DNA test review:

Gene

• The portion of DNA that determines traits
• Basic unit of life
• Many genes structured together

Many genes structured together

• Chromosome
• DNA
• Trait

Mutations

• A feature of an organsim
• Structural changes to genes
• pair of parallel helices about common axis, especially that in the DNA molecule.

Double Helix

• a pair of parallel helices intertwined about a common axis, especially that in the structure of the DNA molecule.
• sickle cell anemia caused by a single point mutation.
• The basic physical and functional unit of heredity made up DNA.

Basic unit of life

• Cell
• Chromosome
• Trait

Trait

• A feature of an organism
• A single highly organized and structured piece of DNA
• Different forms or versions

Variants

• Different forms or versions of something
• Biomolecules made up of amino acids and founds in all living cells perform bodily functions
• The basic structural and functional unit of living organism.

Alleles

• The different forms a gene may have for a trait
• Passing traits from parent to offspring
• having 2 alleles that are the same for a trait

Passing traits from parent to offspring

• Heredity
