If a cell lacked the enzyme RNA polymerase, it could not synthesize RNA from a DNA template, which is essential for the process of transcription. This would prevent the cell from producing messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA), thereby disrupting protein synthesis and various cellular functions. Ultimately, the absence of RNA polymerase would hinder gene expression and the overall viability of the cell.

What enzyeme helps a cell to make a strand of rna?
RNA polymerase is the enzyme responsible for synthesizing RNA strands during transcription in a cell. It reads the DNA template strand and adds complementary RNA nucleotides to form an RNA strand.
Which of the following is an enzyme needed to connect new bases to a growing strand of DNA A Connexin B Lactase C DNA polymerase D Helicase?
DNA polymerase is the enzyme needed to connect new bases to a growing strand of DNA during replication. It catalyzes the addition of nucleotides to the growing DNA strand in a complementary fashion. Connexin is a protein involved in cell-cell communication, lactase is an enzyme that breaks down lactose, and helicase is involved in unwinding the DNA double helix.
How does Transcription take place?

What an example of an enzyme that builds a molecule?
DNA polymerase is an enzyme that builds DNA molecules by adding nucleotides to a growing DNA strand during DNA replication. This process is essential for cell division and the transmission of genetic information.
Where does transcription being in DNA?
Transcription begins in the nucleus of a cell, where the DNA molecule unwinds and the enzyme RNA polymerase binds to a specific region of the DNA called the promoter. RNA polymerase then synthesizes a copy of the DNA sequence into a messenger RNA molecule.
Which enzyme transcribes DNA into mRNA?
rna polymerase
What happens to a cell if it lack the enzyme DNA polymerase?
If a cell lacks DNA polymerase, it would not be able to replicate its DNA properly during cell division. This could lead to errors in the DNA sequence, potentially causing mutations and impairing the cell's ability to function correctly. Ultimately, this could result in cell death or contribute to the development of diseases such as cancer.
Enzyme that adds nucleotides to exposed nitrogen bases?
DNA polymerase is the enzyme responsible for adding nucleotides to exposed nitrogen bases during DNA replication. It catalyzes the formation of phosphodiester bonds between the incoming nucleotide and the growing DNA strand.
What enzyme carries out transcription in a eukaryotic cell?
There is no single enzyme responsible for the whole of transcription. Rather, there are many enzymes and supporting protein that collectively bring about transcription.The most important one is DNA dependent RNA polymerase
What is Major enzyme involved in replication?
DNA polymerase
What enzyme is coded forin the chromosome of bacteria?
One common enzyme coded for in the chromosome of bacteria is DNA polymerase, which is responsible for replicating the bacterial DNA during cell division. This enzyme is essential for maintaining the integrity of the bacterial genome.
What enzyeme helps a cell to make a strand of rna?
RNA polymerase is the enzyme responsible for synthesizing RNA strands during transcription in a cell. It reads the DNA template strand and adds complementary RNA nucleotides to form an RNA strand.
What enzyme matches RNA nucleotides to complementary DNA nucleotides?
The enzyme that matches RNA nucleotides to complementary DNA nucleotides is called reverse transcriptase. It is used by retroviruses like HIV to convert their RNA genome into DNA before integrating it into the host cell's genome.

Which enzyme is used in the synthesis of new copies of DNA?
In humans, many enzymes are involved in DNA replication. Among them are: DNA polymerase I DNA polymerase III Ligase Primase Helicase DNA polymerase I and III perform the bulk of the actual reproduction--their job is to add nucleotides to the growing strands. The others perform specialized functions and are essential to the process.
