The correct answer will be:
1. A segment that contains the information for making protein-gene
2. A complex molecule containing the genetic code-DNA
3. A nucleic acid that participates in the synthesis of proteins gene-RNA
Explanation:
DNA is a large molecule which acts as a genetic material in the most of the organisms. It is made up of nucleotides which is composed of sugar-phosphate backbone and nitrogenous bases (adenine guanine, cytosine and thymine). It is the order of these nitrogenous bases that acts as genetic code.
The structure of DNA is divided into small physical and functional segments of heredity called gene which provides the instructions for the synthesis of proteins. The order of the nitrogenous bases in genes code for proteins through a process called transcription in which each strand of DNA acts as template strand making a messenger molecule called mRNA. This mRNA undergoes the process of translation which synthesizes proteins.
Thus, segment that contains the information for making protein-gene, complex molecule containing the genetic code-DNA, nucleic acid that participates in the synthesis of proteins gene-RNA is the correct answer.
