What is the structure of DNA?
circular
double stranded or double helix
single standed
What is the role of DNA?
makes proteins from RNA
carries our genetic information, or directions to make proteins
translates RNA into amino acids
protects the cell from foreign invaders
In DNA A pairs with ____ and C pairs with ____
T, C
T, G
G, A
A, C
What would the opposite DNA strand look like based on the Strand: AATTCGGCA (Type the letters WITHOUT SPACES)
(a)
Which scientist(s) were credited in the discovery of the structure of DNA?
Watson
Crick
Wilkins
Franklin
Which scientists took photo 51, an X-ray chromatography picture of DNA?
Wilkins
Chase
Franklin
Crick
Why do cells need to replicate their DNA?
During cell division both new cells need a full set of DNA
they don't, most of our cells do not have DNA
it keeps DNA for getting damaged in a cell
What is a gene
a segment of DNA that codes for a particular protein
a section of RNA that codes for an amino acid
a chromosome that codes for multiple genes
A mutation that appears in the DNA
What is the purpose of RNA?
it is used to make proteins
used to edit our genetic code
used to carry our genetic code
Used to bond together amino acids
What is the role of Helicase in DNA replication?
it glues the pieces of copied DNA together
it builds the new DNA strand
it unzipps or sepertes the two strands of DNA
it lays down the RNA primer, so DNA replication can start
What is the role of DNA Polymerase in DNA replication?
it glues the pieces of copied DNA together
it builds the new DNA strand
it unzipps or sepertes the two strands of DNA
it lays down the RNA primer, so DNA replication can start
What is the role of topoisomerase in DNA replication?
it prevents the DNA from supercoiling or twisting back on itself
it unzips the DNA
It creates the new DNA strand
It lays down an RNA primer
What is the Central Dogma of Biology?
DNA --> DNA --> RNA
RNA --> DNA --> Proteins
DNA --> RNA --> Proteins
What is protein synthesis?
How our genetic code (DNA) with the help or RNA becomes proteins.
How RNA makes proteins all by itself.
How DNA is replicated during cell division.
Which of the following is not a type of RNA?
mRNA
cRNA
tRNA
rRNA
Which process describes Transcription?
RNA polymerase used the templete DNA strand to build mRNA, once the non coding sections have been removed the mRNA leaves the nucleus
The mRNA enters the ribosome and tRNA matches the mRNA codons with the correct amino acids, building an amino acid (or protein) chain
Which process describes Translation?
RNA polymerase used the tempplete DNA strand to build mRNA, once the non coding sections have been removed the mRNA leaves the nucleus.
The mRNA enters the ribosome and tRNA matches the mRNA codons with the correct amino acids, building an amino acid (or protein) chain
In RNA A pairs with _____ and C pairs with _____.
A-T, C-U
A-U, C-G
A-C, U-G
Use the DNA template strand to give the correct mRNA nucleotides : ATACCGGTAC (just type the letters no spaces!)
(a)
CCC codes for which amino acid?
(a)
GUU codes for which amino acid?
(a)
UAA codes for which amino acid?
(a)
A change in the genetic material of an organism is known as a ___________________.
Error
Mutation
Mistake
Nonsense
Which type of gene mutations result in a frameshift mutation? (More than one correct answer)
Substiution
Insertion

Which type of mutation only changes one amino acid in a protein?
Missense Mutation
Nonsense Mutation
Silent Mutation
What type of mutation is shown in Letter A
Inversion
Duplication
Deletion
Translocation
Which type of mutation can change a base of DNA but does not result in a different amino acid or protein?
Frameshift
Missense
Silent
Nonsense
