nonsense codon
解釋
無義密碼子-
Analysis of the sequence variation of cytochrome b gene indicated that there is no evidence of insertions or deletions, i. e., they are all of identical length of 1143 bp in all the sequences of cytochrome b gene. further, the sequences can be fully translated into amino acid using chicken mitochondrial codon without nonsense mutations or intervening stop codons. the 1143 bp cytochrome b alignment contained 416 variable sites, of which 306 were parsimony informative sites with the strongest variable in third codon positions and less variable in first and second codon positions
細胞色素b基因序列變異分析表明: 1 )雁形目鳥類細胞色素b基因全序列長度一致,無插入和缺失:對照雞線粒體密碼子系統全序列能全部翻譯成氨基酸序列,無無義突變,全序列內部無終止密碼子; 2 )序列比對后1143加,含416個核著酸變異位點, 306個簡約信息位點,其中處於密碼子第三位的變異最大,第一位和第二位堿基的變異相對較小。
