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.
Which of the following statements concerning recombinant
DNA technology is false?
(a) Thus far, no illnesses in laboratory workers have been
traced to genetic recombinants.
(b) Production of large amounts of proteins such as insulin
and human growth hormone has been made possible us-
ing recombinant DNA technology.
(c) Recombinant DNA technology offers specific benefits
to the scientific, medical, and general populations.
(d) Mutant strains of bacteria produced by genetic re-
combination are often unable to survive in the natural
environment.
(e) Recombinant DNA technology provides a high degree
of risk to the health of the general populations.
