Top 3 Types of Multi-Gene Families | Gene Concept

The following points highlight the top three types of multi-gene families. The types are: 1. Pseudo Genes 2. Selfish Genes 3. Split Gene - Exons and Introns. Multi-Gene Families: Type # 1. Pseudo Genes: Genes often exist which resemble other genes but their base sequence shows errors that make it impossible to contain biological infor­mation. These are pseudo genes which [...]

DNA Repair System (With Diagram) | Mutation

The following points highlight the five important types of DNA repair system. The types are: 1. Direct Repair 2. Excision Repair 3. Mismatch Repair 4. Double-Strand Break Repair 5. SOS Repair. Type # 1. Direct Repair: It involves the reversal of DNA damage. (i) Photo-Reactivation: Pyrimidine di­nners (induced by UV rays) can be monomerised again by DNA photolyases in presence [...]
