what enzymes is responsible for RNA synthesis

Expert Solution

Answer :

# Process of RNA synthesis from DNA is called transcription.While process of polypeptide synthesis from mRNA is called translation.

# In bacteria there are mainly three types of RNA a) mRNA - Provides codons which code for specific amino acids

b) tRNA - Reads codon by anticodon loop and brings required amino acid

c ) rRNA - Has structural and catalytic role during translation.

# There is single DNA dependent RNA polymerase that transcribes all types of RNA in bacteria. RNA polymerase on its own has capability of catalysing elongation process of transcription.It associates transiently with initiation factor to start transcription and termination factor to stop transcription.RNA polymerase uses nucleoside triphosphate as substrate and polymerises in a template dependent fashion following the rule of complementarity.

# But in eukaryotes we have three types of RNA polymerases in the nucleus all synthesising particular types of RNA as shown below

4. Glycogen Synthesis a) What is the role of Glycogenin in glycogen synthesis? b) Which enzymes regulate glycogen synthesis and degradation (directly or indirectly)? c) Hers disease is caused by mutations in the liver form of glycogen phosphorylase and often has mild symptoms. In contrast von Gierke disease, which is caused by mutations in glucose 6-phosphatase, has severe symptoms including severe hypoglycemia (low blood sugar). Based on your knowledge of glycogen and glucose metabolism, why does von Gierke disease have...

Although DNA and RNA synthesis have many shared features, there is a distinctive property in RNA synthesis which is absent in DNA. Which of the following is this? a. 5' to 3' direction of synthesis b. RNA polymerase can begin synthesis of a new RNA strand by first adding nucleoside triphosphate; DNA polymerase requires a primer sequence c. New strands are produced by using existing strands as a template d. Synthesis requires nucleoside triphosphates as a cellular supply

Transcription is the process of RNA synthesis. Translation is the cytoplasmic process of protein synthesis. Both processes can be divided into three stages, Initiation, Elongation, and Termination. For each of the events listed below write which process it occurs in (either transcription or translation) and in which stage the event occurs (initiation, elongation, termination). Release factor binds to the stop codon in the amino acyl site and cuts away the protein from the transfer RNA. Transfer RNA anticodons bind to the messenger...
