Insertional inactivation explain.

Posted by Shubham Mehra 7 years, 4 months ago

CBSE > Class 12 > Biology

1 answers

Brahmjot Kaur 7 years, 4 months ago

The selection of recombinants due to inactivation of antibiotic gene is a cumbersome procedure, because it requires simultaneous plaring on two plates having different antibiotics. Therefore, the alternative selectable markers have been developed, which differentiate recombinants from non-recombinants. It is based on their ability to produce colour in the presence of chromogenic substrate. In this process, a recombinant DNA is inserted within the coding sequence of an enzyme, beta-galactosidase. This results into inactivation of the enzyme, which os referred to as insertional inactivation. Therefore, the bacterial colonies having inserted plasmid, shows no colouration (recombinant colonies) while, those without plasmid will show blue colour. Here beta-galactosidase works as a reporter enzyme (produced by reporter gene) whose inactivity helps to identify transformed and non-transformed bacterial colonies.

These are two very different examples. They are not related in any way. Camels have humps for food storage and have their own adaptations whereas birds are larger so they have larger fat content which keeps them warmer.

1 answers

Yogita Ingle 7 years, 4 months ago

HIV is not transmitted via sweat.
AIDS is caused by the human immunodeficiency virus (HIV). By killing or damaging cells of the body's immune system, HIV progressively destroys the body's ability to fight infections and certain cancers. People diagnosed with AIDS may get life-threatening diseases called opportunistic infections, which are caused by microbes such as viruses or bacteria that usually do not make healthy people sick.
