+# Instructions
+
+Your task is determine the RNA complement of a given DNA sequence.
+
+Both DNA and RNA strands are a sequence of nucleotides.
+
+The four nucleotides found in DNA are adenine (**A**), cytosine (**C**), guanine (**G**) and thymine (**T**).
+
+The four nucleotides found in RNA are adenine (**A**), cytosine (**C**), guanine (**G**) and uracil (**U**).
+
+Given a DNA strand, its transcribed RNA strand is formed by replacing each nucleotide with its complement:
+
+- `G` -> `C`
+- `C` -> `G`
+- `T` -> `A`
+- `A` -> `U`

+If you want to look at how the inputs and outputs are structured, take a look at the examples in the test suite.

+# Introduction
+
+You work for a bioengineering company that specializes in developing therapeutic solutions.
+
+Your team has just been given a new project to develop a targeted therapy for a rare type of cancer.
+
+~~~~exercism/note
+It's all very complicated, but the basic idea is that sometimes people's bodies produce too much of a given protein.
+That can cause all sorts of havoc.
+
+But if you can create a very specific molecule (called a micro-RNA), it can prevent the protein from being produced.
+
+This technique is called [RNA Interference][rnai].

+# Instructions
+
+Determine if a triangle is equilateral, isosceles, or scalene.
+
+An _equilateral_ triangle has all three sides the same length.
+
+An _isosceles_ triangle has at least two sides the same length.
+(It is sometimes specified as having exactly two sides the same length, but for the purposes of this exercise we'll say at least two.)
+
+A _scalene_ triangle has all sides of different lengths.
+
+## Note
+
+For a shape to be a triangle at all, all sides have to be of length > 0, and the sum of the lengths of any two sides must be greater than or equal to the length of the third side.
+
+In equations:
+
+Let `a`, `b`, and `c` be sides of the triangle.
+Then all three of the following expressions must be true:
+
+```text
+a + b ≥ c
+b + c ≥ a
+a + c ≥ b
+```
+
+See [Triangle Inequality][triangle-inequality]
