BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The nucleic acid bases of two nucleotides are complementary to each other that are A-T, G-C. So, the complementary base of DNA sequence ‘TAGCATGAT’ will be ‘ATCGTACTA’.

Detailed explanation-2: -Complementary sequence: Nucleic acid sequence of bases that can form a double-stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.

Detailed explanation-3: -A always pairs with T (or in RNA, it pairs with U) G always pairs with C. So if you know the sequence of bases on one side of the ‘ladder, ’ you can automatically determine the sequence of bases on the other side. The strands are therefore complementary to each other. Each side of the ladder is called a strand.

Detailed explanation-4: -Figure 9.8 The two strands of DNA are complementary, meaning the sequence of bases in one strand can be used to create the correct sequence of bases in the other strand. Because of the complementarity of the two strands, having one strand means that it is possible to recreate the other strand.

Detailed explanation-5: -The base pairs on one strand of the DNA bind with the base pairs of the other strand specifically. A always pairs with T with two hydrogen bonds and G always pairs with C with three hydrogen bonds. So if one strand is ATGCTTGA then the complementary strand will be TACGAACT.
