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
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
, 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 six stages of Mitosis in order? - CORRECT ANSWER -
interphase, prophase, prometaphase, metaphase, anaphase, telophase and
cytokinesis
What happens during mitosis interphase? - CORRECT 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? - CORRECT ANSWER -
Centrosome replication ( 2 centrosomes < 4 centrioles) occurs and chromosome
replication occurs (still uncondensed)
What happens during mitosis prophase? - CORRECT 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
