CCBC BIO 110 FINAL PRACTICE
EXAMINATION 2026 QUESTIONS WITH
ANSWERS GRADED A+
◍ Which of the following events does not occur in prophase II.
Answer: formation of the chiasmata
◍ How many nucleotides are contained in a single codon?.
Answer: 3
◍ Polar covalent bonds.
Answer: Result from the unequal sharing of electrons
◍ Which of the following best describes semiconservative replication?.
Answer: A DNA molecule consists of one parental strand and one new
strand
◍ If a cell is in G2.
Answer: it has twice the amount of DNA present in telophase.
◍ If mitosis produced gametes in sexually reproducing organisms, then:.
Answer: chromosome number would double in each generation
◍ Atomic Mass.
Answer: # that indicates approx how much matter that atom contains
compared w/another atom (#protons + #neutrons)
◍ Vacuoles.
Answer: - store materials, waste, water- maintain hydrostatic pressure
◍ To prevent disastrous consequences, the eukaryotic cell cycle is controlled
by:.
Answer: a series of cell cycle checkpoints.
, ◍ Rough ER.
Answer: Manufactures proteins
◍ Lysosomes.
Answer: - contain enzymes that break down ingested materials- break down
damaged or unneeded organelles and proteins
◍ Fluid Mosaic Model.
Answer: Fluid- lipids and proteins can move in the membraneMosaic-
phospholipids; proteins (integral & peripheral); carbohydrates
◍ Element.
Answer: Substances that can not be broken down into simpler substances by
ordinary chemical reactions
◍ How is the 4-letter language of nucleic acids converted into the 20-word
language of amino acids?.
Answer: The 4 nucleic acid bases combine in 3-letter sequences that define
different amino acids.
◍ Why is only one strand of DNA transcribed into mRNA?.
Answer: Because the other strand would produce the same amino acid
sequence in reverse order
◍ Which of the following regions of a structural gene contains the information
that specifies an amino acid sequence?.
Answer: transcribed region
◍ Semi-conservative replication.
Answer: Each strand of parent DNA serves as a template for a new strand
◍ Active transport.
Answer: Requires cellular energy in the form of ATP. The molecules are
moving against the gradient (from high to low concentrations)
◍ Which purine base forms 3 hydrogen bonds when binding its
complementary nucleotide..
Answer: guanine
