Why is tRNA an interpreter?

The amino acids themselves cannot recognize the codons arranged in sequence along messenger RNA. It is up to the cell’s molecular interpreters, tRNA molecules, to match amino acids to the appropriate codons to form the new polypeptide.

What is the interpreter of translation biology?

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.

What is RNA and what is its role in translation?

RNA carries genetic information that is translated by ribosomes into various proteins necessary for cellular processes. mRNA, rRNA, and tRNA are the three main types of RNA involved in protein synthesis. RNA also serves as the primary genetic material for viruses.

What is RNA best described as?

Ribonucleic acid (RNA) is a molecule similar to DNA. Unlike DNA, RNA is single-stranded. An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups.

What is the purpose of transfer RNA?

Transfer RNA is that key link between transcribing RNA and translating that RNA into protein. The transfer RNA matches up via the anticodon to the specific codons in the messenger RNA, and that transfer RNA carries the amino acid that that codon encodes for.

What is RNA 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 is RNA in simple terms?

Short for ribonucleic acid. The nucleic acid that is used in key metabolic processes for all steps of protein synthesis in all living cells and carries the genetic information of many viruses. Unlike double-stranded DNA, RNA consists of a single strand of nucleotides, and it occurs in a variety of lengths and shapes.

What is the role of RNA?

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins. Specifically, messenger RNA (mRNA) carries the protein blueprint from a cell’s DNA to its ribosomes, which are the “machines” that drive protein synthesis. …
