DNA Replication/ Repair/ Recombination
Most accurate form of double stranded break repair
Homologous recombination
The sequence of 3 nucleotides on mRNA that specify a single amino acid.
What is a codon?(It is complementary to the anticodon on the cloverleaf shaped tRNA’s middle loop)
This molecule carries genetic information from DNA to the ribosome and serves as the template for protein synthesis.
What is mRNA?
Transcription Factor that recruits RNA polymerase II to promotor (BRE element sequence recognition)
General Transcription Factor II
The enzyme that joins DNA fragments together, (Okazaki fragments) on the lagging strand.
What is DNA ligase? (not DNA Pol who instead can extend a primer)
This enzyme unwinds the DNA double helix at the replication fork by disrupting the hydrogen bonds between complementary bases.
What is helicase?
Charges tRNA with their specific amino acid during protein synthesis.
aminoacyl-tRNA synthase
The first enzyme involved in BER (base excision repair)?
What is DNA glycosylase? (It recognizes and removes the damaged base)
During transcription, this enzyme reads the DNA template strand and synthesizes a complementary RNA strand in the 5′ to 3′ direction.
What is RNA polymerase?
Using energy from ATP hydrolysis these proteins allow newly synthesized proteins to obtain their optimal 3-D configuration.
Molecular Chaperones
Which 2 enzymes are used in both replication and repair?
What is DNA polymerase,and DNA Ligase?
(DNA pol can synthesize DNA to match the template, Ligase can repair breaks)
During translation, these three RNA codons signal the ribosome to terminate protein synthesis.
What are UAA, UAG, and UGA?
