Detailed explanation-1: -During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.
Detailed explanation-2: -The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health.
Detailed explanation-3: -The DNA polymerase enzyme reads the DNA sequence during proofreading.
Detailed explanation-4: -Only about 1 percent of DNA is made up of protein-coding genes; the other 99 percent is noncoding. Noncoding DNA does not provide instructions for making proteins.
Detailed explanation-5: -Some genes encode proteins that are not enzymes. Enzymes are just one category of protein. There are many non-enzyme proteins in cells, and these proteins are also encoded by genes.
