Introduction
Tools for statistical analysis of DNA and protein sequences convey information e.g. about: - nucleotide and aminoacid content in sequence
- G+C content
- molecular weight, hydrophobicity or charge of proteins
- DNA melting temperature
- relative codon and aminoacid usage
Task no. 1 Using tool Cusp make up codon usage table for genes of ribosomal protein L1 from Escherichia coli and Streptomyces aureofaciens. Then try to compare: - realtive codon usage for aminoacid valine for these two microorganisms.
- What conclusion would you deduce from codon preference for valine according to systematic ranking of thses two microorganisms?
