DNA dependent RNA polymerase is recruited by transcription factors on the promoter (TATA box) and starts transcribing mRNA from DNA by making a complimentary strand to the bottom strand in a 5' to 3' direction. Afterwards, the mRNA is capped with guanine-methyl, its introns are spliced out, and it's given a poly-A tail.
What else can I help you with?
Is there a template for transcribing original DNA to base sequence of RNA?
Yes, to transcribe DNA to RNA, replace thymine (T) in DNA with uracil (U) in RNA. Simply write down the complementary RNA bases to the DNA bases following this rule to transcribe the original DNA sequence to RNA.
What must happen to a DNA molecule before RNA polymerase can make RNA?
The DNA molecule must first unwind and separate into two strands. This process is called transcription, during which RNA polymerase can then read and transcribe one of the DNA strands to synthesize RNA.
Is H1N1 influenza a retrovirus?
No it is not. Retroviruses are RNA viruses that can change their RNA into DNA for cell infection (example HIV). Influenza viruses are also RNA viruses, but they do not transcribe the RNA into DNA. Some people think the R in RNA stands for retrovirus, but it stands for ribonucleic acid.
RNA can manufacture DNA via the action of what?
RNA can manufacture DNA via the action of reverse transcriptase, an enzyme found in retroviruses. Reverse transcriptase helps transcribe RNA into DNA by synthesizing a complementary strand of DNA based on the RNA template.
What enzyme is necessary for transcription?
The enzyme RNA polymerase transcribes DNA. This enzyme initiates transcription, joins the RNA nucleotides together, and terminates.
What must happen to a DNA molcule before RNA polymerase can make RNA?
Before RNA polymerase can make RNA, the DNA molecule must be unwound and the double helix separated to expose the sequence of nucleotides that will be used to transcribe the RNA. This process is facilitated by proteins that help open the DNA molecule for transcription.
What is the role of RNA polymerase in the synthesis of mRNA?
RNA polymerase is an enzyme that helps to transcribe DNA into mRNA by reading the DNA template and creating a complementary RNA strand. This process is essential for the synthesis of mRNA, which carries the genetic information from the DNA to the ribosomes for protein synthesis.
During interphase what form is the DNA?
During interphase the DNA is in loose form. It makes the chromatin inside the nucleus. The chromatin allow access to RNA and DNA polymerases that transcribe and replicate DNA.During interphase the DNA is in loose form. It makes the chromatin inside the nucleus. The chromatin allow access to RNA and DNA polymerases that transcribe and replicate DNA.
RNA polymerases are transcripted by which enzyme?
You seem confused. RNA polymerase is the enzyme that transcribes DNA into pre mRNA. So, the enzyme would transcribe the messenger RNA for its own protein construction.
RNA viruses are also called?
Viruses with RNA as their genetic material are called retroviruses. They use the enzyme reversetranscriptase to transcribe their RNA genome into DNA, which is then inserted into the host's genome.
What enzyme converts RNA to DNA?
The enzyme that converts RNA to DNA is called reverse transcriptase. This enzyme is commonly found in retroviruses and is utilized in the process of reverse transcription, where RNA is used as a template to synthesize a complementary DNA strand.
What virus DNA or RNA must supply its own enzyme to replicate or reproduce?
Retroviruses. They have genetic material of RNAand need the enzyme reverse transcriptase to transcribe a DNA strand from their RNA genetic material. Then another strand and then this is inserted into the hosts DNA to begin a lysogenic cycle.
