代写论文:DNA分离技术

脱氧核糖核酸是携带遗传指示的重要元素。这些嵌入式指令在确定所有已知活生物体和许多病毒的生长,发育,功能和繁殖方面起着重要作用。为了DNA提取和可视化细胞需要整理,需要打开细胞膜以暴露DNA以及细胞质。然后用盐溶液处理溶液以使蛋白质,RNA和脂质的组分聚集在一起。然后用溶液混合物进行离心。这是一个用于分离DNA不同元素的过程。观察到含有在DNA内发现的结块的细胞碎片。在细胞裂解步骤中使用来自去污剂,盐,试剂的DNA纯化步骤。为此,进行乙醇沉淀,苯酚 – 氯仿萃取或小柱萃取步骤。这个过程中的每一步都是根据研究的最终目标来确定的。

有特定的DNA分离技术。细胞蛋白和组蛋白通过加入蛋白酶与膜结合(Freeland,2011)。在分离DNA之后,将它们溶解在碱性黄油中。他们在TE鸡奸或清水中。这个实验的目的是确定鸟类DNA的性别鉴定。了解异性性行为是必不可少的。这是DNA的基本类比。异性性别是指性染色体不同的物种的性别。在人类中,男性物种有x和Y染色体,被认为是异性性行为。另一方面,对于女性来说,它将是XX染色体,并被称为同性恋性别。

Deoxyribonucleic acid is an important element that carries genetic instructions. These are embedded instruction that play an important role in the determination of the growth, development, functioning and reproduction of all known living organisms and many viruses. For the DNA extraction and visualization cells need to be collated, cell membranes need to be open to expose the DNA along with the cytoplasm. The solution is then treated with a salt solution to make the components of protein, RNA and lipid to be clumped together. Then centrifugation is done with the mixture of solution. This is a process that is used for the separation of the different elements of the DNA. It is observed to contain clumped cellular debris that is found inside the DNA. The DNA purification steps from the detergent, salt, regent are used during the cell lysis step. For this, the steps of ethanol precipitation, phenol-chloroform extracting or mini column extraction are done. Each of this process is determined based on the final objective of the research.

There are specific techniques for DNA isolation. The cellular proteins and histone proteins are bound to the membrane by the addition of a protease (Freeland, 2011). Subsequent to the isolation of the DNA, they are dissolved in alkaline butter. They are in the TE bugger or in the clear water. The purpose of this experimentation is to determine the bird DNA for sex identification. It is imperative to comprehend about the heterogametic sex. This is the basic analogy that exists for the DNA. The heterogametic sex refers to the gender of the species where the sex chromosomes are not the same. In human, male species have an x and Y chromosome and are considered to be heterogametic sex. On the other hand, for the female, it would be XX chromosome and would be referred as the homogametic sex.
