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.

Many archeologists and anthropologists disagree with dr. thorne's view.  thorne strongly believes that what many calls "homo erectus"  was in fact  homo sapiens,  and that they migrated out of africa almost 2 million years ago and dispersed throughout europe and asia. that's way different  from what scientists have always believed about the evolution of the species.
