Question

Which bases are found in a strand of dna

Answer 1

Answer:

The nucleic acid sequences are complementary and parallel, but they go in opposite directions, hence the antiparallel designation. The antiparallel structure of DNA is important in DNA replication because it replicates the leading strand one way and the lagging strand the other way.

Answer 2

Answer:

• A polynucleotide is DNA. Deoxyribose sugar, a phosphate group, and a nitrogenous base make up each nucleotide.
• On the two opposing strands of the DNA double helix are molecules called nucleotides that interact chemically.
• The two strands of DNA are held together by these chemical bonds, which function like rungs on a ladder. DNA contains the bases adenine (A), cytosine (C), guanine (G), and thymine (T) (T). These bases come in particular pairs (A with T, and G with C).
• Thymine and cytosine are pyrimidine bases, while adenine and guanine are purine bases. Base pairing takes place in a double stranded DNA between the complementary bases of the two strands. By means of two and three hydrogen bonds, A and T pair, and G and C pair.
