Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a kit for nucleic acid extraction. Background technique [0002] Nucleic acid is a biological macromolecular compound synthesized by many nucleotides. It is one of the most basic substances of life. It is divided into deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). RNA can be divided into ribose according to different functions. Somatic RNA (rRNA), messenger RNA (m RNA) and transfer RNA (t RNA). Nucleic acid widely exists in all animal and plant cells, microorganisms, and nucleic acids in organisms are often combined with proteins to form nucleoproteins. Different nucleic acids have different chemical compositions and nucleotide arrangement sequences. DNA is mainly concentrated in the nucleus, mitochondria and chloroplasts, while RNA is mainly distributed in the cytoplasm. [0003] Nucleic acid extraction includes the following types: ① Total RNA extraction; ② miRNA extrac...
