When DNA makes a copy or replicates itself, identify the correct nitrogen base pairing
A pairs with G & C pairs with T
A pairs with U & C pairs with T
A pairs with T & G pairs with U
A pair with T & G pairs with C
The image shows the different parts of a NUCLEOTIDE; identify the statement that is correct
A= phosphate B= 5 carbon sugar C= nitrogenous base
A= 5 carbon sugar B= 5 phosphate C= nitrogenous base
A= nitrogenous base B= 5 carbon sugar C= phosphate
None are correct

TACG
ATCG
CGAT
GATC
Identify the correct order for DNA replication
DNA unwinds, Nitrogen bases added, 2 identical DNA molecules created
Nitrogen bases added, DNA unwinds, 2 identical DNA molecules created
2 identical DNA molecules created, Nitrogen bases added, DNA unwinds
None are correct
During TRANSCRIPTION (to write) of Protein Synthesis, if the DNA strand reads TACACT what would be correct mRNA strand
UGAAUG
AUGUGA
ATGTGA
TGAATG
During TRANSLATION (to read), if the mRNA reads AUGUGA what would the correct AMINO ACIDS be
Stop, Met(start)
Ile, Stop
Met(start), Trp
Met(start), Stop
When mutations occur sometimes NO change occurs in the formation of the protein. Identify which of the different MUTATIONS would this occur
Silent
Missense
Nonsense
Insertion or Deletion
When POINT MUTATIONS and/or FRAME SHIFT MUTATIONS occurs and the base in the DNA changes it leads to change(s) in the formation of the protein. Identify which of the different MUTATIONS would this occur
Silent only
Missense & Nonsense ONLY
Missense, Nonsense & Insertion/Deletion
None are correct
When POINT MUTATIONS and/or FRAME SHIFT MUTATIONS occurs and the base in the DNA changes it leads to change(s) in the formation of the protein. Identify the correct statement that pertains to these two types of DNA mutations
Both could lead to phenotype changes
Both have changes in the mRNA & Protein sequences
Both could occur due to environmental factors & carcinogens
ALL are correct
The original DNA strand reads TAC/CGA/TCA/ATT.
The mutated DNA strand reads TAC/CGA/TCA/ATA.
Determine if there a disorder has occurred and the type of mutation.
Yes, type of mutation SILENT
Yes, type of mutation MISSENSE
Yes, type of mutation NONSENSE
No, there was no change to the DNA
APOPTOSIS is

Controlled cell growth that affects the cells in a harmful way
Uncontrolled cell growth that does not affect the cells in a harmful way
Uncontrolled cell growth that affects the cells in a harmful way
CANCER is
Controlled cell growth that does not affect the cells in a harmful way
Controlled cell growth that affects the cells in a harmful way
Uncontrolled cell growth that does not affect the cells in a harmful way
Uncontrolled cell growth that affects the cells in a harmful way
Identify the part of THE CELL CYCLE that the cell "gets ready to divide"
G1
S
G2

Identify the part of THE CELL CYCLE that the cell "grows and makes essential cell parts for cellular functioning"
G1
S
G2
Interphase
Identify the part of THE CELL CYCLE that the cells "genetic material is synthesized and doubled from 2n to 4n"
G1
S
G2
Interphase
Identify the part of THE CELL CYCLE that the cell "spends majority it's time in throughout it's life span "
G1
S

Mitosis is the cellular reproduction for
Growth of overall organism
Repair of damaged cells
Replacement of old cells
All are correct
Which part of MITOSIS do the chromosomes "meet in the middle"
PROphase
METAphase
ANAphase
TELOphase
Identify the INCORRECT statement in regards to cells created during MITOSIS
DNA of cells are identical
Mitosis creates 2 new cells each division
Each new cell is 2n or considered to be diploid
Cells created are for gametes or sperm and eggs
During CYTOKINESIS, a plant cell would divide its cytoplasm a little different than an animal cell. Identify the correct statement regarding the differences between plant & animal cells during this part of cell division
Plant cells divide into four new cells while animals divide into two.
Plant cells have different DNA in new cells while animal cells have identical DNA.
Plant cells divide with a cell plate in between while animal cells separate into two new cells. Both DNA is identical.
None are correct
