Transcription is a process where the DNA converts into RNA. Enzymes used in the transcription is RNA polymerase which assembles the nucleotide in RNA by using DNA as a template. In prokaryotes the transcription takes place in three steps I.e. initiation, elongation, and termination. In eukaryot...
How is RNA therapy given? Why do retroviruses contain two identical RNA molecules? How do viruses get their DNA or RNA? How does RNA polymerase generate RNA without a primer? Why does DNA have to turn into RNA before it can make a protein? Why can't DNA just make the proteins itself?
Grossmann K: Why does DNA-dependent RNA polymerase I from higher plants possess a more complex subunit struc- ture than the enzyme from E.coli? A hypothesis. Plant Cell and Envir 6:1-3, 1983.Grossmann, K (1983) Why does DNA-dependent RNA polymerase I from higher plants possess a more ...

The mechanism of RNase H substrate recognition is proposed from a model of a chemically modified DNA-RNA hybrid Escherichia coli RNase H complex. Sitedirected mutagenesis of the enzyme and substrate titration observed by heteronuclear two-dimensional NMR spectra have been carried out. A model complex...
a unique DNA target but instead target a common sequence found in a family of genes. Such off-target effects could have negative outcomes on health. For example, if the guide RNA matches a gene that suppresses tumor growth, there is a risk that disabling it could turn the cell cancerous....
Instead, bits of the information from the DNA are copied into smaller, single-stranded molecules known asmessenger ribonucleic acid(mRNA). The mRNA travels out of the HQ and finds its way to the protein factory, which is the ribosome. In the ribosome, the instructions for amino acid attachmen...
DNA and RNA Glutathione (a critical antioxidant) Creatine (supplies energy to muscles) Why do we have to eat protein? Carbohydrates, fats and cholesterol are made of carbon, hydrogen and oxygen, but proteins are unique because they also contain nitrogen. This is why the body cannot make protei...
How an RNA virus could insert DNA copies into a host's cell? How can it have DNA as an RNA virus? Explain. What is the role of RNA? How does protein synthesis differ between prokaryotes and eukaryotes? Is the difference between RNA and DNA that the RNA duplicates itself in the cytoplas...
Why is DNA replicated into RNA, and why can't it be directly translated to proteins while there is only a base pair difference in DNA and RNA? Why is a beta-clamp used in DNA replication but not transcription? When does DNA synthesis occur???
