A nucleotide is made up of what 3 phosphate group, pentose sugar (deoxyribose in
components? DNA and ribose in RNA), and a nitrogenous base
What nitrogenous bases are purines Adenine and Guanine
What nitrogenous bases are cytosine, thymine, uracil
pyrimidines?
How can you differentiate between purines are double-ringed while pyrimidines are
purines and pyrimidines? single-ringed
What are the differences between DNA: double stranded, has deoxyribose
DNA and RNA? 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 nucleoside: pentose sugar + nitrogenous base
nucleotide: pentose sugar + nitrogenous base +
phosphate group
,What type of bonds bind nucleotide Phosphodiester bonds
chains?
What are the 4 requirements for a 1.) Must contain important info to encode
molecule to be genetic material? 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? cell's nucleus
what is a centrosome? location in the cell that contains centrioles
What are centrioles? microtubules that produce mitotic spindle fibers,
aids in cell division, and make up the cytoskeleton
of the cell
How many centrioles are there for 2 centrioles/1 centrosome
every centrosome?
How many copies of each type of 2 copies
chromosome does each eukaryotic
cell typically have?
what are homologous copies of the same type of DNA
chromosomes?
What are non-homologous copies of different chromosomes with different
chromosomes? DNA
What is mitosis? cell division of one cell into 2 exact duplicates
, What are the six stages of Mitosis in interphase, prophase, prometaphase, metaphase,
order? anaphase, telophase and cytokinesis
What happens during mitosis mitosis stage that the cell is primarily in
interphase? chromosomes are uncondensed, so they are just
hanging out in the nucleus
1 centrosome < 2 centrioles
What happens during interphase s- Centrosome replication ( 2 centrosomes < 4
phase? centrioles) occurs and chromosome replication
occurs (still uncondensed)
What happens during mitosis centrioles move to opposite ends of the cell using
prophase? spindle fibers
nuclear membrane breaks down
chromatin (DNA) condenses into chromosomes
(the "x"'s); bound by a kinetochore that attracts
mitotic spindle fibers
What happens during mitosis centrioles have reached polar regions and mitotic
prometaphase? spindle fibers have connected to the kinetochore
What happens during mitosis all chromosomes are lined up on the metaphase
metaphase plate
What happens during mitosis mitotic spindle fibers pull chromosomes apart into
Anaphase? chromatids (4n)
What happens during mitosis nuclear envelope reforms
telophase?
plasmo-membrane is pinched; sister chromatids are
still condensed at this point
