Explanation:
in b/w A and T there will be two Hydrkgen bknds where as in b/w G and C there will be three hydrogen bonds
Answer:
DNA is a double helix and has base-pairing between nucleotides through the use of hydrogen bonds
Explanation:
The nucleotides are made up of a nitrogen base [base-pairing adenine (A) with thymine (T) and guanine (G) with cytosine (C)], a phosphate, and a deoxyribose (sugar); all of which are held together by hydrogen bonds. The binding allows the DNA to have a sugar-phosphate backbone connected with hydrogen bonds because they are firm but also easy to break (for DNA transcription)
