Question 1

Yeast Genome

Answer 1

1. Genome= 12 052 000bp, distributed on 16 chromosomes (compact genome).
2. Genes account for 72% of the sequence
   - 8% of duplicated material remains
   - ~6000 protein-coding genes
   - 40 genes for small nuclear RNAs
   - 275 genes for tRNA
3. 4777 protein-coding genes are of known function
4. 1/3 of yeast proteins have identifiable homologous in the human genome.

Question 2

Arabidopsis thaliana

Answer 2

1. Genome= 146 Mbp, distributed over five chromosomes.
2. Protein-coding genes: 5.4 exons, of an average of 276 bp, separated by 165 bp long introns
