What is transcription and translation?

The process by which DNA is copied to RNA is called transcription, and that by which RNA is used to produce proteins is called translation.

What happens during translation?

In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.

Where does the process of transcription start?

Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.

What happens at the end of transcription?

Termination is the ending of transcription, and occurs when RNA polymerase crosses a stop (termination) sequence in the gene. The mRNA strand is complete, and it detaches from DNA.

What is the process of transcription?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). … The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.

What is the purpose of transcription?

Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene’s DNA sequence.

What is the process of translation?

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

What are the 5 steps of transcription?

Transcription can be broken into five stages: pre-initiation, initiation, promoter clearance, elongation, and termination:Pre-Initiation. Atomic Imagery / Getty Images. … Initiation.

What are the 3 stages of transcription?

RNA Transcription Process: The RNA transcription process occurs in three stages: initiation, chain elongation, and termination. The first stage occurs when the RNA Polymerase-Promoter Complex binds to the promoter gene in the DNA.
