Three sequences, UAG, UGA, and UAA, known as stop codons, [note 1] do not code for an amino acid but instead signal the release of the nascent polypeptide from the ribosome. [7] In the standard code, the sequence AUG—read as methionine—can serve as a start codon and, along with sequences such as an initiation factor, initiates translation.

However, there are more than 31 tRNA anticodons possible for the translation of all 64 mRNA codons. For example, serine has a fourfold degenerate site at the 3rd position (UCU, UCC, UCA, UCG), which can be translated by AGI (for UCU, UCC and UCA) and AGC on tRNA (for UCG) but also by AGG and AGU.

2024年12月13日 · Translate the following mRNA sequence into the correct amino acid sequence. AUG-GAA-UCC-UAG. Use the table below to put the amino acids in order for your answer.

2024年4月12日 · For the DNA sequence AAAGAGCCT coding for an amino acid sequence, we must first convert it to the complementary RNA sequence UUUCUCGGA and then translate it into amino acids according to the genetic code. However, the exact amino acid sequence is not provided here as the answer is meant to reference Figure 2 which is not present.

Remind students of the different purposes of the mRNA and tRNA. It is the messenger RNA codon that carries the message specifying a certain amino acid; it is the transfer RNA that transfers that amino acid to the growing protein chain.

-AGC -UAG -AUG -UAG, The codon table identifies the amino acid sequence that can be translated from a human mRNA sequence. This chart can also be used to identify amino acid sequences for other organisms.

遗传密码又称密码子、遗传密码子、三联体密码，是指信使RNA (mRNA）分子上沿5'端到3'端方向，由起始密码子AUG开始，每三个核苷酸组成的三联体。 它决定肽链上每一个氨基酸和各氨基酸的合成顺序，以及蛋白质合成的起始、延伸和终止。 首个密码子是由美国科学家尼伦伯格于1961年完成。 尼伦伯格在无细胞系统环境下，将一条只由尿嘧啶组成的RNA体外翻译成一条只有苯丙氨酸（Phe）组成的多肽，由此破译了首个密码子（UUU -> Phe），随后科学家科拉纳破译了其 …
