1. What is the structure of a DNA molecule? 2. What are the main functions of DNA in a cell? 3. What is common in the structure of DNA and RNA molecules?

1) DNA has the structure of a right-handed chain, consisting of two antiparallel strands, which contain nucleotides containing nitrogenous bases (adenine, thymine, guanine and cytosine).

2) DNA (like RNA) performs the function of storing and transmitting information. In the course of the cell cycle, information is read from it and subsequently proteins are formed, from which all the structural components of the cell are built.

3) The DNA and RNA molecules contain nucleotides that include nitrogenous bases.
