'Did you know that DNA can be damaged…and repaired?
DNA (deoxyribonucleic acid) is the hereditary material found in humans, animals, and organisms. DNA is in every cell in our bodies. Each cell’s nucleus has DNA, which is rolled into structures that are our chromosomes (23 pairs).
“Most genes contain the information needed to make functional molecules called proteins. (A few genes produce other molecules that help the cell assemble proteins.) The journey from gene to protein is complex and tightly controlled within each cell. It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression.'
