Ch. 13 Vocab
The 3-dimensional structure of DNA.
What is a double helix?
RNA molecule that transfers genetic code messages from the nucleus to the ribosomes.
What is Messenger RNA (mRNA)?
Discovered the concept of transformation in bacteria.
Who is Griffith?
Number of strands.
What is two in DNA and one in RNA?
Monomer of proteins.
The process of duplicating DNA.
What is Replication?
Three consecutive bases that code for a specific amino acid.
What is a Codon?
Used bacteriophages to confirm that DNA is responsible for transformation.
Hershey and Chase
The base unique to DNA.
What is Thymine?
Start Codon sequence on mRNA
What is AUG?
The enzyme that adds new nucleotides and proofreads during replication.
What is DNA Polymerase?
The process of copying a DNA sequence into mRNA.
What is Transcription?
Discovered the 3D helix structure of DNA
Who are Watson & Crick?
The base unique to RNA.
What is Uracil?
mRNA sequence for the DNA sequence: T A A G C
What is A U U C G?
The process of changing one strand of bacteria into a different strand.
What is Transformation?
The process of building a polypeptide of amino acids from an mRNA template.
What is Translation?
First to identify DNA as the cause for bacterial transformation through the use of enzymes.
Who is Avery?
Sugar molecules.
What is Ribose in RNA and Deoxyribose in DNA?
Polymer of Proteins
What is a polypeptide?
The viruses that Hershey and Chase experimented with.
What are bacteriophages?
The three base sequence on a molecule of tRNA.
What is an anticodon?
Discovered that the percentage of A and T present in DNA are always the same.
Who is Chargaff?
Location in the Cell
What is the nucleus for DNA and the cytoplasm for RNA?
Anticodon for mRNA sequence UAG
