DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A scientist puts nucleotide chains of UUUUUU in a test tube under conditions allowing protein synthesis. Soon they are only amino acids chains of phenylalinine. What does the experiment indicate?
A
phenylalanine is composed of uracil
B
UUU codes for phenylalanine
C
protein synthesis malfunctions in test tubes
D
proteins contain one kind of amino acids
Explanation: 

Detailed explanation-1: -The amino acids join together in peptide bonds (bottom), and the tRNA molecules are released to pick up additional amino acid molecules. After the protein has been synthesized completely, it is removed from the ribosome for further processing and to perform its function.

Detailed explanation-2: -The process of converting the mRNA ‘message’ into a sequence of amino acids is known as translation. The mRNA is decoded during the process of translation in which the ribosomes in the cytoplasm or the endoplasmic reticulum synthesizes the proteins in the cell’s nucleus after the process of transcription of DNA to RNA.

Detailed explanation-3: -Ribonucleic acid (RNA) is the nucleic acid responsible for using the genetic information encoded in DNA to produce the thousands of proteins found in living organisms.
