SFSU BIO 230 PRACTICE EXAM SCRIPT 2026
TESTED QUESTIONS WITH FULL SOLUTIONS
GRADED A+
◉ Prion. Answer: Are misfolded proteins that cause other similar
proteins to misfold
Not made of cells. Not have DNA RNA. Are not viruses
Are causative of Mad cow disease
◉ Non-Coding DNA. Answer: Promoters and introns(parts of process)
98% of genome is noncoding
- DNA that doesn't get coded into a protein
◉ RNA. Answer: Ribonucleic acid; a type of nuclei can acid that carries
codes for making proteins from the nucleus to the ribosomes
◉ Gene. Answer: DNA sequence needed to encode a functional protein
or RNA
◉ Genome. Answer: The full set of DNA present in an individual
organism
,All the chromosome and protein in the nucleus
◉ Chromosome. Answer: Threadlike structure of nucleic acids and
protein found in the nucleus of most living cells, carrying genetic info in
the form of genes
Package that holds some DNA and proteins, part of the genome (humans
have 46)
◉ Cytosine. Answer: A nitrogen containing pyrimidine base found in
nucleic acids,(pairs of guanine)
◉ Dictionary of the Genetic Code. Answer:
◉ Carbohydrates. Answer: Complex structure; many sugar subunits
main source of energy
◉ Nucleic Acids. Answer: Make DNA and RNA stores genetic info
found in nucleus
◉ Proteins. Answer: Made of amino acids that are folded up, do all the
work in the cells
◉ Mutations. Answer: Change in structure of gene
-
, -
-
◉ Covalent Bond. Answer: Electrons sharing bonds
◉ Ionic Bond. Answer: Electrical attraction between oppositely charged
ions
◉ Hydrogen Bond. Answer: (Weak) electrons are attracted to each other
◉ Nucleotide. Answer: Make up DNA, information storage and transfer
nucleic acid
◉ Structure. Answer:
◉ Functions. Answer:
◉ Structure of living things. Answer: - cells, tissues, atoms, electrons,
organelles, molecules
◉ Codons. Answer: 3 nucleotides together to form genetic codes
◉ Use evidence. Answer:
