The correct order of these steps in the life cycle is a v vi

The correct order of these steps in the life cycle is. a. v, vi, ii, iv, i, and iii. b. v, ii, vi, i, iv, and iii. c. ii, vi, i, iv, iii, and v. d. v, ii, i, iv, vi, and iii. Of the following, which could not be considered a replicon. a. bacteriophage. b. transposon. c. plasmid. d. satellite virus. According to the Central Dogma of molecular biology a. RNA is translated from a DNA template then transcribed. b. Proteins arc transcribed at same time they are translated. c. The flow of information is from DNA to RNA to protein. d. Reverse Transcriptase is used to remove introns from RNA. Transcription begins when a. RNA polymerase find a 3\' UTR. b. When the first AUG in a template is recognized. c. An open reading frame is discovered. d. RNA polymerase recognizes a promoter sequence, binds to the DNA, and synthesizes the 5\' end towards the 3\' end of the new piece. The lac operon is an example of both specific regulation and global locus is diagrammed below with promoter and structural genes for lacl, lacZ, lacY, and lacA, in Other regions of DNA are labeled a., b., and c. Please use the diagram and these labeled region. Answering questions 11-13. The operon is kept off in the absence of lactose by: a. lacl protein binds to the region labeled b., and prevents the binding of RNA polymerase promoter. b. Allolactose is not available to bind to region a. Therefore RNA polymerase cannot translate the lacl gene. c. Lacl protein binds to region labeled c. and preventing binding of RNA polymerase. d. Allolactose binds to lacl protein which allows it to bind to region labeled c. preventing transcription.

Solution

Which could not be consider a replicon

Answer= b] Tranposon

Explaination =

Replicon = It is DNA molecule or RNA molecule or a region of DNA or RNA that replicates from a single origin of replication

Generally plasmid & bacteriophages replicated as single replicon

Satellite viruses are also replicon

Transposon =is a DNA sequence that can change its position within a genome

there are 2 mechanisms of transposition replicative & conservative
