Listed below are steps in the transcription process. Reorganize the list so the steps in the correct order- starting with the first step in initiating transcription and ending with completion of a new strand of RNA (in other words- from start to finish of transcription). RNA polymerase reaches the termination signal DNA unwinds underneath RNA polymerase at transcription start site RNA polymerase is recruited to the promoter region mRNA transcript is released General Transcription factors bind TATA box (and other DNA sequences) in the promoter region General Transcription Factors unbind from promoter region mRNA transcript synthesis occurs RNA polymerase moves along the template strand in the 3’ to 5’ direction
Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
Listed below are steps in the transcription process. Reorganize the list so the steps in the correct order- starting with the first step in initiating transcription and ending with completion of a new strand of RNA (in other words- from start to finish of transcription).
- RNA polymerase reaches the termination signal
- DNA unwinds underneath RNA polymerase at transcription start site
- RNA polymerase is recruited to the promoter region
- mRNA transcript is released
- General Transcription factors bind TATA box (and other DNA sequences) in the promoter region
- General Transcription Factors unbind from promoter region
- mRNA transcript synthesis occurs
- RNA polymerase moves along the template strand in the 3’ to 5’ direction
Correct steps of Transcription are as follows.
1. General Transcription factors bind TATA box
(and other DNA sequences) in the Promoter region
2. RNA polymerase is recruited to the Promoter region.
3. DNA Unwinds underneath RNA polymerase at transcription start site.
4. RNA polymerase moves along the template strand in the 3 to 5 direction.
5. mRNA transcript synthesis occurs.
6. General Transcription factors unbind from promoter region.
7. RNA Polymerase reaches the terminal signal.
9. mRNA transcript is released
