What happens during translation quizlet?

What happens during translation? During translation, a ribosome uses the sequence of codons in mRNA to assemble amino acids into a polypeptide chain. The correct amino acids are brought to the ribosome by tRNA.

What happens in translation simple?

Translation is the process that takes the information passed from DNA as messenger RNA and turns it into a series of amino acids bound together with peptide bonds. The ribosome moves along the mRNA, matching 3 base pairs at a time and adding the amino acids to the polypeptide chain.

What happens during translation and transcription?

Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.

What are the steps involved in the process of translation?

Translation of an mRNA molecule occurs in three stages: initiation, elongation, and termination.

What are the three steps in transcription?

Transcription takes place in three steps: initiation, elongation, and termination. The steps are illustrated in Figure 2. Figure 2. Transcription occurs in the three steps—initiation, elongation, and termination—all shown here.

Why is splicing important?

Splicing makes genes more “modular,” allowing new combinations of exons to be created during evolution. Furthermore, new exons can be inserted into old introns, creating new proteins without disrupting the function of the old gene. Our knowledge of RNA splicing is quite new.

What are introns purpose?

Introns, from this perspective, have a profound purpose. They serve as hot spots for recombination in the formation of new combinations of exons. In other words, they are in our genes because they have been used during evolution as a faster pathway to assemble new genes.

Are introns important?

Introns are crucial because the protein repertoire or variety is greatly enhanced by alternative splicing in which introns take partly important roles. Alternative splicing is a controlled molecular mechanism producing multiple variant proteins from a single gene in a eukaryotic cell.
