Biology EOC -OHIO Review Test
Papers with Correct Solutions 2025-
2026 Latest Update.
What are genes? - 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? - Answer DNA -> RNA -> Protein
What process makes mRNA? - Answer transcription
What process makes proteins? - Answer translation
Name the base pairs in DNA - Answer A-T
G-C
Name the base pairs in RNA - Answer A + U, C + G
What determines the shape of a protein? - Answer sequence of amino acids
What is genetic recombination? - Answer the production of offspring with combinations of
traits differing from either parent
What are two types of genetic recombination? - Answer crossing over and independent
assortment
Crossing over is - Answer Process in which homologous chromosomes exchange portions of
their chromatids during meiosis.
Independent assortment - Answer Independent segregation of genes during the formation
of gametes
, Why is a DNA mutation harmful? - Answer A mRNA sequence will always have the mutation.
A mutation on mRNA isn't as bad, as mRNA can be repaired if damaged.
Is DNA identical in all cells? - Answer Yes!
Complete dominance - Answer a relationship in which one allele is completely dominant
over another
Incomplete dominance - Answer Situation in which one allele is not completely dominant
over another allele, causing a mix of traits.
Codominance - Answer A condition in which neither of two alleles of a gene is dominant or
recessive, and both traits are expressed.
Sex-linked traits - Answer Traits controlled by genes located on sex chromosomes.
Chi-square - Answer Involves categorical variables. Looks at 2 distributions of categorical
data to see if they differ from each other.
Where does translation occur? - Answer ribosome
Where does transcription occur? - Answer nucleus
genetic engineering - Answer Process of making changes in the DNA code of living organisms
What is the goal of genetic engineering? - Answer to produce organisms with new &
improved characteristics and correct a malfunction
What are restriction enzymes? - Answer They cut the DNA into specific parts
What is cloning used for? - Answer Cloning can be used to make a copy of a particularly good
strain of plant
