DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following holds the original coded information for making proteins?
A
rRNA
B
mRNA
C
tRNA
D
DNA
Explanation: 

Detailed explanation-1: -To manufacture protein molecules, a cell must first transfer information from DNA to mRNA through the process of transcription. Then, a process called translation uses this mRNA as a template for protein assembly.

Detailed explanation-2: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Detailed explanation-3: -Genes are small sections of DNA within the genome that code for proteins. They contain the instructions for our individual characteristics – like eye and hair colour.

Detailed explanation-4: -DNA (or deoxyribonucleic acid) is a long molecule that contains our unique genetic code. Like a recipe book, it holds the instructions for making all the proteins in our bodies.

Detailed explanation-5: -The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health.
