Ans.
There are twenty amino acids that take part in protein synthesis. These amino acids act as precursor for all protein molecules and are known as essential amino acids. Plants can synthesize all twenty amino acids from simple precursors, while animals can make only twelve amino acids. Animals obtain remaining eight amino acids by eating plants.
Thus, the correct answer is 'option) D.'
The mRNA generated below was produced in the <em><u>nucleus </u></em>of the cell.
Messenger RNA or mRNA is a type of RNA that is an essential component of protein synthesis or gene expression. It is synthesized using the template that is the nucleotide sequence of DNA.
- The synthesis of the mRNA s called transcription
- The nucleus is the location of the production of mRNA in eukaryotic cells from linear DNA strands.
- It requires nucleotide triphosphates as substrates
- catalyzed by the enzyme RNA polymerase II.
Thus, the process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
