9/24/2023 0 Comments Transcription translation steps![]() ![]() Translation, following transcription, is a step in protein synthesis. The enzymes involved in translation are ribozymes.ĭNA replication is a preparatory step to cell division (mitosis or meiosis). Conversely, the flow of genetic information in translation is from mRNA to protein via complementary base pairing with tRNA in terms of adenine-uracil (AU) and guanine-cytosine (GC) base pairing. The enzymes involved in the process are DNA polymerases. The flow of genetic information will be from DNA to DNA by complementary base pairing in terms of adenine-thymine (AT) and guanine-cytosine (GC) base pairing. TranslationĭNA replication is the process of producing an exact copy of a polynucleotide strand such as DNA. In the latter, the genetic code from the mRNA is read as a trinucleotide codon, i.e. In the central dogma of molecular biology, the genetic information is schematically shown to flow from DNA to DNA (by replication) and from DNA to mRNA ( transcription) to protein ( translation). protein folding or post-translation modifications).Įtymology: The term translation comes from the Latin trānslātiōn, meaning “a transferring”, equivalent to trānslāt(us) + -iōn. ![]() Eventually, translation stops, and the newly formed protein undergoes maturation (e.g. The stop codon in the transcript signifies that the termination phase is reached.The amino acids are joined in a chain by a peptide bond. This is followed by translation elongation wherein a specific order of amino acids is brought to the ribosomal site by the tRNAs according to the sequence of codons in the mRNA transcript.During initiation, the ribosome binds to the mRNA and then the tRNA attaches to the start codon of the transcript.The three general steps of translation are initiation, translation elongation, and translation termination. ![]() Translation is the process of translating (converting) the transcript (genetic information) from the mRNA into a specific sequence of amino acids in the growing chain of a polypeptide. ![]()
