Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A type of RNA that associates with proteins to form ribosomes.;
A
Intron
B
RNA
C
Messenger RNA
D
Ribosomal RNA
Explanation: 

Detailed explanation-1: -Ribosomal RNA (rRNA) is the most common form of RNA found in cells – it makes up around 50% of the structure of the ribosomes. It is produced in the nucleus, before moving out into the cytoplasm to bind with proteins and form a ribosome. Transfer RNA (tRNA) is found in the cytoplasm and has a complex shape.

Detailed explanation-2: -Ribosomal RNA (rRNA) rRNAs combine with proteins and enzymes in the cytoplasm to form ribosomes, which act as the site of protein synthesis. These complex structures travel along the mRNA molecule during translation and facilitate the assembly of amino acids to form a polypeptide chain.

Detailed explanation-3: -Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells.
