Web Application for Bioinformatics Education - Genetic Code
Kilián, Martin ; Martínek, Tomáš (referee) ; Burgetová, Ivana (advisor)
This thesis briefly describes basic informations in moleculary biology. Thesis deals with a transfer of information from DNA into RNA through uprotein, are also briefly described the methods and algorithms dealing with the detection of genome. The larger part deals with the recognition cue coded signals and determination of sequences and their subsequent transcription and translation, which demonstration program was needed to create. The final result is s web application as the education system.

Methods for gene prediction in prokaryotic genomes
Nykrýnová, Markéta ; Sedlář, Karel (referee) ; Maděránková, Denisa (advisor)
This bachelor thesis deals with methods of gene prediction in prokaryotic genomes. First part of the thesis introduces prokaryotic cell, its genome, expression of genetic information and methods for gene prediction. Following part describes three software products for gene prediction. Chosen software was tested against specific genome and next chapter presents obtained results. The last part describes program called Gene_finder and its results.

Interactions among free-living prokaryotes and protists in microbial communities
Jirouchová, Kateřina ; Pánek, Tomáš (advisor) ; Fiala, Ivan (referee)
Protists and prokaryotes live in the natural environment in complex microbial communities whose members interact with each other. These communities consist of a few to many species that interact with each other in many ways such as predation/prey, ecto/endosymbiosis, parasitism, modulation of development or behaviour and harmful algicidal/bactericidal interactions, resulting in a complex network of interactions that influence structure of the microbial community as well as metabolism and behaviour of present species. This bachelor thesis is an overview of the interactions between free-living protists and prokaryotes within microbial communities, excluding well-studied interactions such as predation, parasitism, and ecto/endosymbiosis, while focusing on the diversity of lesser- known interactions, highlighting their importance and future research opportunities.

Ecological aspects of sexual reproduction
Toman, Jan ; Flegr, Jaroslav (advisor) ; Markoš, Anton (referee)
Sexual reproduction is one of the most interesting biological phenomena. No theory has ever entirely explained its wide occurrence among Eukaryotic clades despite its clear disadvantages (e.g. twofold price of sex). Theories can be divided into three groups according to the approach to solve this problem - molecular, genetic and ecological (environmental). Environmental theories are slightly preferred in the last decades and the opinion that the key to the sex enigma lies among them is widely accepted. Most of the environmental theories do not counter each other and there is possibility either to integrate them in several ways or presume that several of these theories might act simultaneously. According to theories, abiotically stable environments without biotic interactions (homogenous) should be suitable for and select for asexual species, whereas environments abiotically variable and rich in biotic interactions (heterogenous) should be suitable for and select for sexual species. The anagenetic phenomenon of punctuated equilibria and some of its explanations, e.g. P. R. Sheldon's Plus ça change hypothesis or J. Flegr's Frozen plasticity theory, also supports this division. There is a vast amount of empirical data supporting this division in ecological studies. Clearly homogenous environments...
