Example intro biology quiz questions with answers

Which organelle produces most of the cell's ATP?The mitochondrion. It runs cellular respiration, which releases energy from glucose in a form the cell can use.

True or false: DNA replication is semiconservative.True. Each new double helix keeps one original strand and one newly synthesized strand.

What does RNA polymerase do during transcription?It builds an RNA strand by reading a DNA template strand, because it makes RNA only in the 5' to 3' direction.

Which phase of mitosis separates sister chromatids?Anaphase. Spindle fibers pull the sister chromatids toward opposite poles of the cell.

In a dihybrid cross of two heterozygous parents, what fraction of offspring show both dominant traits?9/16. Independent assortment gives a 9:3:3:1 phenotype ratio, and the 9 group shows both dominant traits.
