Answer:
Protein: 3. This folded amino acid chain is genetically encoded and performs specific functions in the cell.
DNA: 1. This series of nucleotides encodes proteins.
Chromatin: 4. This substance is made up of fibers that are formed in the nucleus by supercoiling genetic material.
Histones: 2. These proteins regulate transcription and modifications of genetic material.
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.
<span>The nitrogen cycle could not exist without first nitrogen. The cycle is about this specific element which goes to show that if this element is not present then, there will not be any nitrogen cycle. Also, an important factor for the cycle is the presence of the bacteria and other microorganism which are needed for the fixation. </span>
