Answer:
When it is compared to the human genome, the Drosophila melanogaster genome contains a higher proportion of exons (20%) and a minor proportion of introns (16.6%).
Explanation:
The Drosophila melanogaster genome contains 24 million bases (Mb) encoded by exons + 20 Mb introns + 76 Mb intergenic sequences = 120 Mb >>
- Exon sequences= (24 x 100)/120: 20 %
- Intron sequences= (20 x 100)/120: 16.6 %
- Intergenic sequences= (76 x 100)/120: 63.3 %
On the other hand, the completion of the human genome sequencing showed that only 1.1% encodes proteins (i.e., they are exons), 24% are introns, and 75% are intergenic sequences. Moreover, it is also important to highlight that the D. melanogaster genome contains about 13,000 protein-coding genes, while the human genome contains nearly 22,000-30,000 protein-coding genes.
