What is last steps during transcription?

RNA polymerase reaches the end of a gene.


What steps happen lasts during transcription?

RNA polymerase reaches the end of a gene.


How does RNA polymerase know where to start transcribing a gene into mRNA?

The enzyme that synthesizes RNA (RNA polymerase) binds specific DNA sequencesthat typically lie before the gene being transcribed. When everything it needs to start synthesis is properly assembled (any cofactors, etc.), only then can it begin transcribing DNA into RNA.


How does Transcription take place?

who? the transcription enzyme RNA polymerase, the promoter DNA and the terminator DNAwhere? in the cell nucleusInitiation The promoter, located in the DNA at the beginning of the gene becomes the binding site for the RNA polymerase. Elongation the RNA polymerase copies and peels away the copied DNA, after copied, the DNA joins back with its matching DNA strand while the newly made RNA leave the polymerase Termination the RNA polymerase reaches a special sequence of bases in the DNA template that signals the end of the gene.

What happens at end of transcription?

The transcription process stops.mRNA detaches and moves to the ribosomesTranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.


What happens at the end of transcriptions?

What happens first during transcription?

RNA polymerase reaches the beginning of the gene


How does DNA become protein?

By how in the nucleus, enzymes copy a gene to a molecule of RNA and then, RNA leaves the nucleus and binds to a ribosome, where the cell uses the sequence of nucleotides in RNA to create a particular sequence of amino acids-a protein.


What steps happen first during during transcription?

At first during transcription, RNA polymerase binds the promoter region of a gene to be transcribed. The end product would be the synthesized mRNA.


Why is the RNA in the cytosol much smaller than the RNA in the nucleus?

In the nucleus, RNA is transcribed from the entire gene. The genes contain both introns and exons. Only the exons contain the coding information for the protein. After transcription these long RNAs (called hnRNA) are processed to remove the introns. After adding a poly A tail, and a cap on the 5' end, the now much smaller RNA is exported into the cytosol where it can be translated.


What best describes the product of transcription?

Transcription is the second part of the Central Dogma of biology: DNA to RNA to Protein. At the end of transcription, there is an RNA copy of the DNA segment that has been spliced so that it only contains the coding sequences for the gene. That is then exported for translation. This segment, the direct project of transcription is messenger RNA or mRNA.


What structures can be transcribed to make mRNA?

In protein synthesis, the process of a coping the gene in the form of mRNA is called transcription. When the mRNA reaches the end of the coding sequence, the final amino acid gets added and the protein is complete.
