The first one is correct. A always pairs with T, and C always pairs with G

Alphonso Olson · Answer

They form hydrogen bonds between opposing dna which forms the twister ladder of dna
