正向和反向引物之间的差异|比较类似术语之间的差异

Key Difference – Forwardvs Reverse Primer

聚合酶链反应（PCR）is a DNA amplification method that is used in Molecular Biological applications. It is a commonly used technique that makes millions to billions of copies of a particularly interestedDNA序列。它是一个in vitro在实验室中执行的方法。PCR技术完全取决于商业生产DNA聚合酶称为TAQ聚合酶。而且它还需要其他几个组件和适当的温度维持。一个重要的组件是底漆。引物是专门为目标DNA序列设计的短DNA序列。他们通常大约20岁nucleotidesin length. Taq polymerase catalyzes the adding of nucleotides into preexisting nucleotide sequence. Hence, primers are served as starting points of the synthesis of new strands. Taq polymerase works only in 5’ to 3’ direction hence the DNA synthesis occurs in the same 5’ to 3’ direction. Since DNA is double stranded, two types of primers are needed in PCR. They are known as forward primer and reverse primer. Forward and reverse primers are termed based on the direction of the elongation of the primer in DNA when DNA synthesis occurs.Forward primer anneals with the反义DNA链并启动 +ve链的合成基因into 5’ to 3’ direction. Reverse primer anneals with the感官链并启动互补链的合成coding strand;这是 - 将基因的链纳入5 noto 3'方向。这是关键区别在正向和反向引物之间。

什么是前向底漆?

Forward orientation is the synthesis of the coding strand or the sense strand of a gene. Taq polymerase catalyzes the synthesis of a new strand in 5’ to 3’ direction. The synthesis of coding strand occurs when the primer anneals with the noncoding or the antisense strand and elongates in 5’ to 3’ direction.

图01：正向和反向引物

The primer that anneals with the antisense strand or the noncoding strand or the template strand is known as forward primer since forward primer acts as a starting point to the synthesis of coding or the positive strand of the gene. Forward primer has a short nucleotide sequence that is complementary to the 3’ flanking end of the antisense strand. It hybridizes with the antisense strand and facilitates the Taq polymerase to add nucleotides that are complementary to the template strand.

什么是反向底漆?

反向引物是用感官链或编码链的3'末端退火的短DNA序列。反向引物是合成编码序列或非编码序列的互补链的起点。反向引物的设计与编码链的3'端互补。因此，它以编码链的3'端退火，并允许TAQ聚合酶合成反义链或模板链。由于其方向是以相反的方式进行的，因此该引物被标记为反向引物。

Both reverse and forward primers are important for the production of millions to billions of copies of particular regions of DNA that are targeted or interested.

Summary – Forwardvs Reverse Primer

PCR技术涉及两种类型的引物。它们是向前的，反向底漆。基于新DNA链合成中底漆的伸长，这些底漆被标记或命名。TAQ聚合酶合成5'至3'方向的新DNA。因此，底漆被设计为对双链的3'端的互补。向前的底漆在5至3'方向上拉长，与反义或模板或非编码序列的3'末端杂交。它是合成编码序列的起点。反向底漆在5至3'方向上伸长，与编码的3'末端或非安装板或感官链杂交。它是合成非编码序列的起点。这是正向引物和反向引物之间的区别。
