A gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA). Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis. gene (def) is a segment of DNA that codes for a functional product (mRNA, tRNA, or rRNA).

DNA (DNA = deoxyribonucleic acid) â¢ DNA is the genetic material of all living cells and of many viruses. â¢ DNA is: an alpha double helix of two polynucleotide strands. â¢ The genetic code is the sequence of bases on one of the strands.â¢ A gene is a specific sequence of bases which has the information for a particular protein. â¢ DNA is self-replicating-it can make an identical copy of itself.rotein Synthesis Gene-A section of DNA containing a particular sequence of bases that codes for a specific protein. Protein Synthesis-The transcription of a specific DNA base sequence into mRNA and its translation, by a ribosome, into a particular amino acid sequence forming a protein.
