Difference Between 16s rRNA and 16s rDNA

Key Difference – 16srRNAvs 16s rDNA

核糖体的生物网站吗蛋白质合成in all living organisms. Ribosomes contain two components; small subunit and a large subunit.原核生物和真核生物differ from the composition of ribosome they contain. Each subunit is composed of ribosomal RNA and different proteins. These two subunits fit together and work as one during the protein synthesis. Prokaryotic ribosomes are the 70S and they are composed of 30S small subunit and 50S large subunit. Eukaryotic ribosomes are 80S and they are composed of 40S small subunit and 60S large subunit. In prokaryotes, ribosomal RNA of the small subunit of ribosomes is known as 16srRNA. This 16s rRNA is transcribed from the chromosomal DNA which is known as 16s rDNA. 16s rDNA is the gene which produces 16s rRNA by the transcription. Thekey differencebetween the 16s rRNA and 16s rDNA is that16s rRNA is the transcribed single-stranded ribosomal RNA which is a component of the small subunit of prokaryotes while 16s rDNA is the double-stranded chromosomal DNA or the gene that code for 16s rRNA.16S rRNA的基因是16S rDNA。

什么是16s rRNA？

rRNAis a component of ribosomes. 16s rRNA is the specific component of 30S small subunit of the prokaryotic ribosome that binds with Shine-Dalgarno sequence. This 16s rRNA sequence shows high variability among the bacterial species. Hence, it can be used for the bacterialphylogeny and taxonomy.

什么是16s rDNA？

原核生物有70次核糖体。核核糖体的小亚基是30年代。30S小亚基的核糖体RNA（rRNA）称为16S rRNA，基因16S rDNA编码它。因此，16S rDNA被称为16S rRNA基因。16S rDNA是染色体DNA。它是双链的，它是由编码和非编码区组成的基因。当转录16S rDNA基因时，它会产生16S rRNA序列。16S rDNA是原核生物中的通用DNA序列。然而，原核生物中16S rDNA的序列各不相同。它促进了16S rDNA序列在准确鉴定细菌物种以及发现新型细菌物种方面的使用。

16S rDNAplays an important role in bacterial phylogeny and taxonomy. Therefore, it is used as a reliable molecular marker in phylogenetic studies of prokaryotes since it is highly conserved between different species. 16s rDNA nucleotide sequence has nine hypervariable regions (V1-V9) that provide a good source for differentiation ofbacteria and archaea.

16S rDNA基因的测序已促进细菌重新分类为新物种或属。因此，该基因用于分子实验室中，用作鉴定微生物的最常见的管家标记。有几个原因使16srDNA成为鉴定微生物的最佳标记，例如在所有细菌中存在16srDNA，这是16S rDNA基因功能的不变性质，以及使其大小的16S rdna使它成为足以提供信息目的。

16S rRNA和16S rDNA之间的相似之处是什么？

• 两者都是nucleic acids.
• 两者都是made up ofnucleotides.
• 两者都是related to ribosomal RNA.

摘要 - 16srRNAvs 16s rDNA

16s rRNA is the ribosomal RNA component of the small subunit of ribosomes of prokaryotes. The gene 16s rDNA encodes this RNA sequence. 16s rRNA is single-stranded and 16s rDNA is double-stranded. This is the difference between 16s rRNA and 16s rDNA.
