(Blank)
what is the enzyme that breaks hydrogen bond/unwinds DNA?
Origin of Replication
Where does replication start?
Introns
What part of the mRNA strand is removed before it exits the nucleus? (non-coding)
AUG
What is the start codon in translation?
transcription
what is the process by which DNA is copied to RNA?
Nucleosome
DNA + 8 histones
The replication of DNA begins at one end of the molecule and proceeds to the other end.
True or false? If false, provide the true explanation.
False. DNA replication occurs simultaneously at many sites along the molecule speeding up the process of replication.
RNA polymerase
What enzyme is responsible for transcribing DNA into mRNA?
Polypeptide chain
During translation, the amino acids on tRNAs are bonded together to form what? Polypeptide chain
translation
what is the process by which RNA is "read" to make polypeptide chains
Phosphate group, sugar, and nitrogenous base
What are the three parts of a nucleotide?
Replicate this template strand of DNA:
TACTTACAAACCATAATT
ATG AAT GTT TGG TAT TAA
Used bacteriophages to demonstrate that DNA is the genetic material
Who were Hershey and Chase?
Anticodon
What is the sequence of 3 nucleotides on the tRNA called?
a process that includes fusing the nucleus from a fertilized egg with an adult cell with the genes inactivated to create an embryo
what is somatic cell nuclear transfer?
Ligase
What is the enzyme that joins Okazaki fragments together?
DNA Polymerase I
what is the enzyme that removes RNA primers and replaces them with DNA nucleotides
Scientist that used radiolabelled nitrogen to show that DNA replication was semi-conservative
Who were Meleson and Stahl?
molecular "scissors" that cut a specific sequences - usually a repeating sequence
what are restriction enzymes?
genetically engineering corn with a gene that provides protection from pests
what is genetic modification?
DNA polymerase III
What is the enzyme that adds nucleotides (in the 5' to 3' direction)?
semi-conservative
what is how DNA replicates?
Hydrolysis of deoxyribonucleoside triphosphate
What is the source of energy for incorporating nucleotides into the replicating DNA strand?
a method that separates DNA fragments based on size and charge
what is gel electrophoresis?
the level of protein structure determined by the amino acid sequence
what is primary structure?
