Which enzyme is responsible for building the mRNA Strand?
RNA polymerase
Which enzyme is responsible for making mRNA and unwinding the helix during transcription?
In any case, upon binding, the RNA pol “core enzyme” binds to another subunit called the sigma subunit to form a holoezyme capable of unwinding the DNA double helix in order to facilitate access to the gene.
Which of the following enzyme is responsible for initiating DNA replication?
helicase
Which enzyme is responsible for facilitating?
Which enzyme is responsible for facilitating the hydrogen bonding between nucleotides in a new DNA molecule? Polymerase.
Which enzyme is not required for replication?
The conclusion that polymerase I is not required for replication implied that E. coli must contain other DNA polymerases, and subsequent experiments led to the identification of two such enzymes, now called DNA polymerases II and III.
What substrates are used in DNA synthesis?
What substrates are used in the DNA-synthesis reaction? dNTPs (deoxyribose nucleotide triphosphates)- which include a nucleotide (A, T, C, or G), a deoxyribose sugar and a triphosphate group. List the different proteins and enzymes taking part in bacterial replication.
What is the process called that converts the genetic information?
It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
What is the name given to the process in which the information encoded in a strand of mRNA is used to construct a protein?

How do mutations affect an organism?
How can mutations affect organisms? Mutations can affect an organism by changing its physical characteristics (or phenotype) or it can impact the way DNA codes the genetic information (genotype). When mutations occur they can cause termination (death) of an organism or they can be partially lethal.
What is a promoter?
A promoter is a sequence of DNA needed to turn a gene on or off. The process of transcription is initiated at the promoter. Usually found near the beginning of a gene, the promoter has a binding site for the enzyme used to make a messenger RNA (mRNA) molecule.
