Questions And Answers |
Guaranteed Success
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
