DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
mRNA is analogous to
A
the original blueprints
B
a copy of the blueprints
C
the finished house
D
the building site
Explanation: 

Detailed explanation-1: -Explain how mRNA works like a blueprint in constructing proteins. The master plan is the DNA molecule. The cell uses the molecule to prepare mRNA “blueprints.” The mRNA carries the instructions for protein synthesis from the nucleus to the ribosomes in the cytoplasm, where the proteins are built.

Detailed explanation-2: -Messenger RNA (mRNA) is the cell’s blueprint for building proteins. It is a single stranded RNA molecule that encodes genetic information from DNA to be translated into functional protein molecules.

Detailed explanation-3: -An analogy that teachers often use is to think of your DNA as a giant cookbook. In that case, the role of mRNA is to copy a recipe from the cookbook and then bring it to the part of the cell that uses it to build a protein.

Detailed explanation-4: -Definition. Transcription, as related to genomics, is the process of making an RNA copy of a gene’s DNA sequence. This copy, called messenger RNA (mRNA), carries the gene’s protein information encoded in DNA.
