DNA/RNA Structure
The building blocks (monomers) of DNA and RNA
Nucleotides
This enzyme is responsible for separating the DNA strands by breaking the hydrogen bonds which hold base pairs together.
Helicase
3 bases in a row on the tRNA that compliments the codons found on the mRNA.
Anticodon
Point Mutations can substitute a base or shift the entire frame. Which type of substitution changes the amino acid to a STOP codon?
Nonsense
What type of sugar is found in RNA?
Ribose
What type of bond holds the nitrogen bases together?
Hydrogen bond
DNA Replication is said to be ______________ because it contains one old and one new strand.
Semiconservative
Type of RNA molecule that brings/carries amino acids to the ribosome.
tRNA
A type of substitution that results in only one amino acid changing.
Missense
DNA & RNA are both examples of what type of macromolecule found in our body?
Nucleic Acids
What nitrogen base is not found in RNA?
Thymine
During DNA Replication, what base bonds with Adenine?
Thymine
On what organelle does translation take place?
Ribosome
What are the two types of frameshift mutations?
Insertion and Deletion
Where in the cell does Transcription take place?
Nucleus
What two nitrogen bases are purines?
Adenine and Guanine
If C & G make up 30% of the DNA, how much of the DNA is composed of Thymine?
35%
Determine the amino acid sequence for the following mRNA sequence: AUG CUA AUA GCG UAG
Met-Leu-Ile-Ala-Stop
A chromosomal mutation that occurs when part of the chromosome breaks off and attaches to another chromosome.
Translocation
What nitrogen base bonds with cytosine?
Guanine
What molecules make up the backbone of the DNA strand?
Sugar & Phosphate

AAT GGC CGA TAC
Determine the mRNA sequence if given the DNA sequence GAG CGA TAG TTA
CUC GCU AUC AAU
A random change in the nucleotide sequence in DNA.
Genetic Mutation
What are the building blocks of proteins?
Amino Acids
