Describe the effects of mutating a sigma factor gene in bacteria. Drag the terms on the left to the appropriate blanks on the right to complete the sentences. Not all terms will be used. ResetHelp The core RNA polymerase enzyme . Since there are sigma factor genes, by mutating a single sigma factor gene there will be some that will not form which will affect transcription of .

Explanation:

Sigma factors bind to Ribonucleic acid polymerase (RNAP) which are required for bacterial RNA polymerase to recognize promoters. Bacteria have several types of sigma factors this is activated during different conditions.

Sigma factor identifies different classes of promoters and direct or regulate transcription to specific cellular programs they are called housekeeping sigma factor.

A mutation in sigma factor will affect transcription of bases this is because it binds with RNAP to initiate transcription of base sequence that should be moved to ribosome where it will be translated into an amino acid. This will further affect the growth of the bacteria.

many phylogenetic trees have a single lineage at the base representing a common ancestor. a lineage that evolved early from the root and remains unbranched is called basal taxon. when two lineages stem from the same branch point, they are called sister taxa.
