Translation

검증된 단계별 안내

Translation is the process in molecular biology where the sequence of a messenger RNA (mRNA) molecule is used to synthesize a specific protein.

This process occurs in the ribosome, which is the cellular machinery responsible for protein synthesis.

During translation, transfer RNA (tRNA) molecules bring amino acids to the ribosome, matching their anticodons to the codons on the mRNA sequence.

The ribosome facilitates the formation of peptide bonds between amino acids, creating a polypeptide chain that folds into a functional protein.

Translation is the second step of gene expression, following transcription, and is essential for converting genetic information into functional proteins.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Translation

Translation is the process by which ribosomes synthesize proteins from messenger RNA (mRNA) templates. During translation, the ribosome reads the sequence of codons in the mRNA, and transfer RNA (tRNA) molecules bring the corresponding amino acids to form a polypeptide chain. This process occurs in the cytoplasm and is essential for gene expression, as proteins are crucial for cellular structure and function.

Codons

Codons are sequences of three nucleotides in mRNA that specify a particular amino acid during protein synthesis. Each codon corresponds to one of the 20 amino acids or serves as a stop signal for translation. The genetic code, which is nearly universal among organisms, dictates how sequences of nucleotides are translated into the amino acid sequences of proteins.

Ribosomes

Ribosomes are complex molecular machines found within all living cells that facilitate the translation of mRNA into proteins. Composed of ribosomal RNA (rRNA) and proteins, ribosomes can be found free in the cytoplasm or attached to the endoplasmic reticulum. They play a critical role in decoding the mRNA sequence and catalyzing the formation of peptide bonds between amino acids, thus building proteins.
