What enzyme is necessary for transcription?
The enzyme RNA polymerase transcribes DNA. This enzyme initiates transcription, joins the RNA nucleotides together, and terminates.
How do repressors affect promoters?
a repressor is a protein that binds to DNA, which turns off the genes that code for the digestive enzymes. the promoter, located near the digestive enzyme genes, is a section on DNA that serves as the binding site for the enzyme RNA polymers.
What are four types of chromosomal mutations?
Four types of chromosomal mutations are Down syndrome (which is a mutation in which there are three copies of chromosome 21), Kinefelter Syndrome (which is a mutation in which a male has an extra X-chromosome), Turner Syndrome (which is a mutation in which a female is missing an X-chromosome), and Patau Syndrome (which is a mutation in which there are three copies of chromosome 13).
Do The actions of DNA binding proteins help to determine whether a gene is turned on or off?
Yes, DNA binding proteins can influence gene expression by binding to specific sites on the DNA and either promoting or inhibiting gene transcription. These proteins can act as activators to enhance gene expression or repressors to suppress gene expression, thus controlling whether a gene is turned on or off.
What describes a DNA mutation?
An error occurs when the damaged DNA is repaired.an error occurs when the damaged DNA is repaired

When a section of the DNA of the genetic code is altered as a result of a toxin it is refeffered to as a?
Mutation.
What is necessary for transcription?
DNA polymerase is the enzyme that "unzips" the complementary DNA strands allowing mRNA to transcribe, or copy, a section of DNA.

What molecule helps code the DNA?
lets take this section of DNA ATAGCCATA DNA polymerase codes for the antisense (not mirror) strand. this would be TATCGGTAT
Where can someone buy a plastic binding comb?
One can buy a plastic binding comb in a variety of places. The best and first place to look would be at a local personal care shop, or section of a supermarket like Target or Walmart.
What is the doctrine of binding precedent Australia law?
Essentially binding precedent means that if a higher court has ruled on what is substantially the same legal issue, then that ruling is binding on the lower courts. This is designed to build up a consistent body of law, so for example, we dont have 30 different interpretations of 1 section of statute.
How are cultures affected by outside influences (from Globalization Section 1)?
It depends what the outside influence is.
What describes a DNA mutation?

How does RNA polymerase know where to start transcribing a gene into mRNA?
The enzyme that synthesizes RNA (RNA polymerase) binds specific DNA sequencesthat typically lie before the gene being transcribed. When everything it needs to start synthesis is properly assembled (any cofactors, etc.), only then can it begin transcribing DNA into RNA.
