10 Questions
What is the main function of insertion sequences?
Causing mutations by disrupting genes or regulatory regions
How do insertion sequences move within the genome?
By encoding a transposase enzyme
What is a key difference between transposons and insertion sequences?
Transposons can carry genes that provide additional functions
Which mechanism is unique to transposons, but not to insertion sequences?
'Copy-and-paste' mechanism
What is the primary limitation of insertion sequences in terms of mobility?
Limited to movement within the same genome
Which of the following is a characteristic of transposons?
They are typically larger in size and contain additional genes
What is the mechanism by which insertion sequences (IS) move within the genome?
Cut-and-paste mechanism
Which mobile genetic element can cause the phenomenon of hybrid dysgenesis in fruit flies?
Transposons
What role do transposons play in genome evolution and genetic diversity?
They play important roles in genome evolution and genetic diversity
What is a defining characteristic of insertion sequences (IS)?
They are the simplest form of transposable elements
