重组和非重组之间的差异

Key Difference – Recombinant vs Nonrecombinant

脱氧核糖核酸is the genetic material of almost all organisms. It is composed of核苷酸安排长链。有自然机制，enzymeswhich are able to change the nucleotide sequences and structures of DNA. Hence, DNA are frequently subjected to changes. Genetic recombination, which occurs duringsexual reproduction，它混合了两种类型的genomes。Genetic engineering is an advanced technology in molecular biology which artificially changes the genomes of organisms with foreign DNA. The words recombinant and nonrecombinant are used in molecular biology to describe DNA. Recombinant DNA refers to a piece of DNA which combines with another foreign DNA to form a new DNA molecule. Nonrecombinant DNA refers to the parental DNA or original DNA which does not contain any foreign DNA. The key difference between recombinant and nonrecombinant is that重组是指结合两种或多种类型的DNA（自己的DNA和外源DNA）的条件whilenonrecombinant refers to the condition of having only inherent DNA.

什么是重组？

The word recombinant refers to the DNA which is formed by combining DNA from multiple sources. It is a result of genetic recombination. Two different DNA are combined with each other to create a new DNA molecule which is not found in the original genome. It is known as recombinant DNA or chimeric DNA. Foreign DNA can be easily inserted into another organism genome to create a recombinant DNA molecule. The creation of recombinant DNA is done bygenetic engineering和重组DNA技术。重组脱氧核糖核酸is formed in laboratories by bringing together genetic material from different sources.

在分子生物学中，所需的基因与细菌重组质粒和expressed in bacteria. This process is known as molecular cloning. Using this technology, beneficial industrial products are produced in large scale. The proteins which result from the expression of recombinant DNA are known as recombinant proteins. Recombinant DNA has immense use in biotechnology, medicine, research, industry, food production, human and veterinary medicine, agriculture and bioengineering.

什么是非重组者？

非重组是指未显示任何遗传重组的状态。非重组DNA与亲本DNA相似。后代表演相似allelesarrangement as in the original parental DNA. As shown in figure 2, if there is no crossing over between chromosomes during the independent assortment, nonrecombinant DNA will be the result. If crossing over occurs, it results in recombinant DNA. The possibility ofchromatidexchange is some kind of genetic recombination. It results in DNA which are different from the original DNA. Nonrecombinant DNA is genetically same with the parental type.

重组和非重组剂有什么区别？

重组与非重组
重组脱氧核糖核酸is a piece of DNA that has been created by the combination of at least two strands.	Nonrecombinant is DNA which has not been subjected to genetic recombination.
Inserts
There is an insertion of foreign DNA into recombinant DNA.	没有外来DNA插入非重组DNA中。
Similarity to Parental DNA
重组脱氧核糖核酸is different from parental DNA.	Nonrecombinant DNA is the same as parental DNA.
Genetic Variation
重组DNA显示遗传变异。	Nonrecombinant DNA does not show genetic variation.

概括– Recombinant vs Nonrecombinant

The terms recombinant and nonrecombinant describes whether genetic recombination has occurred or not in DNA sequences. When DNA from multiple sources are combined, and a new DNA is formed, it is known as recombinant DNA. Genetic recombination is not possible all the time. When it genetic recombination doesn’t take place, it produces nonrecombinant DNA. Nonrecombinant DNA shows a similar genetic makeup to the parental DNA. This is the difference between recombinant and nonrecombinant DNA.
