Options: characteristics of genetic code of humans
- contains over 3 billion base pairs
- can help explain genetic diseases
- can only help understand human genetics
Explanation:
The human genetic code is the “set of rules” which defines the coding process of the genetic material by a living cell.
The total genetic code or the genome of an organism consists of 3 billion nitrogenous base pairs with 21,000 genes that code and encode to form different types of proteins through translation and transcription. They contain 23 pairs of chromosomes.
The genetic code and genome help a lot in understanding;
- hereditary diseases which are inherited through generations like sickle cell anemia
- evaluate or predict risk factors of diseases like heart diseases, diabetes, etc and make necessary lifestyle modifications and other take preventive measures to prevent such diseases
- to understand about human genetics, evolution, ancestry, history, evolutionary changes, migratory patterns and other anthropological factors
