How is transcription different in bacteria and eukaryotes Eu

How is transcription different in bacteria and eukaryotes? Eukaryotes require promoters, while bacteria do not require promoters. Eukaryotes have one RNA polymerase that transcribe all RNA, while bacteria have many RNA polymerases. Eukaryotes require rho protein for termination, while bacteria do not require rho for termination. Eukaryotic transcription occurs in a 5\' to 3\' direction, while bacteria transcription occurs in a 3\' to 5\' direction. Eukaryotes use general transcription factor for initiation, while bacteria use sigma factor for initiation. Which of the following elements is NOT found in mature mRNAs form bacteria? 3\' un translated region protein coding region 5\' un translated region promoter region Shine-Diagram sequence Suppose that a mutation occurs in the middle of a large intone of a gene-encoding a protein. What will the MOST likely effects of the mutation be on the amino acid sequence of that protein? The amino acid sequence would be the same, as this is a silent mutation in which the altered cordon encodes the same type of amino acid. The mutation may or may not affect the intone removal depending on whether nucleotides affecting splicing are altered. The amino acid sequence would be the same, as intones are removed during post-transcriptional processing. The protein would likely be altered significantly as all mutations have deleterious effects. The amino acid sequence would be the same, as this type of mutation results in substitution with a chemically similar amino acid.

Solution

The bacterial and eukaryotic transcription differ in many way. One of them is-

Bacterial RNA Polymerase requires Sigma factor for transcription initiation. Bacterial core RNA Polymerase composed of two alpha, one beta, one beta\' and omega subunits(core) and different sigma factor binds to it and initiate different sets of gene transcription.

While in eukaryotes transcription factors initiate transcription. Such as TFIIA, TFIIB, TFIID ,TFIIE, AND TFIIH
