This diploma thesis presents a development of web application for variability detection in the DNA sequence called Amplicode 2018. DNA consists of four nucleotides adenine (A), cytosine (C), guanine (G) and thymine (T) which are interconnected into sequence. The phenotype level differences are related to genetic code at the genotype level. Sequences with different variations can determine particular attributes, for example height, hair colour, pigmentation of the iris, predispositions to specific diseases, etc.
Web application Amplicode 2018 enables detection of sequence variations within a gene of choice using different open source tools. The entire tool and parameter selection is carried out using the user-friendly website, that can be used by users with limited knowledge of Linux operating system, commands and switches of open source tools. The end result is consistently provided in the same format, regardless the various intermediate steps. It offers the ability to analyse the quality of the detection of variations with respect to different tools and helps user in further wet lab decisions.
