What is synthesized by RNA polymerase?
Polymerases are the enzymes that replicate and build nucleic acids. DNA polymerases synthesize DNA, RNA polymerases synthesize RNA. Purified polymerases are essential to carrying out the PCR reaction.
What is Teminism?
In 1963 Temin(name of the scientist) reported the theory in which certain RNA tumor viruses synthesize DNA, which in turn codes for protein. It is the process of formation of an intermidiate DNA on the body of a RNA inside the host cell to produce RNA of its own kind. Generally the process is going on in the body of genetic RNA found in some virus. The intermediate DNA is produce out , as the RNA do not have the capability to synthesize of its daughter RNA. the RNA is always synthesize out from DNA. It is somehow reverse of central dogma.
Why is RNA primase not DNA primase?
RNA primase is used to synthesize short RNA primers that are needed for DNA replication by DNA polymerase. This RNA primer can be easily replaced by DNA once DNA polymerase starts synthesizing the new DNA strand. This is different from DNA primase which synthesizes RNA primers during the synthesis of Okazaki fragments on the lagging strand during DNA replication in prokaryotes and eukaryotes.
Are both DNA and rna are involved in the central dogma of biology?
Yes, both DNA and RNA are involved in the central dogma of biology. DNA carries the genetic information from which RNA is transcribed. RNA, in turn, is used to synthesize proteins based on the instructions encoded in DNA.
How does RNA polymerase attach to unwound DNA during transcription?
RNA polymerase attaches to unwound DNA during transcription by recognizing and binding to specific promoter sequences on the DNA strand. Once bound, the RNA polymerase begins to synthesize a complementary RNA strand using the DNA template.
How does helicase contribute to the process of transcription?
Helicase unwinds the DNA double helix during transcription, allowing the RNA polymerase to access the DNA template and synthesize RNA molecules.
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.
The nucleus store the DNA needed to synthesize which molecule in the cytoplasm?
The nucleus stores the DNA needed to synthesize messenger RNA (mRNA) in the cytoplasm. mRNA carries the genetic information from the DNA in the nucleus to the ribosomes in the cytoplasm where protein synthesis occurs.
How does RNA polymerase utilize DNA during the process of transcription?
RNA polymerase utilizes DNA during transcription by binding to a specific region of the DNA called the promoter. It then unwinds the DNA double helix and reads the DNA template strand to synthesize a complementary RNA strand. This process allows the genetic information encoded in the DNA to be transcribed into RNA molecules.
How does reverse transcriptase work in the process of converting RNA into DNA?
Reverse transcriptase is an enzyme that can convert RNA into DNA. It does this by using the RNA as a template to synthesize a complementary DNA strand. This process is called reverse transcription and is important in the replication of certain viruses, such as HIV.
Retroviruses such as HIV contains what enzyme that enables DNA to be synthesized from rna?
Retroviruses such as HIV contain the enzyme called reverse transcriptase, which enables the synthesis of DNA from RNA. This DNA integrates into the host cell genome, allowing the virus to replicate and persist in the host.
What does DNA primase create?
DNA primase creates RNA primer. DNA primase is an enzyme and DNA polymerase uses the RNA primer to replicate ssDNA.
