(a)Compare between DNA replication and transcription.Similarities1. Both involve unwinding of the double helix DNA;2.Both involve breaking of the weak hydrogen bonds between complementarbases;3.Both involve formation of phosphodiester bonds between neighbouring nucleotides;4.Both involve aligning free nucl...
Gene expression refers to the two processes, transcription and translation, that together use the information encoded in DNA to direct the synthesis of proteins. Ultimately, it is the proteins made in a given cell that are responsible for that cell's characteristics...
How can DNA be transcribed to RNA? Explain the function of: a. mRNA b. tRNA c. rRNA a) How is DNA transcription different than DNA replication/synthesis? b) What is the role of messenger RNA (mRNA) during DNA transcription? c) What happens to the mRNA after transcription is complete ...
How transcription factor regulate origins of DNA replication in eukaryotic cells. Trends Cell Biol 1993;3:161-7.DePamphilis ML (1993b) How transcription factors regulate origins of DNA replication in eukaryotic cells. Trends Cell Biol 3: 161–167...
DNA polymerases were named for their function of catalysing DNA replication, a process that is necessary for growth and propagation of life. DNA involving Watson–Crick base-pairing can be synthesized with high fidelity, the structural and mechanistic origins of which have been investigated for many...
Unspecific ssDNA degradation presents apotential harmful situation for the host cell since it could hinder basiccellular processes such as replication, transcription and DNA repair. Thisposes an important question: how could we eliminate this harmful indiscriminateactivity? As the cell cannot allow an in...
There may also be constraints on the activities of viral replication proteins such as the AIV polymerase which showed a significantly higher activity at 33 °C than 37 °C (Ngai et al., 2013). Only virus binding is considered here. Thus according to the Van't Hoff Isochore, the binding ...
Antiviral therapeutics used against COVID-19, target different stages of the virus life cycle from inhibition of viral binding to ACE2 receptors to virus transport and post-entry events such as replication, transcription, translation, and virus assembly and release. Among the antivirals that target...
Is RNA single-stranded? RNA gave rise to DNA, but how was RNA first formed? How is RNA converted into cDNA? How are RNA bases freed up during transcription to form base pairs? What is the unique nature of RNA? Is RNA involved at all in DNA replication?
How is transcription similar in bacteria and eukaryotes? How do proteins assist in DNA replication? In a prokaryotic cell, DNA is found where? How does DNA get turned into RNA? How does DNA replication cause variation? How would one study a ribosome cell?
