What type of bond holds the bases together in the DNA double helix? hydrogen bonds
What is the enzyme used during transcription that will unwind DNA and add nucleotides to create a mRNA strand? RNA polymerase
What is the process name for when the mRNA strand is used to make a protein? Translation
Scientist who determined that transformation from Griffith’s experiment was probably due to DNA being the genetic material. Avery
What type of mutation has DNA bases switching places? Inversions
What is the enzyme that unwinds the DNA during replication? DNA helicase
What are the 3 parts of a nucleotide? sugar, phosphate, base
If an original DNA is represented as: 12345 And the mutated one is represented as: 126345 What type of mutation is this? Addition

After transcription the mRNA leaves the ______ and goes to the __________. nucleus, ribosome
Using a codon chart, what is the amino acid associated with: AGU ser
Are all mutations harmful? no, some have no change, some are beneficial
Scientists who verified using radioactive labeling and bacteriophages to determine that DNA definitely was the genetic material and not protein. Hershey & Chase
Scientist who used S. Pneumonia and found that something changed a non-harmful strain into a harmful strain. Griffith
What is the enzyme that will put strands together during replication? DNA ligase
This type of category of mutations are when the multiples of 3 (codons) change. Frameshift mutation
What type of RNA molecule has an amino acid attached and carries them to the ribosome? tRNA

What are the 3 bases called on a mRNA strand? codon
What is the enzyme that will add nucleotides and proofreads during replication? DNA polymerase
Scientist who determined that the same amount of adenine equals the same amount of thymine in DNA, and cytosine is same amount as guanine Chargaff
What is the process name for making mRNA from a DNA gene? transcription
This type of category of mutations are based upon a single base pair change. Point mutations
Scientist who created the famous photo 51? Franklin
