    Eukaryotic Transcription Inhibitors01:52

    Eukaryotic Transcription Inhibitors

    Certain biochemical processes, such as embryonic development and cell growth regulation, depend on the repression of specific genes. DNA binding proteins known as eukaryotic transcription inhibitors regulate the repression of gene expression in eukaryotes. The presence of these inhibitors at the required location and time in the cell is triggered by the presence of hormones and additional signals from other cells.
    Eukaryotic transcription inhibitors usually contain two distinct domains, a DNA...
    Transcription Attenuation in Prokaryotes02:42

    Transcription Attenuation in Prokaryotes

    Transcriptional attenuation occurs when RNA transcription is prematurely terminated due to the formation of a terminator mRNA hairpin structure.  Bacteria use these hairpins to regulate the transcription process and control the synthesis of several amino acids including histidine, lysine, threonine, and phenylalanine. Transcription attenuation takes place in the non-coding regions of mRNA.
    There are several different mechanisms used to attenuate transcription. In ribosome mediated...
    Bacterial Transcription01:53

    Bacterial Transcription

    RNA polymerase (RNAP) carries out DNA-dependent RNA synthesis in both bacteria and eukaryotes. Bacteria do not have a membrane-bound nucleus. So, transcription and translation occur simultaneously, on the same DNA template.
    Transcription can be divided into three main stages, each involving distinct DNA sequences to guide the polymerase. These are:
    Restriction Enzymes01:11

    Restriction Enzymes

    Restriction enzymes are bacterial enzymes used to cut DNA in a sequence-specific manner. To cleave DNA, they bind to specific palindromic sequences called restriction sites. Such palindromic DNA sequences or inverted repeats are commonly found in regions of functional significance, such as the origin of replication, gene operator sites, and regions containing transcription termination signals.
    The host bacteria protect their own genomic DNA from these enzymes by methylating these sites. Some...
