Question

Which of the following is untrue?

(a) Eukaryotic nuclear genomes are much larger than prokaryotic ones

(b) They tend to have a very high gene density

(c) Eukaryotic nuclear genomes’ sizes range from 10 Mbp to 670 Gbp (1 Gbp = 109 bp)

(d) They tend to have a very high gene density

I got this question in an interview for job.

My doubt stems from Gene Prediction in Eukaryotes topic in portion Gene and Promoter Prediction of Bioinformatics

Answer 1

The correct answer is (b) They tend to have a very high gene density

To elaborate: In humans, for instance, only 3% of the genome codes for genes, with about 1 gene per 100 kbp on average. The space between genes is often very large and rich in repetitive sequences and transposable elements.
