Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.
how DNA Base Damage
Can Be Reversed?
DNA is the genetic element in all cell types of prokaryotic and eukaryotic. DNA is double stranded helical in structure made of nitrogenous base pairs and phosphate sugars. DNA is packed in chromosomes.
DNA has nitrogen bases as purine and pyrimidines. Purines are Adenine and cytosine. Pyrimidine bases are Thymine and Guanine. Any change in these bases are said to be base pair mutation. The base pairs mutation can be reversed by base excision repair system.
