What connects Rna nucleotides to dNA during transcription?
During transcription, RNA polymerase catalyzes the synthesis of an RNA molecule by base-pairing complementary RNA nucleotides with the DNA template strand. This complementary base pairing allows the RNA nucleotides to be connected to the DNA template, forming a growing strand of RNA that is identical in sequence to the non-template DNA strand.
Is DNA a single strand of nucleotides?
No, DNA is a double-stranded molecule composed of nucleotides. Each strand has a specific sequence of four different nucleotides: adenine, thymine, cytosine, and guanine. These two strands are connected by hydrogen bonds to form the double helix structure of DNA.
What enzyme is responsible for decodingthe DNA strand into an mRNA?
The enzyme responsible for decoding the DNA strand into an mRNA is called RNA polymerase. It catalyzes the synthesis of mRNA during transcription by matching complementary RNA nucleotides with the DNA template strand.
What molecule builds the new strand of RNA during transcription?
RNA polymerase builds the new strand of RNA during transcription. It catalyzes the formation of phosphodiester bonds between nucleotides to create the complementary RNA strand based on the DNA template strand.
Process of synthesizing an RNA strand from a DNA template strand?
During transcription, RNA polymerase binds to the DNA template strand and synthesizes a complementary RNA strand by adding nucleotides base-paired with the DNA template. The nucleotides are linked together, forming a single-stranded RNA molecule that is complementary to the DNA template. The process ends when RNA polymerase reaches a termination signal on the DNA template.

What is the enzyme that uses one strand of DNA as a template to assemble nucleotides into a strand of RNA?
RNA polymerase is the enzyme that uses one strand of DNA as a template to assemble nucleotides into a strand of RNA during transcription.
Is DNA a single strand of nucleotides?
No, DNA is a double-stranded molecule composed of nucleotides. Each strand has a specific sequence of four different nucleotides: adenine, thymine, cytosine, and guanine. These two strands are connected by hydrogen bonds to form the double helix structure of DNA.
What attaches free nucleotides to the growing DNA strand?
DNA polymerase attaches free nucleotides to the growing DNA strand during DNA replication. DNA polymerase catalyzes the formation of phosphodiester bonds between the nucleotides, incorporating them into the new strand complementing the template DNA.
How many strands of nucleotides does a molecule of RNA contain?
A molecule of RNA contains one strand of nucleotides.
Why RNA primers are needed during DNA replication and what is their fate?
RNA primers are needed during DNA replication to provide a starting point for DNA polymerase to begin building a new DNA strand. Once the DNA polymerase has extended the RNA primer with DNA nucleotides, the primer is removed and replaced with DNA by DNA polymerase. The fate of RNA primers is to be replaced with DNA, ensuring that the newly synthesized DNA strand is fully composed of DNA nucleotides.
What enzyme is responsible for decodingthe DNA strand into an mRNA?
The enzyme responsible for decoding the DNA strand into an mRNA is called RNA polymerase. It catalyzes the synthesis of mRNA during transcription by matching complementary RNA nucleotides with the DNA template strand.
What molecule builds the new strand of RNA during transcription?
RNA polymerase builds the new strand of RNA during transcription. It catalyzes the formation of phosphodiester bonds between nucleotides to create the complementary RNA strand based on the DNA template strand.
An okazaki fragment has which of the following arrangements?
An Okazaki fragment is a short, newly synthesized DNA fragment that is formed on the lagging strand during DNA replication. It is composed of a short RNA primer at the 5' end and DNA nucleotides that extend toward the replication fork.
Process of synthesizing an RNA strand from a DNA template strand?
During transcription, RNA polymerase binds to the DNA template strand and synthesizes a complementary RNA strand by adding nucleotides base-paired with the DNA template. The nucleotides are linked together, forming a single-stranded RNA molecule that is complementary to the DNA template. The process ends when RNA polymerase reaches a termination signal on the DNA template.
What is the name of the nucleotides have no DNA and no RNA?
Many viruses have nucleotides not found in DNA or RNA, such as Retroviruses like HIV that use reverse transcriptase to convert RNA into DNA for replication.
What enzyme adds nucleotides of RNA to make the mRna?
RNA polymerase is the enzyme responsible for adding complementary RNA nucleotides to the DNA template strand during transcription to create mRNA.
