BIO 1040 TEST QUESTIONS AND ANSWERS
LATEST UPDATE
How is cytokinesis different in plant vs. animal cells?
Plant cells form a new cell wall to separate original cell into 2 new cells
Animal cells pinches to form 2 new cells
Human cells have how many chromosomes in total
46
What is semiconservative replication
In semiconservative replication, the original two strands of the double helix serve as
templates for 2 new strands of DNA. Each will consist of one original template strand
and one newly synthesized strand that is complementary to the template.
What is complimentary base pairing
Adenine only pairs with thymine
Guanine only pairs with cytosine
what is gene expression
synthesis of a protein from the information encoded in a gene.
What does the "T" base in DNA become in RNA?
"U" (Uracil)
What is the term for the overall shape of DNA?
Double Helix
True or False: transcription comes before translation
True
What is the difference between Mitosis and Meiosis?
Mitosis =2 identical daughter cells/ Meiosis =2 unique daughter cells
What are the 5 steps of Mitosis in order?
Interphase, Prophase, Metaphase, Anaphase, Telophase
Why are cell checkpoints important?
They regulate the cells functions and repair them when needed.
Mutations in 2 types of genes cause most cancers. Which 2 are correct?
tumor suppressor genes
What is a Codon?
The mRNA's code that is read in sets of 3 nucleotides
During DNA replication, Which Enzyme unwinds the double helix
DNA helicase
What happens if a FUNCTIONAL cell checkpoints cant fix a problem?
Cell death
What are the 3 phases of interphase in order?
G1, S, G2
True or false: Cytokinesis takes place differently in plant and animal cells.
True
How is cytokinesis different in plant vs. animal cells?
To separate: Plant cells form a new cell wall/ Animal cells "pinch"
