Gene mapping in domestic animals

In comparison to many other fields of ultrastructural research in Cell Biology, the successful exploration of genes and gene activity with the electron microscope in higher organisms is a late conquest. Nucleic acid molecules of Prokaryotes could be successfully visualized already since the early sixties, thanks to the Kleinschmidt spreading technique - and much basic information was obtained concerning the shape, length, molecular weight of viral, mitochondrial and chloroplast nucleic acid. Later, additonal methods revealed denaturation profiles, distinction between single and double strandedness and the use of heteroduplexes-led to gene mapping of relatively simple systems carried out in close connection with other methods of molecular genetics.

The City

The article discusses main issues of organizing activities for the treatment of stray and street animals in the city of Novosibirsk. The important role of successful solving the problem of stray animals in ensuring environmental comfort and safety of the urban population is noted. Definitions of the concepts “stray animals” and “street animals” are given, the differences between them are emphasized. The main regulatory and legal documents governing the handling of stray and street animals are listed. The ways in which domestic animals get into a stray state are described briefly. The results of the collection and analysis of information on the activities of shelters for stray animals in Novosibirsk are described. The information on the quantitative indicators of the shelters are given. Conclusions on how to solve the problem of stray animals, relying on the latest regulations are drawn.
