Health- “But you made a simple mistake! mRNA is part of a macromolecule, not one itself!”
I don’t know what you are referring to- what part of what macromolecule is mRNA? Or in other words, what are the other parts of the macromolecule of which mRNA is allegedly only a part?
Just change the word macromolecule to “very large molecule” and see if this statement still makes sense.
Let’s get back to the basics again, without relying on Google.
nucleic acids are polymers of nucleotides, i.e macromolecules. these come in 2 flavors- ribonucleotides and deoxyribonucleotides, the difference being an OH or an H group on the ribose molecule within the nucleotide. If it is a polymer of the latter, then it is DNA. If the former, it is RNA. There are many kinds of RNAs with different functions. Viral RNAs encode genes, like our DNA does. mRNA is the carrier or messenger for the protein-code; it is transcribed from DNA, and is used by the ribosome to translate proteins. rRNA is the RNA component of the ribosome. tRNAs bring an amino acid to a specifc codon on the ribosome. Then there are “new” types that you will not find in a basic biology text-book, but of which researchers are becoming more aware of their importance: miRNA and siRNAs (short stretches of RNA that regulate gene expression), lncRNAs, snRNAs, asRNAs and many more.
