What else can I help you with?
What molecule(s) cause(s) a portion of a DNA molecule to unwind for transcription?
During transcription, the enzyme RNA polymerase binds to the DNA at the promoter region, causing the DNA strands to unwind. This unwinding is facilitated by the breaking of hydrogen bonds between the complementary base pairs, allowing the DNA helix to open up and expose the template strand for RNA synthesis. Additionally, transcription factors play a role in this process by assisting RNA polymerase in binding and promoting the unwinding of DNA.
What chemical is an enzyme that add nucleotides to a new strand of DNA during replication?
DNA Polymerase is the enzyme which adds new nucleotides during replication.
What bonds do helicase and polymerase enzymes break?
Helicase enzyme breaks hydrogen bonds between base pairs in DNA strands to unwind the double helix structure. Polymerase enzyme breaks the bonds between nucleotides in the DNA strand being replicated, allowing for the addition of new nucleotides during DNA replication.
What enzymes are responsible for replication of the DNA molecule?
Helicase is the enzymes that splits the double helix into two separate strands, and DNA Polymerase (as opposed to RNA Polymerase) joins the nucleotides together in the new strands being created.
The process of DNA replication is completely controlled by what?
The process of DNA replication is controlled by various enzymes and proteins. Key players include DNA polymerase, helicase, and ligase. These enzymes work together to unwind the DNA double helix, separate the strands, and create new complementary strands.
What enzymes build DNA?
Enzymes involved in DNA replication include DNA polymerase, helicase, primase, ligase, and topoisomerase. These enzymes work together to unwind the DNA helix, synthesize new DNA strands, and repair any mistakes that may occur during the process.
Where does RNA polymerase bind?
RNA polymerase bind specific regions of DNA called promoters. The RNA polymerase holoenzyme is guided to promoters by interactions between members of the holoenyzme and specific DNA sequences such as the TATA box.
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.
How does RNA polymerase unwind DNA during transcription?
During transcription, RNA polymerase binds to a specific region of DNA and unwinds the double helix structure by breaking the hydrogen bonds between the base pairs. This allows the enzyme to access the DNA template strand and synthesize a complementary RNA strand.
What molecule(s) cause(s) a portion of a DNA molecule to unwind for transcription?
During transcription, the enzyme RNA polymerase binds to the DNA at the promoter region, causing the DNA strands to unwind. This unwinding is facilitated by the breaking of hydrogen bonds between the complementary base pairs, allowing the DNA helix to open up and expose the template strand for RNA synthesis. Additionally, transcription factors play a role in this process by assisting RNA polymerase in binding and promoting the unwinding of DNA.
Which which job must enzymes do before replication can begin?
Unwind part of the original DNA molecule :)
What chemical is an enzyme that add nucleotides to a new strand of DNA during replication?
DNA Polymerase is the enzyme which adds new nucleotides during replication.
Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?
DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.
Is DNA polymerase a protein?
Yes, DNA polymerase is a protein.
What enzyme transcribes DNA?
The enzyme that transcribes the DNA into RNA is called RNA polymerase.
What happens first at each origin replication?
Enzymes unwind DNA!
What are the key differences between DNA polymerase and RNA polymerase in terms of their functions and roles in the process of genetic information replication?
DNA polymerase is responsible for synthesizing new DNA strands during DNA replication, while RNA polymerase is responsible for transcribing DNA into RNA. DNA polymerase adds nucleotides to the growing DNA strand, ensuring accurate replication of genetic information. RNA polymerase reads the DNA template and synthesizes a complementary RNA strand. Overall, DNA polymerase is involved in DNA replication, while RNA polymerase is involved in transcription.
