DNA
The monomer, or sub unit, of DNA.
Nucleotide.
The monomer, or sub unit, of DNA.
Nucleotide.
Where does DNA replication occur within the cell?
The nucleus.
Where does transcription occur in the cell?
The nucleus.
What organelle is the primary location for translation within the cell?
The ribosome.
A DNA nucleotide consists of a phosphate group, a nitrogenous base, and a 5-carbon sugar called
deoxyribose.
A RNA nucleotide consists of a phosphate group, a nitrogenous base, and a 5-carbon sugar called
ribose.
During replication, this enzyme unzips and unwinds the parent DNA.
Helicase.
mRNA.
A sequence of 3-mRNA bases is called a
codon.
What rule states that adenine is paired with thymine, and guanine is paired with cytosine.
The base-pair rule.
What base replaces thymine in RNA?
Uracil.
Because daughter DNA is made of 1/2 new DNA, and 1/2 parent DNA, the replication process is described as being
semi-conservative.
What is the key enzyme of transcription?
RNA polymerase.
1 codon =
1 amino acid.
What is the general shape of a molecule of DNA?
Double helix.
Single-stranded.
During replication, this enzyme adds complementary bases to the template DNA.
DNA polymerase.
If the following code is "read," in the DNA, what would be the complementary mRNA?
TTAGC
AAUCG
The final product of transcription is
a peptide (polypeptide/protein).
What is the general function of DNA?
To store and transmit genetic information.
What are the three types of RNA?
Messenger RNA, Ribosomal RNA, Transfer RNA (mRNA, rRNA, tRNA).
Okazaki fragments.
After the mRNA is synthesized, it is edited and these are removed from the original mRNA (pre-mRNA).
Introns.
What pairs with the codon that guarantees the correct amino acid is being used?
The anticodon (on the tRNA).
