Transcription occurs in the nucleus. Use DNA as a template to create an RNA molecule. The RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in the mRNA and creates a protein.

Where does the transcription process take place?

During transcription, a piece of DNA that codes for a specific gene is copied into messenger RNA (mRNA) in the nucleus of the cell. The mRNA then carries the genetic information from the DNA to the cytoplasm, where translation occurs.

Who does the transcription?

Transcription is carried out by enzymes called RNA polymerases, which join nucleotides together to form an RNA strand (using a DNA strand as a template).

Where does transcription take place in eukaryotic cells?

– In the eukaryotic cell, transcription takes place in the nucleus (nuclear membrane) and translation in the cytoplasm. – In eukaryotes, the chromatin containing the promoter sequence must be accessible to the transcription machinery.

Where is the translation done?

It is produced in the cytoplasm, where the ribosomes are found; in the eukaryotic cell it also occurs in the rough endoplasmic reticulum (RER), and the mitochondria have their own translation process. Ribosomes are made up of a small and a large subunit, which surround the RNA.

How is the translation process carried out?

Translation is the process of translating the sequence of a messenger RNA molecule (mRNA) into an amino acid sequence during protein synthesis. The genetic code describes the relationship between the sequence of base pairs in a gene and the corresponding sequence of amino acids that it codes for.

How does the translation process start?

The initiation of DNA translation occurs at the ribosome.

This organelle is assembled around a molecule of mRNA, where a tRNA will come. This last type of RNA must carry the amino acid methionine, encoded by the AUG codon, which is the signal to start the synthesis of the polypeptide chain.

What is transcription in eukaryotes?

Transcription is the first step in gene expression, in which a segment of DNA is transcribed into mRNA. In eukaryotic cells it takes place in the nucleus.

What is the process of transcription in eukaryotes?

Transcription is the process by which a copy of RNA is generated from the sequence of a gene. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes.

What is transcription in prokaryotes?

Transcription consists of the copy of 1 DNA chain to give an RNA chain, thanks to the complementarity of bases. The strand that is copied is known as the template strand or transcribed strand. This chain will obviously be complementary to the RNA.

How does transcription end in eukaryotes?

Transcription termination

RNA polymerase will continue transcribing until it receives the signal to stop. The process of ending transcription is known as termination, and it happens after the polymerase transcribes a DNA sequence called a terminator.

What is the difference between transcription in prokaryotes and transcription in eukaryotes?

– In prokaryotes there is no physical separation between transcription and translation, while in eukaryotes transcription takes place in the nucleus, where the DNA is, and translation in the cytoplasm where the ribosomes are.

What is text transcription?

What is the transcript about? Transcribing is copying something already written elsewhere, although when we speak of the transcription of documents we speak of the systematic representation of an oral form by means of written signs and we learn it as children.

Where does transcription occur in prokaryotes?

Prokaryotic Transcription

It begins when RNA polymerase couples to DNA at the promoter. The RNA Pol binds tightly to the promoter and causes the DNA double helix to open, initiating transcription.

What is the name of the codon that starts translation?

The translation start codon or start codon is an RNA sequence of three nucleotides (ie, a codon) that tells the cellular machinery where on the chain where translation of messenger RNA begins.

How is DNA transcription and translation carried out?

Transcription occurs in the nucleus. Use DNA as a template to create an RNA molecule. The RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in the mRNA and creates a protein.

What are the 4 stages of protein synthesis?

Main steps of protein synthesis

    Initiation. Elongation. Termination.

How does protein synthesis take place?

Protein synthesis occurs on ribosomes. The more protein a cell is making, the more ribosomes it will have, since each ribosome is one big protein-synthesising machine. Each ribosome has two binding sites, called P (peptidyl) and A (aminoacyl) sites.

What are the characteristics of text transcription?

The word transcription indicates the purpose of this type of writing: it is a document that serves to transcribe the content of the official letter as given in the original, in full and without any alteration. The entire transcribed fragment or paragraph must be between quotation marks and faithful to the original.

How many types of transcript are there?

There are different types of transcription, depending on the purpose to be given to the transcribed text:

    Verbatim transcript. … Natural transcription. … Phonetic transcription. … Music transcription.

What is transcribing a sentence?

tr. Write in one part what is written in another.

What is the difference between eukaryotic and prokaryotic cells?

The main difference between eukaryotic and prokaryotic cells is that eukaryotic cells have a nucleus. The nucleus is where cells store their DNA, which is their genetic material. The nucleus is surrounded by a membrane. Prokaryotic cells do not have a nucleus.

Where does transcription occur in prokaryotes and eukaryotes?

Transcription in eukaryotes. In the case of eukaryotes, the process takes place in the nucleus, and is similar to that of prokaryotes, but more complex. Different pRNAs transcribe different types of genes.

What is the difference between eukaryotic and prokaryotic genes?

Prokaryotic cells do not have a membrane-bound nucleus within which the genetic material is housed. Eukaryotic cells have a well-defined nucleus, surrounded by a double nuclear membrane, formed from the endoplasmic reticulum.

What is the result of DNA translation?

In the field of biology, it is the process by which a cell makes proteins using the genetic information carried by messenger RNA (mRNA). mRNA is made by copying DNA, and the information it carries tells the cell how to link amino acids together to form proteins.
