A nucleotide is made up of what 3 components? - ANSWER
✔✔phosphate group, pentose sugar (deoxyribose in DNA and ribose in
RNA), and a nitrogenous base
What nitrogenous bases are purines - ANSWER ✔✔Adenine and
Guanine
What nitrogenous bases are pyrimidines? - ANSWER ✔✔cytosine,
thymine, uracil
,How can you differentiate between purines and pyrimidines? -
ANSWER ✔✔purines are double-ringed while pyrimidines are single-
ringed
What are the differences between DNA and RNA? - 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 - ANSWER ✔✔nucleoside: pentose sugar
+ nitrogenous base
nucleotide: pentose sugar + nitrogenous base + phosphate group
What type of bonds bind nucleotide chains? - ANSWER
✔✔Phosphodiester bonds
What are the 4 requirements for a molecule to be genetic material? -
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? - ANSWER ✔✔cell's nucleus
what is a centrosome? - ANSWER ✔✔location in the cell that
contains centrioles
What are centrioles? - 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? - ANSWER
✔✔2 centrioles/1 centrosome
How many copies of each type of chromosome does each eukaryotic
cell typically have? - ANSWER ✔✔2 copies
what are homologous chromosomes? - ANSWER ✔✔copies of the
same type of DNA
What are non-homologous chromosomes? - ANSWER ✔✔copies of
different chromosomes with different DNA
What is mitosis? - ANSWER ✔✔cell division of one cell into 2 exact
duplicates

, What are the six stages of Mitosis in order? - ANSWER
✔✔interphase, prophase, prometaphase, metaphase, anaphase,
telophase and cytokinesis
What happens during mitosis interphase? - ANSWER ✔✔mitosis
stage that the cell is primarily in
chromosomes are uncondensed, so they are just hanging out in the
nucleus
1 centrosome < 2 centrioles
What happens during interphase s-phase? - ANSWER
✔✔Centrosome replication ( 2 centrosomes < 4 centrioles) occurs and
chromosome replication occurs (still uncondensed)
What happens during mitosis prophase? - ANSWER ✔✔centrioles
move to opposite ends of the cell using spindle fibers
nuclear membrane breaks down
chromatin (DNA) condenses into chromosomes (the "x"'s); bound by a
kinetochore that attracts mitotic spindle fibers
