Detailed explanation-1: -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-2: -Specifically, messenger RNA (mRNA) carries the protein blueprint from a cell’s DNA to its ribosomes, which are the “machines” that drive protein synthesis. Transfer RNA (tRNA) then carries the appropriate amino acids into the ribosome for inclusion in the new protein.

Detailed explanation-3: -Each mRNA carries instructions to make a specific protein. These instructions are like a “blueprint.” mRNA delivers these instructions, and cells put the protein together.

Detailed explanation-4: -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-5: -During translation, ribosomal subunits assemble together like a sandwich on the strand of mRNA, where they proceed to attract tRNA molecules tethered to amino acids (circles). A long chain of amino acids emerges as the ribosome decodes the mRNA sequence into a polypeptide, or a new protein.
