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
