BIOMOLECULES AND ENZYMES

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.

Detailed explanation-2: -First, enzymes read the information in a DNA molecule and transcribe it into an intermediary molecule called messenger ribonucleic acid, or mRNA. Next, the information contained in the mRNA molecule is translated into the “language” of amino acids, which are the building blocks of proteins.

Detailed explanation-3: -Answer and Explanation: The correct option is a: nucleus, cytoplasm. DNA comprises information necessary for the synthesis of protein and is located within the cell’s nucleus.

Detailed explanation-4: -Proteins are the key working molecules and building blocks in all cells. They are produced in a similar two-step process in all organisms called protein synthesis – DNA is first transcribed into RNA, then RNA is translated into protein.

Detailed explanation-5: -Messenger RNA (mRNA) carries the instructions for making proteins. Like DNA, proteins are polymers: long chains assembled from prefab molecular units, which, in the case of proteins, are amino acids. A large molecular machine* called the ribosome translates the mRNA code and assembles the proteins.
