A large variety of plants, animals, and microbes found on earth and they differ in size, shape, colour, habitat, and many other characteristics. So, studying each of them is impossible. Therefore, scientists have devised mechanisms to classify all living organisms on certain rules and principles that allow identification, nomenclature, and finally classification of an organism.
For example, based on presence of three pairs of legs and 2 pairs of wings, an organism is identified as an insect, it will be given a scientific name and then grouped with other similar organisms. Thus, various groups or taxon include organisms based on their similarity and differences.
Therefore, the biological classification helps in revealing the relationship between various organisms. It also helps in making study of organisms easy and organized.
NCERT questions are designed to test your understanding of the concepts and theories discussed in the chapter. Here are some tips to help you answer NCERT questions effectively:
Welcome to the NCERT Solutions for Class 12 Biology - Chapter . This page offers a step-by-step solution to the specific question from Excercise 1 , Question 9: Does our blood have proteases and nucleases?....
Comments
human blood have proteases like prothrombin which is an inactive form of thrombin which help in clotting of blood . But it did not contain any nucleases
No, blood cannot have active proteases and nucleases as it will lead to degeneration of blood proteins by proteases and nucleic acid present in WBCs of blood will be destroyed by nucleases and that will ultimately lead to death of WBCs. But blood can have inactive proteases like prothrombin which is activated during blood clotting.
Yes, there are some proteases and nucleases in Blood. Protease like thrombin is found in inactive form thrombinogen, plasmin in the form of plasminogen etc.DNase 1 and DNase1I3 are serum nucleases of human being. Kindly correct
