This the the base pairing rule determined by Erwin Chargaff.
What is Adenine (A) = Thymine (T) while Cytosine (C) =Guanine (G)?
100
This is the location in which DNA replication takes place.
What is the nucleus?
100
Two answers: This is the location in which transcription takes place. This is the location in which translation takes place.
What is the nucleus? What is the ribosome?
100
These are the four nitrogen bases found in an RNA molecule.
What is Adenine (A), Uracil (U), Cytosine (C), Guanine (G)?
100
This is a change in the DNA sequence, altering the genetic information.
What is a mutation?
200
This is the shape of a DNA molecule which was determined using Rosalind Franklin's Photo 51. It is also often described as a "twisted ladder."
What is the double helix?
200
This is the enzyme responsible for unwinding and unzipping a molecule of DNA in preparation for replication.
What is DNA Helicase?
200
If a DNA sequence is TAC GGC ATT, this is the complementary mRNA sequence created following transcription.
What is AUG CCG UAA?
200
This RNA molecule contains complementary anticodons which ensure that the correct amino acid is added to the polypeptide chain.
What is tRNA or transfer RNA?
200
This type of mutation may or may not affect the amino acid sequence of a protein and involves the substitution of one single nitrogen base for another.
What is a point mutation?
300
If one strand of DNA is C A T G G A, then this is the complementary DNA sequence.
What is G T A C C T?
300
This is the model which states that each original strand of DNA serves as a template for the new, complementary strand.
What is the semiconservative model?
300
This is the enzyme responsible for adding complementary nucleotides in order to the molecule of mRNA during transcription.
What is RNA Polymerase?
300
These are the three types of RNA which are all involved in the making of proteins.
What is mRNA, rRNA, tRNA?
300
This type of mutation occurs when a base is added or deleted from DNA. It alters the "reading frame" of the mRNA codons, therefore changing the following sequence of amino acids.
What is a frameshift mutation?
400
DNA is a polymer made up of repeating units, or building blocks, called this.
What are nucleotides?
400
This is the enzyme responsible for constructing the new strand of DNA during DNA replication.
What is DNA Polymerase?
400
In this process, mRNA codons are used to signal specific amino acids in the building of a protein.
What is translation?
400
This is number of CODONS found on an mRNA molecule to signal five amino acids.
What is five codons?
400
Original DNA: TAC TTG GCA GGG
Mutated DNA: TAC TTT GCA GGG
The above is an example of this type of mutation?
What is a point mutation or substitution?
500
Watson and Crick helped determine that these are the three components of a DNA nucleotide.
What is 1. sugar (deoxyribose)
2. phospate
3. nitrogen base
500
This is the stage of the cell cycle in which DNA replication takes place.
The S stage of Interphase.
500
This is reached and indicates that a protein is complete.
What is a stop codon?
500
This is the RNA molecule which brings the amino acids to the ribosome.
What is transfer RNA (tRNA)?
500
The protein will be incomplete if a mutation causes this to appear too early in the genetic sequence.
