Question

AUG GGC UCA Is this a strand of DNA or RNA, and how can you tell? a RNA because it has the nitrogen base, Uracil. b DNA because it has the nitrogen base, Adenine c RNA because it has inorganic phosphate groups d DNA because it has the sugar, Ribose

Answer 1

The sequence "AUG GGC UCA" is a strand of RNA. The key factor that indicates this is the presence of the nitrogen base uracil (U).

So, the answer is:

**a) RNA because it has the nitrogen base Uracil.**

In DNA, uracil is replaced by thymine (T), and RNA contains uracil instead of thymine. Additionally, RNA contains ribose sugar, while DNA contains deoxyribose sugar, but the presence of uracil is the most direct indication here.
