The order that the nucleotides are arranged in form different "codes" to create traits. RNA in humans is used for transporting, and making the amino acid proteins. The order of amino acid proteins also changes the polypeptide formed, and changes more traits, and characteristics. Basically, it's like reading a book. Each book is made up of the same 26 letters, but their all arranged in different orders. You can find the some of the same words in another book, but no two books are exactly alike. All the letters and words are arranged in different ways, even though other books have the same letters and words.

<u>Answer</u>:- <em>Option 3 </em>(desert), <em>Option 4</em> (tundra) and <em>Option 5</em> (grassland).
<u>Explanation</u>:- 
The amount of rainfall varies in different biomes:-
1. Tropical rain forests - The annual rainfall in these forests falls in the range of <em>125 to 660 cm</em> which varies according to the seasons. 
2. Temperate rain forest - The annual rainfall in these forests can range from <em>200 cm to 350 cm</em> depending on the region where they are found. The annual rainfall is higher in warmer regions .
3. Desert - As the name suggests, the desert areas do not get enough rainfall. The annual rainfall in a desert is less than <em>25 cm</em>.
4. Tundra - It is a biome which is found in relatively cooler climates and the amount of rainfall is very less these regions. The annual rainfall in tundra biomes is less than <em>20 cm</em>.
5. Grassland - in these biomes, the rainfall is higher than the tundra and desert but is not as high as the rain forests and thus, grass is the dominant vegetation. The annual rainfall ranges from <em>60-90 cm</em>.
