significance of having two different types of terminators in transcription? Transcription in prokaryotes is terminated by factors called rho-dependent and rho-independent terminators; Rho is a ring-shaped protein and is the main factor required for termination (Leland‚ 2010). The rho-dependent and rho-independent terminators play a major role in the separation of an RNA transcript from the DNA template which signifies the end of transcription. However‚ the exact process is not completely understood

In prokaryotes‚ it’s easier to make DNA replication because of the lack of a nucleus‚ but to do DNA replication in a eukaryotic cell is more difficult. DNA of an eukaryotic cell is in chromatin form to fit into the small nucleus for the replication to occur‚ first the DNA should open. This is because it is harder for eukaryotes to carry out DNA synthesis. Replication of DNA in a prokaryote is different from a eukaryote. In a prokaryote they have a single origin where the replication process starts

proteins‚ can be euchromatic or heterochromatic; euchromatin is mainly associated with active transcription‚ whereas heterochromatin is associated with repressed transcription. Active euchromatin and repressive heterochromatin are established by post-translational marks such as methyl groups placed on the histone around which DNA is wrapped. Histone 3 lysine 4 is methylated to promote active transcription‚ whereas histone 3 lysine 27 is methylated to promote the formation of facultative heterochromatin

widely studied. The interplay between the chromatin and transcription factors is very complicated (Angelini & Costa 2014). Chromatin is composed of DNA that is wrapped around nucleosomes to form domains of accessible (open) and inaccessible (closed) chromatin. The histone proteins regulate the chromatin accessibility. Accessible chromatin can facilitate association of transcription factors to DNA (Angelini & Costa 2014). Some transcription factors are capable of modifying the chromatin around their

in uncovering critical effects of transcription factors such as Phox2a‚ Phox2b‚ Hand2 and Gata3 on noradrenergic neurons. It is now well known that during the embryonic period‚ these transcription factors coordinately control the specification and differentiation of noradrenergic neurons. Recent years’ studies have shown that these transcription factors have a potential regulatory role of noradrenergic neurons in adult brains. For example‚ all four transcription factors are present in fully differentiated
