Answer: c. proteasome

Explanation:

Proteasomes are extremely important multi-catalytic proteases and are involved in various cellular functions. The proteasome is an essential component of eukaryotic cells and is responsible for the ATP-dependent proteolytic degradation of most cellular proteins. They are present in the nucleus and cytosol and can represent up to 1% of total cell proteins. Proteasomes generally degrade proteins to small peptides, most of which are rapidly hydrolyzed by cytoplasmic exopeptidases. It catalyzes the rapid degradation of many enzymes, regulatory proteins, and eliminates abnormal proteins resulting from mutation or damaged proteins. The inability of this cellular organelle can lead to neurodegenerative diseases, such as Parkinson´s disease.

<h2>Answer is option " 2 & 4"</h2>

Explanation:

  • Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:  
  • m+g/mg : Parental  
  • mg+/mg : Parental  
  • m+g+/mg : Recombinant  
  • mg/mg : Recombinant  
  • m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
  • Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"

Explain the difference between El Nino and La Nina.
MAVERICK [17]

Hey there!

El Nino typically involves waters with a warmer than usual surface temperature, a flatter thermocline (cooler water moves to the surface), and weaker trade winds. As for La Nina, think of it as the opposite of El Nino. There will be stronger trade winds, and cooler surface water temperatures.

Hope this helps!
