Question
___________ contains information required for the growth and function of an organism
- Nucleus
- DNA
- RNA
- Ribosomes
Hint:
The double stranded structure that contains thymine instead of uracil as nitrogenous base.
The correct answer is: DNA
- DNA or deoxyribose nucleic acid carries all the information for the growth and functioning of an organism.
- DNA is a double helical structure with two strands that are anti-parallel to each other.
- The DNA contains nucleotides made up of nitrogenous bases, sugars and phosphates.
- DNA has adenine, thymine, guanine and cytosine as nitrogenous bases.
- The information for the functioning of an individual depends upon the sequence of arrangement of the nucleic acids on the DNA strand.
