What is the role of topoisomerase II?

Topoisomerase: are isomerase enzymes that act on the topology of DNAHelicase untwists the double helix and separates the template DNA strands at the replication fork. This untwisting causes tighter twisting ahead of the replication fork, and topoisomerase helps relieve this strain


What prevents knot formation in replicating DNA?

topoisomerases


What is an important role of RNA during transcription?

RNA play a vital role in Transcription, basically when DNA provide an information about synthesizing amino acid then Transcription occur. In transcription DNA unwind and mRNA synthesize through RNA polymerase. Intros are removed which are non coded region of DNA in nascent mRNA through splisosomes, and only Exon remains a coded region of DNA. In simple DNA dictates to mRNA about specific protein structure.


What role do mitochondria have in transcription?

Mitochondrial DNA is DNA found in the mitochondria that converts chemical energy from food into ATP for energy. This energy is then used in transcription, along with the other cell functions.


What role does transcription play in protein systhesis?

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis.


What DNA begins to uncoil DNA?

DNA helix uncoils the DNA for transcription to occur.

Process of synthesizing an RNA strand from a DNA template strand?

The synthesis of mRNA from DNA is called transcription.

Does transcription occur in DNA or RNA?

Transcription occurs in DNA to produce mRNA.

What is an exon's role in DNA?

The exon codes for the opening sequence of DNA for protein synthesis. It is a sequence of nucleotides that code for the RNA to begin transcription of the DNA to RNA protein.
