Question

Which of the given features is incorrect?

(a) TEs are present in few particular chromosomes

(b) TEs are present in all of the chromosomes

(c) Abundance of TEs varies

(d) TEs can comprise a large portion of the genomes of higher eukaryotes, both plants and animals

The question was posed to me during an interview for a job.

This interesting question is from Genome Anatomy in section Collecting & Storing Sequences in Laboratory of Bioinformatics

Answer 1

Correct option is (a) TEs are present in few particular chromosomes

For explanation I would say: TEs are present in all of the chromosomes, ranging from bacteria to humans, but their abundance varies. They can comprise a large portion of the genomes of higher eukaryotes, thus, only a small fraction of the genome of these organisms carries gene sequences.
