CORRECT ANSWERS|EXCELLENT
SCORES
A nucleotide is made up of what 3 components? - correct-answer-phosphate
group, pentose sugar (deoxyribose in DNA and ribose in RNA), and a nitrogenous
base
What nitrogenous bases are purines - correct-answer-Adenine and Guanine
What nitrogenous bases are pyrimidines? - correct-answer-cytosine, thymine,
uracil
, Page |2
How can you differentiate between purines and pyrimidines? - correct-answer-
purines are double-ringed while pyrimidines are single-ringed
What are the differences between DNA and RNA? - correct-answer-DNA: double
stranded, has deoxyribose sugar(hydroxyl group at 2' carbon), bases: A, T, G, C
RNA: single stranded, has ribose sugar(one oxygen is removed from the 2'
Carbon), bases: A, U, G, C
Nucleoside vs Nucleotide - correct-answer-nucleoside: pentose sugar +
nitrogenous base
nucleotide: pentose sugar + nitrogenous base + phosphate group
What type of bonds bind nucleotide chains? - correct-answer-Phosphodiester
bonds
What are the 4 requirements for a molecule to be genetic material? - correct-
answer-1.) Must contain important info to encode hereditary traits
2.) Must be capable of replication
3.) Must be capable of variation by mutation
4.) Must be able to express information

Where are chromosomes located? - correct-answer-cell's nucleus
what is a centrosome? - correct-answer-location in the cell that contains
centrioles
What are centrioles? - correct-answer-microtubules that produce mitotic spindle
fibers, aids in cell division, and make up the cytoskeleton of the cell
How many centrioles are there for every centrosome? - correct-answer-2
centrioles/1 centrosome
How many copies of each type of chromosome does each eukaryotic cell typically
have? - correct-answer-2 copies
what are homologous chromosomes? - correct-answer-copies of the same type of
DNA
, Page |4
What are non-homologous chromosomes? - correct-answer-copies of different
chromosomes with different DNA
What is mitosis? - correct-answer-cell division of one cell into 2 exact duplicates
What are the 3 codons that represent STOP? - correct-answer-UAA, UAG, UGA
What is the chemical composition of an amino acid? - correct-answer-Amino
group, carboxyl group, central carbon, and a variable R-group
How are amino acids linked in chains to form a protein? - correct-answer-Peptide
bond caused by peptidyl transferase
Describe the structure and function of rRNA - correct-answer-Ribosomal RNA-
forms the two subunits in a ribosome along with proteins.
The ribosome moves along the mRNA strand during proteins synthesis.
