Genomics — Quiz

Test your understanding of genomics with 5 practice questions.

Practice Questions

Question 1

Which of the following next-generation sequencing (NGS) platforms is most commonly used for whole-genome sequencing due to its high throughput and relatively low cost per base?

Question 2

During genome annotation, what is the primary computational challenge in accurately identifying the boundaries of protein-coding genes in eukaryotic genomes, particularly regarding alternative splicing?

Question 3

In comparative genomics, if two species exhibit a high degree of sequence similarity in a particular gene, but one species has an additional copy of that gene (a paralog) that has evolved a new function, what evolutionary phenomenon does this best illustrate?

Question 4

A researcher is investigating a complex disease and suspects that multiple genes contribute to its susceptibility. Which data interpretation approach would be most effective for identifying genetic variants across the entire genome that are statistically associated with the disease phenotype?

Question 5

When performing genome annotation, what is the significance of identifying 'CpG islands' in a mammalian genome?
