What are genes? - CORRECT ANSWER Genes are sections of DNA that control a single genetic trait and code for a protein.
What is the central dogma of molecular biology? - CORRECT ANSWER DNA -> RNA -> Protein
What process makes mRNA? - CORRECT ANSWER transcription
What process makes proteins? - CORRECT ANSWER translation
Name the base pairs in DNA - CORRECT ANSWER A-T
G-C
Name the base pairs in RNA - CORRECT ANSWER A + U, C + G
What determines the shape of a protein? - CORRECT ANSWER sequence of amino acids
What is genetic recombination? - CORRECT ANSWER the production of offspring with combinations of traits differing from either parent
What are two types of genetic recombination? - CORRECT ANSWER crossing over and independent assortment
Crossing over is - CORRECT ANSWER Process in which homologous chromosomes exchange portions of their chromatids during meiosis. Independent assortment - CORRECT ANSWER Independent segregation of genes during the formation of
gametes
How can a mutation affect a protein? - CORRECT ANSWER It can change the protein, not make a protein,
have a protein that doesn't stop, or not cause a change.
Which mutations are cause larger changes to a protein? - CORRECT ANSWER Frameshift mutations, insertion/deletion.

Is DNA identical in all cells? - CORRECT ANSWER Yes!
Complete dominance - CORRECT ANSWER a relationship in which one allele is completely dominant over

Incomplete dominance - CORRECT ANSWER Situation in which one allele is not completely dominant over another allele, causing a mix of traits.
Codominance - CORRECT ANSWER A condition in which neither of two alleles of a gene is dominant or recessive, and both traits are expressed.
Sex-linked traits - CORRECT ANSWER Traits controlled by genes located on sex chromosomes.
Chi-square - CORRECT ANSWER Involves categorical variables. Looks at 2 distributions of categorical data
to see if they differ from each other.
Where does translation occur? - CORRECT ANSWER ribosome
Where does transcription occur? - CORRECT ANSWER nucleus
