What is the role of the enzymes in cloning?
The role of arestriction enzyme is to remove the intronsto make a mature mRNA, so that the new mRNA codes for the making of a single protein. The restriction enzyme will only leave the exons to make the mRNA more shorter, and therefore easier to insert into plasmids
What unwinds a segment of DNA to make mRNA?
an enzyme (i answered my own question ha ha! progress!)
What is the three nucleotide?
Messenger RNA (mRNA) serves as the primary transcript, and its nucleotide sequence determines the amino acid sequence of proteins. A codon in mRNA comprises of three nucleotides that encode a specific amino acid. For example, the codon for glutamine is CAG (Cytosine, Adenine and Guanine). The most common stop and start codon is TAA and AUG respectively.
How many tRNA nucleotides form an anitcodon that will attach to the mRNA codon?
The codon and the anticodon interact with each other via hydrogen bonding, hence both the codon and anticodon are made up of the same number of nucleotides, which is three.
What determines the type of protein that is produced in protein synthesis?
This could be answered a few ways, but at the most specific, it is the codons that are translated via tRNA which make a protein. Each codon, represented by 3 nucleotides, "codes" for an amino acid. A string of amino acids make a protein, thus the nucleotides in the codons determines the product. To get to this point, requires transcription from DNA into mRNA and then mRNA is translated into the amino acids, so you could say that DNA itself determines the protein produced; however, it is actually the codons in the mRNA that are used to make the protein. The section of DNA that is transcribed is called a gene, so you could also say that it is the gene that determines what is produced.
Is DNA a type of enzyme that puts together amino acid to make a protein?
DNA is not an enzyme. DNA does not make proteins. tRNA translates DNA into RNA. mRNA moves the RNA from the nucleus to the cytoplasm (only in eukaryotes, prokaryotes do not have a nucleus). mRNA is then translated by tRNA. tRNA puts the nucleotides together to form a peptide chain that refolds and becomes a protein.
Where does the messenger RNA have to travel to after transcription?
The process wherein messenger RNQ (or mRNA) is given a message is called transcription. In this process, n mRNA molecule is made (or transcribed) using DNA as the template. Essentially, the nucleotide sequence on a gene is read by an enzyme called RNA polymerase which synthesizes the mRNA molecule. Put simply, RNA polymerase scans the length of DNA until a gene is encountered. When the enzyme reaches the correct position, it begins adding complimentary nucleotides to make the mRNA molecule. This way, the entire gene is transcribed and copied on to the mRNA molecule.
What is the name of the enzyme that copies the sense strand to make mRNA?
RNA polymerase

How does the cell know which enzyme to make and how to make it?
Enzymes are proteins. Thus, DNA codes the enzyme's information to an mRNA strand, which then is translated by tRNA into an anticodon. This takes place on the ribosome.
What enzyme attaches new DNA nucleotides to make the new strand of DNA?
DNA polymerase
How do amino acids make up protines?
Through a process called translation. The mRNA travels from the nucleus to the cytoplasm and binds to a ribosome. The sequence of 3 nucleotides in the mRNA correspond to a certain amino acid that binds to the top of the ribosome and then the mRNA keeps getting read, 3 nucleotides at a time, until there are 20 amino acids binded together. The ribosome then lets the protein go.

When a Cell needs to make a certain protein it gets the directions from the nucleotides located in?
Messenger Rna: mRna is fed linearly into the protein manufacturing complexes known as Ribosomes.
What is the process by which DNA is used as a template to make more DNA?
The double strand is separated by an enzyme called helicase. A primer is placed at the 3' end of the template strand. DNA Polymerase III (another enzyme) then adds new nucleotides to the primer, in the 5'-3' direction. The primers are replaced with DNA nucleotides by DNA Polymerase I and joined together by ligase. This is how DNA is replicated.
What is made up of three adjacent nuclotides and is responsible for directing the adding of a particular amino acid to a polypeptide?
Three adjacent nucleotides make up one codon of mRNA.
