Answer
A strand exchange protein is a type of protein that facilitates the exchange of strands between homologous DNA molecules during the process of homologous recombination.
Solution
a
Function: Strand exchange proteins play a crucial role in homologous recombination, a process essential for DNA repair, genetic diversity, and proper segregation of chromosomes during meiosis
b
Mechanism: These proteins bind to single-stranded DNA and promote the pairing with a homologous double-stranded DNA, facilitating the exchange of DNA strands
Key Concept
Strand exchange proteins are essential for homologous recombination.
Explanation
They bind to single-stranded DNA and promote the exchange of strands with homologous double-stranded DNA, aiding in DNA repair and genetic diversity.
