The process of translation involves three main types of RNA, including mRNA, tRNA, and rRNA, working together to decode information from DNA and build proteins in the ribosomes.
During the process of translation, mRNA decodes information from the original DNA master plan to build proteins in the ribosomes. This process involves three key types of RNA: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). The mRNA carries the genetic information copied from DNA in the form of a series of three-base code words, each of which specifies a particular amino acid.
The tRNA molecules act as adapter molecules, each able to carry a particular amino acid and recognise the appropriate codon in the mRNA. Through a series of steps, the tRNA molecules bind onto the mRNA and add their amino acid to the growing chain of amino acids that ultimately forms a functional protein.
Last but not least, the rRNA molecules come together with particular proteins to form a functional ribosome that facilitates the assembly of the amino acids into the new protein.

A part of the cell theory is cells come from pre-existing cells. The correct option is A.
The cell theory is the conclusion of many scientists. There are three postulates of the cell theory. They are: all organisms are made up of cells. New cells are made up of old cells, and the cell is the basic structural and functional unit of life.
The cell is the smallest and basic unit of life. All functions of the body are performed by cells. It contains a cell organelle that has different functions and structures.
A nucleus is present in the cell and microscopic organs must have a single cell, they are not a part of cell theory, this is more related to the organism, not cells.
Thus, the correct option is A. cells come from pre-existing cells.
