Is the enzyme that allows replication to occur DNA polymerase or RNA polymerase?

DNA polymerase replicated DNA. RNA polymerase creates mRNA to be used in protein synthesis. RNA polymerase does not replicated DNA.

Are mutations predictable?
No, they are random, This means that they occur in no set numerical order. So, though they can not be predicted it is certain, with the mistakes made in replication and other factors, that they will occur.
Are mutations in the DNA sequence gene transient changes?
Successful mutations will persist. Mutations usually occur during replication. Some mutations will flourish depending on environmental factors.
How does a genetic mutation occur when the mom and dad does not have one?
If something were passed down from parents, that would be inheritance. A mutation is when something goes wrong and causes a change in the genetic structure. Mutations can be caused by radiation or chemicals or mutations can also occur "naturally" when some part of DNA replication or correction goes wrong.
How is meiosis related to genes?
Meiosis allows a cell to form into 4 cells (by meiosis 1 (which is literally mitosis) and meiosis 2 (mitosis without DNA replication)) in meiosis 1, the cells exchanges DNA information between homologous pairs, this allows genes to be transferred and creates 4 unique and distinct cells. segragation of alleles occur too.
Where in the eukaryotic cell do replication transcription RNA processing and translation each occur?
In eukaryotic cells, you have a nucleus, whereas with prokaryotic cells you have none and you are missing some organelles found with the eukaryotes. Eukaryotes organelles are found within the cytoplasm.
What process must occur before mitosis and meiosis produces two identical dna strands from one original template and uses dna polymerase enzyme to produce the copy?
DNA replication
Which process must occur before mitosis and meiosis produces two identical DNA strands from one original templates and uses DNA polymerase enzyme to produce the copy?
DNA replication
What happens to a cell if it lack the enzyme DNA polymerase?
Transcription would be affected because the binding of the enzyme RNA plymerase to the promoter of the gene is the first step of transcription.
If an enzyme is absent during polypeptide production a mutation can occur?
This is a true statement. If an enzyme that is involved in DNA replication is not there, then a mutation can occur.
What will occur if a DNA polymerase makes a mistakeduring DNA replication?
It do occur during the replication. DNA polymerase has a proof reading activity that can correct the wrong base in the sequence. If the mutation persist it may cause any bad effect or stay neutral in case of silent mutation.
Which is the first step to occur during the process of replication?
Separation of the two DNA strands by the action of the Helicase enzyme.
How does mutations occur during DNA replication and transcription?
RNA polymerase doesn't have a proofreading function.
What enzymes help separate the two strands of nucleotides in DNA?
DNA Polymerase is the enzyme that seperates the two strands so that messenger RNA can read the genetic information of the DNA. The mRNA then moves two tranfer RNA so that Protien synthesis may occur.
What is the difference between the Helicase and DNA polymerase enzme?
The helicase in a way unzipps the wound DNA. DNA Polymerase then matches the nucleotide bases with free floating one so that A matches with T (or in RNA U) and G matches with C. Creating two new strands of DNA and completing DNA replication.
Can polymerase catch and correct every reptication error?
Yes. Initially, DNA replication makes 1 mistake in a 100,000. Like spell check, DNA polymerase comes in and removes errors in base pairs and correct them by adding the right ones. After DNA polymerase checks the new strand for errors, the end result is 1 mistake in a billion. If this didn't occur, mutations would surely take place in out body.
How errors in DNA replication are fixed?
Mismatch repair ... nucleotide excision repair
The sites where DNA replication and separation occur is called?
Both occur at the Replication Fork. Don't let the name deceive you.
