Final Round
Slide A1
Gametes (sperm or egg) are produced by
this process
What is Meiosis?
Back
Slide A2
Meiosis produces these types of cells
What are four genetically different haploid
cells?
Back
Slide A3
This is the number of chromosomes in a
gamete
What is N?
Back
Slide A4
When homologous chromosomes line up
and exchange portions of their “arms” it is
called this
What is crossing-over?
Back
Slide A5
Homologous chromosomes are separated
during this phase of Meiosis.
What is Anaphase I?
Back
Slide B1
DNA is composed of these three
molecules.
What is Deoxyribose, a phosphate group,
and a base?
Back
Slide B2
This molecule “unzips” the DNA molecule
in preparation for DNA Replication.
What is DNA Polymerase?
Back
Slide B3
In order for DNA to “unzip” these two
events must occur.
What are the breaking of hydrogen bonds
between the base pairs and the
unwinding of the DNA strands?
Back
Slide B4
DNA replication results in two strands,
each with these.
What is one original strand and one new
strand?
Back
Slide B5
If this DNA strand was the template for
DNA replication, the resulting DNA strand
would be . . .

Slide C1
The process in which an RNA strand is
made based off a DNA template
What is Transcription?
Back
Slide C2
The molecule that directs mRNA
synthesis
What is RNA Polymerase?
Back
Slide C3
This is where transcription takes place.
What is inside the nucleus of a cell?
Back
Slide C4
These are the three components of an
RNA nucleotide.
What are Ribose, a phosphate group, and
a base?
Back
Slide C5
These are the four main differences
between RNA and DNA.
What are single vs. double strands, Uracil
vs. Thymine, Deoxyribose vs. Ribose, and
the ability to leave the nucleus vs. not
leaving the nucleus?
Back
Slide D1
This process uses information from
mRNA to make proteins.
What is translation?
Back
Slide D2
These contain information for making
proteins.
What are genes?
Back
Slide D3
These types of RNA are involved in
protein synthesis.
What are mRNA, tRNA, and rRNA?
Back
Slide D4
This RNA molecule carries amino acids to
the ribosomes.
What is tRNA?
Back
Slide D5
This causes translation to stop.
What is a stop codon?
Back
Final Round
This codes for one amino acid.
What is a codon?
