The shape of the DNA Molecule is
a double helix
twisted
two strands held together by hydrogen bond
all of the above
During interphase DNA is replicated. Which stage of interphase does DNA replication occur?
G1
S
G2
Mitosis
As the cell prepares to go through mitosis it must pass through checkpoint G2. What is being checked? (Diagram)
cell size, nutrients, DNA damage
cell size, DNA has replicated
chromosome attachment to spindle fibers
What process occurs at S stage of interphase?
DNA replication
DNA transcription
DNA translation
DNA replication's product is
two double strands of DNA copied from one double strand of DNA
single stranded mRNA
cloverleaf shaped tRNA
To differentiate is to change. An example of cell differentiation is
a stem cell with no identity becoming a skin cell
a somatic cell going through mitosis
developing tissue in the tips of roots and shoots of plants
A and C
Cell cycle checkpoints are able to stop mutated cells. Mutated cells are cancerous. If the checkpoints are damaged, they are unable destroy (stop) cancerous cells from dividing. Compared to normal cell division,
cancer cell cycle is faster
cancer cell cycle is uncontrollable
cancer cell is continous
all of the above
Cancer cells are continually dividing. Because of this drugs used to treat cancer stop
protein synthesis
transcription
cell division
respiration

Recombination (crossing over) of genes in meiosis leads to
increasing genetic diversity
decreasing genetic diversity
increased growth rate of cells
decreased rate of cell wound healing
