What enzyme is needed in order for transcription to take place?
RNA polymerase is the enzyme needed for transcription to take place. It catalyzes the synthesis of an RNA molecule from a DNA template.
What is the catalytic region of enzyme?
The catalytic region of an enzyme is the place where substrate molecules bind and undergo a chemical reaction.
What does the first nucleotide attach to because DNA polymerase can only add nucleotides to a pre-existing strand?
A primer molecule is required for DNA polymerase to initiate the addition of nucleotides. This primer provides a starting point for DNA polymerase to begin adding nucleotides in the correct sequence. Once the primer is in place, DNA polymerase can add nucleotides complementary to the template strand.
What are reactants that enter enzyme-controlled reactions?
Reactants that enter enzyme-controlled reactions are typically substrates. Substrates are the specific molecules that enzymes act upon to catalyze a biochemical reaction. The enzyme binds to the substrate at the enzyme's active site, where the reaction takes place.
Which type of the following is NOT required for a polymerase chain reaction (PCR) to Occur?
In a polymerase chain reaction (PCR), the key components required include DNA templates, primers, nucleotides, and a DNA polymerase enzyme. However, one component that is NOT required for PCR to occur is a living cell, as the reaction can take place in vitro (outside of a living organism).
What is the active site for an enzyme?
The place where the substrate and the enzyme meet to allow the enzyme to function.
What is the place where the substrate attaches to the enzyme?
The active site is where the substrate binds to the enzyme. It is a region on the enzyme where the chemical reaction takes place. The active site is specific to the substrate molecule, allowing for precise catalysis to occur.
What is the active site of an enzyme?
The most important part of the enzyme- where the chemical reactions happen. Substrates fit into the active site and are broken down or catalysed into end products (this is called the lock and key model).
How many nucleotides are needed to 'read' or place a single amino acid?
Three.
What is the name given to the part of an enzyme where the substrate comes into contact it?
The active site is the specific part of an enzyme where the substrate binds and interacts with the enzyme. This is where the chemical reaction facilitated by the enzyme takes place.
What is DNA-replication?
DNA replication is a process during which DNA double helix opens like a zipper , new nucleotides are added along both strands of DNA by enzyme DNA polmerase and at last two molecules of DNA are formed. It takes place in S phase of interphase .
What else can effect how an enzyme works by changing the enzyme's shape can the reaction still take place?
invalid question!
What enzyme is needed in order for transcription to take place?
RNA polymerase is the enzyme needed for transcription to take place. It catalyzes the synthesis of an RNA molecule from a DNA template.
What is the difference between enzyme and active site?
An enzyme is a protein that catalyzes a specific chemical reaction. The active site is a region on the enzyme where the substrate binds and the catalytic reaction takes place. The active site is crucial for the enzyme to function properly and interact with its substrate.
Nucleotides are comprised of what?
Nucleotides contain a 5-carbon sugar, phosphate, and one of four nitrogen bases; adenine, thymine, guanine, cytosine, and uracil in place of thymine in RNA.
What the definition of Substrate?
The reactants of enzyme-catalyzed reactions. Or, A substance with which a enzyme binds itself and form a complex product, a chemical reaction takes place between enzyme and substrate.
What is the name of the place where an enzyme and substrate attach?
the active point
