Bioinformatics 1 Exercise 1

Notes

Introduction (Exercise 1)

Cheat sheet (Exercise 1)

Part I – NCBI databases, BLAST (Insulin sequences)

1.1 Find difference between insulin sequences in pig and human. Documente and discuss points 1-9.

1.2 Show that sequence cosing for C-peptide is less conserved than sequences for the A-chain and the B-chain

Part 2 – NCBI databases, OMIM (Monogenetic disorders)

Find information on SICKLE CELL ANEMIA and KABUKI SYNDROM.

2.1 Which genes/proteins are involved?

2.2 On which chromosome (arm, cytogenetic band) genes are located?

2.3 What is the position and strand on the human reference genome assembly (GRCh38/hg38)?

2.4 Can these genes also be found in the mouse?

2.5 Are there common mutations i.e. non-synonymous single nucleotide polymorphism (SNPs) known?

2.6 What is the function of the encoded proteins?

2.7 Find recent publications
