Flashcards in Exam 2 Prep Deck (27):
As DNA replicates, it's using the original double helix and unzips and creating a old strand and a new strand using the parental strands as a template.
What is the Product of Transcription?
Where is the Transcription occurring?
Where does the Translation occur?
During transcription of a particular gene, the RNA polymerase will transcribe?
Only one DNA strand in the 3' to 5' direction
Group 2 introns, nuclear pre mRNA share this mechanistic feature of splicing?
Initiation of the phosphate ester bond, exchanged by 2'OH of branch point Adenosine
DNA Methylation of gene
inhibits transcription by making DNA inaccessible
Which enzyme decodes nucleotides to amino?
Amincoacyl tRNA synthase
Which of the following best describes the 'cap' mod to mRNA?
Modified Guanine to 5' end.
Where does the ribosome production occur?
in the area of nucleolus
Consequences of semi-conservative replication
Inheritance of genetics
RNA Polymerase differ from DNA Polymerase in which feature?
Only DNA polymerase require a primer nucleotide
Function of the 5' cap
prevents degradation from the 5' end
transports out of the nucleus
initiation of translation
Modified or suppressed genes
involved in transcription, participates in active transcription from DNA to mRNA
Where is mRNA is located...
in the Nucleus
enzyme that catalyze the formation of RNA from DNA (RNA Polymer)
codes for a different amino acid
stops the code early by a mutation of a termination code
has no effect on the code
synthesis of RNA primers
Breaks the hydrogen bonds between strands
releases the winding strain
binds to the single strand to prevent the return of the Hydrogen bonds
clamps the polymerase to the DNA strand
Seals the dna strands
