Observational experiments on Bartlett's microsomes in human cells
M.L. Barr et al. were the first to find a darkly stained vesicle in the interphase nucleus of nerve cells in female cats, but not in male cats. Since this vesic

Deletion localization-gene fine structure analysis
Deletion localization is a gene localization method in which a strain at the mutation position to be tested is recombined separately with a series of mutant str
Extraction of mitochondrial DNA from plant cells
In eukaryotes, in addition to the nuclear genome, there are cytoplasmic genomes, i.e., the mitochondrial genome and, in green plants, the chloroplast genome. Bo
Concurrent transduction and gene localization--a three-dot hybridization experiment
The distance between two genes can be measured by the number of recombinants in the progeny after two- and three-point crosses. The closer the distance between
Gene Complementation Experiment
Genes are the smallest functional units of biological genetic material, and genes are separable. To determine the boundaries of a gene, it is not possible to re
Isolation and purification of chloroplast DNA from plant cells
Chloroplasts are unique organelles in plant cells and contain DNA. chloroplast DNA is in the form of a ring, and the chloroplast DNA (cpDNA) of higher plants va
Bacterial splicing and gene localization-disrupted hybridization
It is a method of range localization by physically interrupting the binding action of bacteria.
Non-isotopic labeling of DNA probes
DNA probes are divided into two categories: isotope-labeled probes and non-isotope-labeled probes. Isotope-labeled probes usually have high radioactivity and hi
Restriction endonuclease profiling of λ phage DNA
Lambda phage is a commonly used biological material in molecular genetics research, and the enzymatically fragmented segments of its DNA are often used as stand
