NEET BIOLOGY

Detailed explanation-1: -The four bases in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).

Detailed explanation-2: -These chemical bonds act like rungs in a ladder and help hold the two strands of DNA together. There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T).

Detailed explanation-3: -ACGT is an acronym for the four types of bases found in a DNA molecule: adenine (A), cytosine (C), guanine (G), and thymine (T). A DNA molecule consists of two strands wound around each other, with each strand held together by bonds between the bases. Adenine pairs with thymine, and cytosine pairs with guanine.

Detailed explanation-4: -The nitrogenous base found in the DNA are ATCG. The thiamine is replaced with uracil in the RNA molecule. So, the nitrogenous bases in RNA are AUCG. Adenine and guanine are the purine bases and the uracil and cytosine are the pyrimidine bases in the RNA. The purines are the double ring nitrogenous bases.

Detailed explanation-5: -Nucleotide The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine. DNA and RNA molecules are polymers made up of long chains of nucleotides.
