transcription:
"the first step in protein synthesis, a sequence of nucleotide bases becomes exposed in an unwound region of a DNA strand. That sequence acts as a template upon which a single strand of RNA - a transcript - is synthesized from free nucleotides."
The synthesis of an RNA molecule from the DNA template strand is called transcription.

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.
The function of transfer RNA molecules is to?
The tRNA helps to form amino acid in the cytoplasm during protein synthesis as a specific enzymes for activation and for attaching itself to corresponding tRNA. The tRNA has an anticodon complementry to the appropriate codon of the RNA.
Anti codons are part of the structure of?
An anticodon is a three nucleotide sequence found as part of Transfer RNA. The anticodon is the portion of the tRNA that binds to the relevant portion of the messenger RNA (mRNA). Overall, the anticodon assists in matching amino acid sequences to mRNA codon sequences during protein synthesis.
What is the second step of protein synthesis?
Initiation:In the cytoplasm, protein synthesis is actually initiated by the AUG codon on mRNA. The AUG codon signals both the interaction of the ribosome with m-RNA and also the tRNA with the anticodons (UAC). The tRNA which initiates the protein synthesis has N-formyl-methionine attached. The formyl group is really formic acid converted to an amide using the -NH2 group on methionine (left most graphic)The next step is for a second tRNA to approach the mRNA (codon - CCG). This is the code for proline. The anticodon of the proline tRNA which reads this is GGC. The final process is to start growing peptide chain by having amine of proline to bond to the carboxyl acid group of methinone (met) in order to elongate the peptide.
Where do you find a anticodon?
Codon is found on the messenger RNA(m RNA).During translation, the codons on the m RNA are read by the ribosome and amino acid corresponding to the codon is added. when ribosome encounters a stop codon (UAG,UGA and UAA) translation terminates.
What is the RNA transcript that has the single stranded RNA?
All RNA is single-stranded. Messenger RNA (mRNA), however, is a transcript of DNA.
Rna that copy of the DNA message that can enter the cytoplasm?
Transcription is the synthesis of RNA under the direction of DNA. The type of RNA used during transcription is the messenger RNA. The mRNA carries a genetic message from the DNA to the protein-synthesizing machinery of the cell. Then, translation is the actual synthesis of a polypeptide, which occurs under the direction of mRNA.
What is the process of post-transcriptional modification?
Post-transcriptional modification is a process in cell biology by which, in eukararyotic cells, primary transcript RNA is converted into mature RNA. A notable example is the conversion of precursor messenger RNA into mature messenger RNA (mRNA), which includes splicing and occurs prior to protein synthesis. This process is vital for the correct translation of the genomes of eukaryotes as the human primary RNA transcript that is produced as a result of transcription contains both exons, which are coding sections of the primary RNA transcript.
What two steps must occur in protein synthesis?
The two main steps in protein syntheis are transcriptionand translation. In transcription, the enzyme RNA Polymerase uses a DNA strand as a template to make a transcript of messenger RNA. This transcript is then translated into protein by the ribosome.
Where does the RNA polymerase moves down?
RNA polymerase catalyze the synthesis of RNA by copying the DNA. It occurs in the 5' to 3' direction(moves down).
Rna processing converts the RNA transcript into?
mRNA
During protein synthesis where does the cell get information?
Transcription starts at a promoter and stops after the polyadenylation sequence
What is the biological term for RNA synthesis?
Transcription is the biological term for RNA synthesis.
What enzyme is responsible for RNA synthesis?
RNA polymerase
What contains RNA and is involved in protein synthesis?
Ribosomes contain RNA and is involved in protein synthesis. Mitochondria and plastids also contain RNA.
What macromolecule is built during transcription?
mRNA (and other RNA) molecule is built during transcription of DNA. mRNA transcript undergoes for processing to become mature. They transported to cytoplasm for the protein synthesis.
What is the name of the part of protein synthesis that makes messenger RNA?
Transcription is the synthesis of messenger RNA from DNA in the nucleus.
