Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Since DNA can’t leave the nucleus, mRNA carries the message from the nucleus to the ____
A
ribosomes
B
mitochondria
C
chloroplast
D
lysosomes
Explanation: 

Detailed explanation-1: -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. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.

Detailed explanation-2: -The nucleus does contain nuclear pores, however, DNA cannot exit the nucleus. Messenger RNA (mRNA), on the other hand, can exit the nucleus and enter the cytosol, where it can bind to ribosomes and undergo translation; therefore, statement III is false.

Detailed explanation-3: -Export of mRNA from the nucleus to the cytoplasm takes place through a pore complex in the membrane of the nucleus. Export is believed to involve the attachment of an adapter protein to the mRNA.

Detailed explanation-4: -messenger RNA (mRNA), molecule in cells that carries codes from the DNA in the nucleus to the sites of protein synthesis in the cytoplasm (the ribosomes).

Detailed explanation-5: -This mRNA can undergo processing in the nucleus. And once this is complete, the mature mRNA can then exit the nucleus through the nuclear pores to enter the cytoplasm. In the cytoplasm, the mRNA can bind to a specialized organelle called the ribosome.
