The enzyme that is used to replicate DNA by adding new bases to the strand is called this.
What is DNA Polymerase

The makeup of DNA has the sugar deoxyribose. On the other hand, RNA has this type of sugar.
What is ribose
100
This is the term for a three letter sequence that specifies for a single amino acid during protein synthesis
What is a codon
100
This type of mutation is considered a substitution mutation, but when the base is changed, the amino acid remains the same
What is a silent mutation
200
The two sides of the DNA ladder are held together by these types of bonds
What is hydrogen bonds
200
On the tips of the chromosomes, the tips or ends of the chromosomes are called this.
What is a telomere
200
This type of RNA carries the DNA instructions to the ribosome for protein synthesis
What is mRNA
200
Proteins are formed by polypeptide chains, which are chains of this.
What are amino acids
200
If a nitrogenous base is inserted or deleted from the DNA or RNA strand, it results in this type of mutation.
What is a frameshift mutation
300
DNA is located in this X-shaped structure found in the nucleus.
What is chromosome
300
DNA replication involves using half the original strand as a template and adding new nucleotides to this existing strand. Because of this, DNA replication is referred to as this?
What is semi-conserative
300
In the Central Dogma of Molecular Biology, the process of going from to DNA to RNA is called this.
What is transcription
300
The tRNA carries the ________ which is the opposite of the codon found on the mRNA (number 5).
What is anticodon
300
Using the image of a chromosome, this represents what type of mutation?
What is inversion
400
According to the Base-Pair rule by Chargaff, if a DNA strand has 60% Thymine (T), then the same DNA strand will have this percentage of Adenine (A).
What is 60%
400
The original strand of DNA is as follows: A T T C G A. If the DNA is replicated the new strand would be this.
What is T A A G C T
400
This is the region of RNA where the RNA Polymerase binds to in order to begin transcription.
What is the promoter
400
True or False: The stop codon (ex. UAA, UAG, UGA) counts as an actual codon.
What is false. The stop codon just stops translation, but does not get added to the protein
400
A point mutation changes a codon from UAC to UAG. This would mean that the amino acid changes from _____ to ______.
What is Tyr to STOP
500
The structure of DNA, called a nucleotide, is composed of these three parts (list the parts)
What is sugar, phosphate and nitrogenous base
500
BONUS!! In DNA replication, the enzyme that unwinds the DNA before the DNA polymerase comes in to replicate the strand is called this
What is helicase.
500
Name the places where the following processes take place:
1. Transcription
2. Translation
1. What is nucleus
2. What is ribosome

In the image below, determine the structure for numbers 2 and 4.
What is...
2. Ribosome
4. tRNA

An original strand of DNA codes as:
A-T-C-G-G-A-C-T-T
Once mutated, the DNA reads as:
A-T-C-G-G-A-A-T-C-C-T-T
This represents what type of mutation?
What is insertion
