Week 5
In what direction does DNA replicate
What is " In the 5' to 3' direction"
Aqueous channels in the nuclear membrane that directly connect the nucleoplasm and cytosol
What are nuclear pore complexes?
A sequence of three nucleotides in mRNA that specifies a single amino acid
What is a triplet codon?
The position in a ribosome where tRNAs are released.
What is the (E)xit site?
The process of DNA being used as a template for its own replication.
What is semi-conservative replication?
What base pair replaces thymine for base pairing to Adenine in RNA
what is Uracil
The protein order that will be determined based on how the translation mRNA is read
What are translation reading frames?
Includes a 3' to 5' exonuclease to remove mis-incorporated nucleotides
Proof-reading
This repair pathway fixes accidental DS breaks in the DNA helix
What is non-homologous end joining?
A structure that is added to the 5' end of the mRNA transcript that is meant to prevent degradation of the polymer.
What is the methylated guanine cap?
What function does a molecular chaperone assist proteins with
What is protein folding
The process of linking the RNA polymerase, the enzyme that transcribes the DNA into RNA, as the first step of gene expression, to the repair of DNA damage
What is transcription-coupled repair?
DNA glycosylases that recognize a specific type of altered base in the DNA and catalyze its removal
What is base excision repair?
Used as the blueprints to assemble amino acids into proteins
What is mRNA?
The association of methionyl-tRNA, GTP, and eIF2 during translation initiation in eukaryotes.
What is a ternary complex?
Two pairs of strands: 1 crossing pair and 1 noncrossing pair
