1.04 Bacterial Genetics Flashcards
The __ opens further the replication bubble
Helicase
The __ relieves the supercoiling of the double stand dna created by the unwinding of the strands
Topoisomerase
__ synthesize short RNA primers
DNA primase
__ are small DNA molecules that are physically separate from, and can replicate independently of chromosomal DNA
Plasmids
What is/are the products of mitosis
Two identical daughter cells
What are the products of meiosis
Four daughter cells with half the number of chromosomes of the parent cell
What are the two ways of propagation of bacteriophages
Lytic stage
Lysogenic stage
__ is the operon concerned with activation (control of promotor and repressor molecules)
lac operon
The __ operon is concerned with attenuation which can prevent the expression of the tryptophan gene when tryptophan levels are high
Trp operon
Homologous DNA recombination requires a set of _ gene
Rec gene (reciprocal transfer gene)
In bacterial DNA synthesis, the origin contains __ rich region which is recognized by the DNA binding protein DNAa
A-T rich region
What is the key enzyme used in polymerase chain reaction which synthesizes the complementary strands of DNA
Taq polymerase
