Where do you find the nucleotides?
DNA, mRNA, and tRNA
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.
What does not directly participate in translation ribosomes mrna trna DNA?
It's DNA
Is the nucleotide sequence in an mRNA codon an exact copy of the DNA triplet that coded for it?
No. It's the RNA nucleotides that code for the DNA. The tRNA then in turn codes for a specific protein. So, for example, if the DNA sequence is TAG, the tRNA is AUC. (Uracil replacing thyamine in RNA)
How is dna made into mRNA?
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.

What happeneds in synthesis?
First, the DNA polymerase makes a copy of the DNA. The nucleotides then bond together and form a complete mRNA strand. The mRNA strand travels out to the cytoplasm through the nucleus. The mRNA is then met by a ribosome and tRNA. Codons and amino acids are then created. After the tRNA detaches from the mRNA strand, the amino acids are connected by a polypeptide bond. This results in a protein. So basically... Protein synthesis is going from DNA to mRNA to tRNA to a protein.
What macromolecule is made up nucleic acids?
Both Dna and RNA are made of nucleotides. RNA comes in tRNA, mRNA and rRNA forms as as well.
When tRNA copies mRNA it is called what?
mRNA does not copy DNA, intead, mRNA is copied FROM DNR. The process is call translation.

Where is the process of making mRNA from DNA called?
DNA to mRNA is transcription, whereas mRNA to tRNA is translation. The latter part is when proteins are made from ribosomes and instructions carried over by mRNA from the DNA.
What is the form of RNA that is transcribed from DNA?
A. rRNA Type of RNA molecule transcribed from a DNA template B. codon Sequence of three nucleotides on a messenger RNA molecule C. tRNA RNA component of ribosomes D. anticodon Connects mRNA codon to an amino acid E.mRNA Sequence of three nucleotides on a transfer RNA molecule

What is a group of three nucleotides called?
This arrangement is called a codon.In DNA and RNA a group of three nucleotides in a row is called a codon. In tRNA a group of three nucleotides is called an anticodon.
Why is specific base pairing essential to the process of transcription and translation?
During transcription, an mRNA (also called a gene message or a messenger RNA) is produced using DNA as the template. The gene on the DNA has specific sequences that are transcribed and this process heavy relies on base pairing interactions between the DNA and RNA as wells as between DNA and the proteins that initiate transcription During translation, the mRNA or the genetic message is translated into proteins. This is done by structures called ribosomes. The ribosomes bind mRNA and recruit tRNA that contain the building blocks of proteins called amino acids. The tRNA molecules recognize groups of three nucleotides on the mRNA called codons and protein synthesis (the order in which the amino acids are assembled) is dependent on base pairing between the tRNA and mRNA For these reasons, specific base pairing is essential to transcription and translation
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.
What determines whether or not a specific tRNA can bind to an mRNA?
Messenger RNA (mRNA) is composed of long strings of nucleotides. These nucleotides are further arranged into groups of three, called codons. There are 64 possible combinations of codons, and they code for 20 amino acids in all (some amino acids are coded for by more than one codon.) Transfer RNA (tRNA) is composed of the same nucleotides as mRNA. One specific location on a tRNA molecule, known as the anticodon, is capable of linking to the codon on the mRNA. This is determined by the same rules that allow these bonds to form in other DNA/RNA. Uracil may link with Adenine, and Cytosine may link with Guanine. U and A form two hydrogen bonds, while C and G form three. Thus, a tRNA's anticodon (and, more specifically, the rules governing the bonds between nucleotides) is what determines whether it will bind to an mRNA codon, bringing with it the amino acid that the mRNA codon codes for.
