3: It's in the Genes

Page 1

Protein Synthesis Proteins are produced through the process of transcription and translation. During transcription one DNA strand is copied and makes a strand of RNA. In translation ribosomes make proteins using mRNA. The sequence of nucleotides determines the sequence of amino acids in the protein. Changes in genetic material may change the structure and function of protein, and therefore, the traits of an organism.

Chromosomes and DNA

Genes are passed from from parent to child and therefore, traits are inherited. Some diseases may be inherited, caused by DNA mutation.

Meiosis

Meiosis is the process of cell division where the resulting daughter cells result with half of the chromosome count as a typical human cell. The resulting sex cells may join with another to combine each half count of chromosomes, creating the necessary 46 chromosomes for a human.
