Can proteins be made without DNA?

Answer by  Meredith92 (158)

DNA is the instructions for building proteins. Without DNA proteins cannot be produced. DNA has a set of codes that make amino acids. In certain sequences those codes then build a protein. Without DNA you would not be able to make the essential 20 amino acids, which in turn make the protein.

Yes. Proteins are mad up of amino acids as their building blocks. DNA is made up on nucleotides as its building blocks. DNA is a blueprint/set of instructions in living organisms, enabling them to build proteins. Simple proteins can also be made in a laboratory setting.

No. Proteins are synthesized by a machinery called ribosomes which reside in the cytosol. Ribosomes reads messenger RNA (mRNA) with aids of multiple transfer RNA (tRNA) and other ribozymes to translate the mRNA into protein. mRNAs are transcribed from DNA, and therefore, DNA (blueprint material) is essential to produce protein.
