Gene Detection in DNA Sequences
Bahurek, Tomáš ; Burgetová, Ivana (referee) ; Martínek, Tomáš (advisor)
This work is about gene detection in DNA sequencies. It explains how the information in DNA is stored, shows preview of various gene prediction methods, describes picked methods and results of testing those methods on real data (genome of bacteria E. Coli K12), compares efficiency of methods with various paramaters and efficiency between methods.

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.

Analysis of single-cell genomic data of Saccinobaculus sp.
Gajdošová, Petra ; Treitli, Sebastian Cristian (advisor) ; Kolísko, Martin (referee)
The progress of single-cell genomics and metagenomics techniques allows us to explore the uncultured organisms in greater depth. In this work, we focused on the genome assembly and genetic code of the oxymonad Sacinobaculus ambloaxostylus, which inhabits the hindgut of wood-eating cockroaches from the genus Cryptocercus. Using single cell picking and whole genome amplification we obtained sequencing data from three cells of S. ambloaxostylus. The obtained data was used to generate a single-cell genome assembly using SPAdes. The assembly was further binned and decontaminated to remove any potential bacterial or eukaryotic contaminants. After decontamination and re-assembly, we obtained a genome assembly with a total length of ∼417Mbp distributed to ∼185 thousand scaffolds. Despite its low completeness of 13.71%, we attempted to determine the genetic code used by S. ambloaxostylus. For this we manually modeled 33 genes from various metabolic pathways. Aligning these gene models with homologs from closely related oxymonads, we calculated the usage of stop codons as sense codons with focus on conserved positions. Our results suggest that the stop codons UAA and UAG act as sense codons and most probably they encode glutamine. Our 18S rRNA phylogeny was unable to answer the question if the ciliate...
