(VERIFIED ANSWERS) |ALREADY GRADED A+(2025)
A nucleotide is made up of what 3 components? - (answers)phosphate group, pentose sugar
(deoxyribose in DNA and ribose in RNA), and a nitrogenous base
What nitrogenous bases are purines - (answers)Adenine and Guanine
What nitrogenous bases are pyrimidines? - (answers)cytosine, thymine, uracil
How can you differentiate between purines and pyrimidines? - (answers)purines are double-ringed while
pyrimidines are single-ringed
What are the differences between DNA and RNA? - (answers)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 - (answers)nucleoside: pentose sugar + nitrogenous base
nucleotide: pentose sugar + nitrogenous base + phosphate group
What type of bonds bind nucleotide chains? - (answers)Phosphodiester bonds
What are the 4 requirements for a molecule to be genetic material? - (answers)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? - (answers)cell's nucleus

what is a centrosome? - (answers)location in the cell that contains centrioles
What are centrioles? - (answers)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? - (answers)2 centrioles/1 centrosome
How many copies of each type of chromosome does each eukaryotic cell typically have? - (answers)2
copies
what are homologous chromosomes? - (answers)copies of the same type of DNA
What are non-homologous chromosomes? - (answers)copies of different chromosomes with different
DNA
What is mitosis? - (answers)cell division of one cell into 2 exact duplicates
What are the six stages of Mitosis in order? - (answers)interphase, prophase, prometaphase, metaphase,
anaphase, telophase and cytokinesis
What happens during mitosis interphase? - (answers)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? - (answers)Centrosome replication ( 2 centrosomes < 4
centrioles) occurs and chromosome replication occurs (still uncondensed)
What happens during mitosis prophase? - (answers)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
What happens during mitosis prometaphase? - (answers)centrioles have reached polar regions and
mitotic spindle fibers have connected to the kinetochore
What happens during mitosis metaphase - (answers)all chromosomes are lined up on the metaphase
plate
What happens during mitosis Anaphase? - (answers)mitotic spindle fibers pull chromosomes apart into
chromatids (4n)
What happens during mitosis telophase? - (answers)nuclear envelope reforms
plasmo-membrane is pinched; sister chromatids are still condensed at this point
What happens during cytokinesis? - (answers)cells split off; genetic material becomes uncondensed
