Question

Messenger RNA is produced in
A)Nucleus
B)Golgi apparatus
C)Endoplasmic reticulum
D)Ribosomes

Answer 1

Hint: The genetic material of eukaryotic organisms is present in the nucleus. Its function is to serve and maintain the integrity of the cell by making easier the transcription and replication processes. It's the largest organelle talking about a tenth of the entire cell volume.

Complete answer:
-The messenger RNA is mainly synthesized in the nucleus using the nucleotide sequence of DNA as a template.
-A molecule in cells that transfer codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm i.e the ribosomes is the Messenger RNA (mRNA).
-The making of mRNA from DNA is called transcription and it takes place in the nucleus.
 Elliot Volkin and Lazarus Astrachan in 1956 were the first scientists to explain the molecules of mRNA.

Additional Information: In DNA, the information cannot be decoded directly into proteins as it is first transcribed, or copied, into mRNA and the process known as a transcription. with each sequence of three nitrogen-containing bases in the mRNA every molecule of mRNA encoding the information for one protein (more than one protein in bacteria), specifying the incorporation of a particular amino acid within the protein. Through the nuclear envelope into the cytoplasm, the mRNA molecules are transported, where they are translated by the rRNA of ribosomes.
Prokaryotic organisms that lack a distinct nucleus. The mRNAs with a terminal 5′-triphosphate group and a 3′-hydroxyl residue are found in the exact transcribed copy of the original DNA sequence.
-Eukaryotic organisms have a well defined nucleus. The molecules of mRNA are more elaborate. further esterification of the 5′-triphosphate residue is taken and forms a structure called a cap. long runs of adenosine residues (polyA) present at the 3′ ends of eukaryotic mRNAs that are not encoded in the DNA but after transcription are added enzymatically.
So, the correct answer is,” Nucleus”

Note: -Through a process known as transcription, mRNA's play a major role in protein synthesis. An RNA copy of a DNA sequence for making a given protein is made.
-In an RNA version of the gene, the mRNA leaves the cell nucleus and moves to the cytoplasm where the proteins are made.
