Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following takes the genetic code from the nucleus to the ribosome?
A
DNA
B
deoxyribose
C
tRNA
D
mRNA
Explanation: 

Detailed explanation-1: -Complete step by step answer: The RNA which carries the genetic message from the nucleus to the ribosome is mRNA.

Detailed explanation-2: -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-3: -Definition. A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.

Detailed explanation-4: -Transport of proteins and RNA between the nucleus and cytoplasm is accomplished by soluble transport factors that bind their cargoes and carry them through numerous pores embedded in the nuclear envelope.
