,A nucleotide is made up of what 3 components? - correct ans:phosphate
group, pentose sugar (deoxyribose in DNA and ribose in RNA), and a
nitrogenous base
What nitrogenous bases are purines - correct ans:Adenine and Guanine
What nitrogenous bases are pyrimidines? - correct ans:cytosine, thymine,
uracil
How can you differentiate between purines and pyrimidines? - correct
ans:purines are double-ringed while pyrimidines are single-ringed
What are the differences between DNA and RNA? - correct ans: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 ans:nucleoside: pentose sugar +
nitrogenous base
nucleotide: pentose sugar + nitrogenous base + phosphate group
What type of bonds bind nucleotide chains? - correct ans:Phosphodiester
bonds
What are the 4 requirements for a molecule to be genetic material? - correct
ans: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 ans:cell's nucleus
what is a centrosome? - correct ans:location in the cell that contains
centrioles
What are centrioles? - correct ans: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 ans:2
centrioles/1 centrosome
How many copies of each type of chromosome does each eukaryotic cell
typically have? - correct ans:2 copies
what are homologous chromosomes? - correct ans:copies of the same type of
DNA
What are non-homologous chromosomes? - correct ans:copies of different
chromosomes with different DNA
What is mitosis? - correct ans:cell division of one cell into 2 exact duplicates
What are the six stages of Mitosis in order? - correct ans:interphase,
prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis
What happens during mitosis interphase? - correct ans:mitosis stage that the
cell is primarily in
chromosomes are uncondensed, so they are just hanging out in the nucleus
