The right answers are mentioned in the picture.
- A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.
- It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.
