Scientists
The scientist(s) that discovered transformation in bacteria
What is Frederick Griffith
The role of 16S rRNA (ribosomal binding site)
What is it binds to Shine-Dalgarno site on mRNA for protein synthesis initiation & binds protein needed
BONUS = serves as a molecular clock for bacterial species when determine evolutionary distance among species
The description of Negative control Inducible Genes
What is the repressor is bound to the promoter region but once a inducer is present, the repressor is no longer bound & transcription can occur
The type of mutation where there is a change in the nuceoside sequence of codon but not the encoded amino acid
What is Silent Mutation
The definition of Attenuation
What is termination of transcription within the leader region (leader peptide)
BONUS: this was first demonstrated with trp operon
The scientist(s) that showed that the transforming substance is DNA
What is Oswald Avery and his colleagues
The role of 23S rRNA
What is it catalyzes peptide bond formation
The description of Positive Control Inducible Genes
What is the activator protein is not bound to the activator binding site but once a inducer is present the activator protein can bind & transcription can occur
The type of mutation where a single base substation occurs that changes codon for one amino acid into a codon for another amino acid
What is Missense mutation
The type of regulatory system used with the Trp Operon
What is Negative Control of Repressible Genes
The scientist(s) that discovered the complementary bases and antiparallel nature of DNA
What is James Watson, Francis Crick & Maurice Wilkins
The placement of the 16S rRNA and 23S rRNA on the ribosome
What is the 16S is a part of 30S subunit and 23S is a part of 50S subunit.
The description of Negative Control Repressible Genes
what is the repressor is not bound to the promoter region but once a corepressor is introduced the repressor can bind & transcription is stoped
The areas where Insertions and Deletions are most likely to occur
What is usually occurring in areas of repeated sequences where strand can become displaced
The function of restriction endonuclease
What is an enzyme that destroys viral DNA & in archaea and bacteria targeted through genetic engineering and are analogous to Innate Immune System
The scientist(s) that used X-ray crystallography to determine that DNA is a double helix
What is Rosalind Franklin
The two functional domains of the ribosome
What is translation domain which is on both subunits and exit domain
The description of Positive Control Repressible Genes
What is the activator protein is bound to the activator binding site but once a inhibitor is introduced, the activator protein is no longer bound & transcription is stoped
The type of mutation where a sense codon is converted to a nonsense codon
What is Nonsense Mutation
The description of Riboswitches
What is function in transcriptional termination in Gram Positive Bacteria & regulate translation of mRNA in Gram Negative bacteria
The scientist(s) that discovered Operons
What is Jacques Monod and Francois Jacob
The description of the peptidyl site
What is the donor site where it binds initator tRNA or tRNA attached to growing polypeptide (peptidyl-tRNA)
The type of regulatory system used with the Lac Operon
What is Negative Control of Inducible Genes
The function of the trp operon
What is it ONLY function in the absence of tryptophan and consists of 5 structural genes which code for enzymes needed to synthesize tryptophan
