  2. Sacharomyces cerevisiae

  3. Bacillus subtills

  4. Pseudomonas putida
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pseudomonas putida is a bacterium that has been developed through biotechnology for applications in the alcohol industry. It can be used for various biotransformations and has applications in industrial fermentation processes. The other options are incorrect: E. coli (typo in option), S. cerevisiae is yeast not bacteria, and B. subtilis is not specifically associated with alcohol industry biotechnology.

Progenitors formed in bone marrow but differentiating elsewhere are

  1. Pre-NK cells

  2. Pre-erythroblasts

  3. Pre-T cells

  4. Myeloblasts

C Correct answer
Explanation

Pre T cells are progenitors of T- lymphocytes which are produced from the bone marrow. Pre- T cells undergo differentiation and maturation in the thymus to form matured T- cells. T-cells can be distinguished from other lymphocytes by the presence of a T-cell receptor on the cell surface.  Hence, Progenitors formed in bone marrow but differentiating elsewhere are Pre-T cells.

So, the correct answer is 'Pre-T cells'.
