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.

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 that copy of the DNA message that can enter the cytoplasm?

mRNA (messenger RNA) is the RNA molecule that carries a copy of the DNA message from the nucleus to the cytoplasm. Once in the cytoplasm, mRNA is used as a template for protein synthesis during translation.

What is the direction of synthesis for RNA molecules, specifically in terms of nucleotide addition from the 5' to 3' end?

RNA molecules are synthesized in a direction where nucleotides are added from the 5' end to the 3' end.

What macromolecule is built during transcription?

During transcription, an RNA molecule is built using a DNA template. This RNA molecule is an intermediate step in the process of protein synthesis.

How does RNA polymerase use DNA?

RNA polymerase reads the DNA template and synthesizes a complementary RNA strand by linking together RNA nucleotides according to the base pairing rules. RNA polymerase moves along the DNA strand in the 3' to 5' direction, synthesizing the RNA transcript in the 5' to 3' direction.

During protein synthesis where does the cell get information?

The cell gets the information for protein synthesis from DNA in the nucleus. The DNA is transcribed into messenger RNA (mRNA), which carries the genetic code from the nucleus to the ribosomes in the cytoplasm where the actual protein synthesis takes place.

What is the process of post-transcriptional modification?

Post-transcriptional modification involves altering the primary transcript of RNA to produce a mature and functional mRNA molecule. This process includes steps such as splicing, 5' capping, and polyadenylation to create a stable mRNA transcript that can be efficiently translated into protein by the ribosome. These modifications can regulate gene expression and enhance mRNA stability and translation efficiency.

What is the biological term for RNA synthesis?

Transcription is the biological term for RNA synthesis.

Does transcription require RNA polymerase for the synthesis of RNA molecules?

Yes, transcription requires RNA polymerase for the synthesis of RNA molecules.

What is the directionality of RNA synthesis, and how is it related to the 5' to 3' orientation?

RNA synthesis occurs in a 5' to 3' direction, meaning that nucleotides are added to the growing RNA strand starting from the 5' end and moving towards the 3' end. This directionality is important for the proper assembly of RNA molecules and is essential for the functioning of the genetic code.

What is the directionality of RNA synthesis, and how is it related to the concept that RNA is synthesized from 5' to 3' end?

RNA synthesis occurs in a specific direction known as 5' to 3'. This means that RNA is synthesized starting from the 5' end and extending towards the 3' end. This directionality is important for the proper assembly of RNA molecules and is related to the concept that RNA is built in a specific order, similar to reading a book from the beginning to the end.
