What is a repetitive element? what are the types of repetitive elements? what is their effect on the ease of determining/analyzing a genome sequence?

Solutions

Expert Solution

- Repetitive elements are the patterns of nucleic acids - DNA or RNA that occur in multiple copies throughout the genome.

- The types of repetitive elements include -

1. Tandem repeats

2. Satellite DNA

3. Interspersed repeats

4. Transposable elements

- Repetitive elements exhibit a high degree of polymorphism due to variation in number of their repeats. This hyprvariability makes repetitive elements excellent markers for mapping.
