Unlike dna, rna
a. has deoxyribose as the sugar within its nucleotide components.
b. contains two strands wrapped in a helix.
c. contains nitrogenous bases.
d. pairs uracil with adenosine instead of thymine.

The answer is D. pairs uracil with adenosine instead of thymine. Through the process of elimination, both DNA and RNA contain nitrogenous bases. However, DNA contains sugar deoxyribose within its nucleotide components while RNA contains sugar ribose. Also, DNA has 2 strands wrapped in a helix while RNA has only 1 strand. Thus, the correct choice is D. because RNA pairs uracil with adenosine instead of thymine like DNA.

Answer is the mitochondria and the chloroplast
