[RECALLS] Batch 2022 - 04/03/2019 Flashcards
Not true as process
Adenylation
Translation occurs on a complex of ribosomes called
Polysomes
Two strands are
Antiparallel
Concomitant with this denaturation of DNA is an increase in the optical absorbance of the purine and pyrimidine bases
Hyperchromicity
The message is read from 5’ to 3’ concluding with the formation of the carboxyl terminal of the protein
Polarity
Termination factor
Rho factor
Purine and pyrimidine are held by
Hydrogen bond
Unwinds the DNA
helicase
Identifies copying errors and corrects them
Proofreading
Adapters for the translation of info
tRNA
After splicing off the exons it becomes
Messenger RNA (mRNA)
Coding information can be changed at the mRNA level by
RNA editing
Yung addition din
Processivity
Correct sequence
Metaphase chromosome - Condensed loops - Noncondensed loops - 30 nm chromatin fibril - Beads on a string - Naked double helical
Transcription cycle
Template binding - Chain initiation - Promoter clearance - Elongation - Termination - RNA release
Consists of T-G rich sequences
Telomeres
Similar in RNA and DNA
Adherence to Watson-Crick base pairing
Enzyme responsible for the polymerization of ribonucleotides into a sequence complementary to the template strand of the gene is the:
DNA - dependent RNA polymerase
RNA polymerase I
rRNA
Transcriptionally inactive
Heterochromatin
Associated with activation or inactivation of gene expression
Acetylation
Associated with chromosomal assembly during DNA replication
Acetylation
Associated with the condensation of chromosomes during the replication cycle
Phosphorylation
Associated with DNA repair
ADP-ribosylation
Correlated with activation and repression of gene transcription
Methylation
Associated with gene activation, repression and heterochromatic gene silencing
Monoubiquitylation
Leads to transcription repression
Sumoylation
Correct transcription sequence of bacterial (Transcription cycle)
Template Binding Inititation Promoter Clearance Elongation Termination Release of RNAP
The enzyme responsible for the translation of information from the template strand of DNA to RNA
DNA-dependent RNA polymerase
Question about before and after RNAP
Topoisomerase
Removed
Introns
Spliced together
Exons
Description of pre-initiation complex
Step-wise assembly
