Study Notes
Structure Visualization
- A cell is the basic unit of life
- Chromosomes contain DNA, which carries genes
- Genes are segments of DNA that code for proteins
- hnRNA (Heterogeneous Nuclear RNA) is the precursor molecule to mRNA
- mRNA (Messenger RNA) carries genetic information from DNA to be used for protein synthesis
- Proteins are the final product of gene expression and perform various functions in the body
Purpose of a Gene
- Genes serve as blueprints for proteins, determining their structure
- Genes control where, when, and how much protein is produced
Effects of Genes on the Body
- Genes play a role in cell functions like tissue repair and production of enzymes (e.g., starch digestion).
- Genes influence the overall development and functionality of cells and bodies
