Explanation:
Genes and Chromosomes. Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Chromosomes : Chromosomes are the structures made up of chromatin. Chromatin is the threads of DNA that get condensed to form chromosomes.
Genes : Genes are the segments of DNA that code for proteins. Hence, each chromosome is made up of DNA and contains many genes because of segments of DNA.
DNA : The complementary DNA or cDNA is synthesized, or manufactured from an mRNA or messenger RNA template. It is synthesized in a reaction that is catalyzed by the reverse transcriptase and DNA polymerase enzymes.
