When making a new protein, which rna type corresponds to the amino acids that are being linked together

Messenger RNA

Explanation:

Messenger RNA (mRNA) carries the genetic information from DNA as a series of nucleotides. The code  sequence is read consecutively in groups of three,  each of which specifies a particular amino acid.

Transfer RNA (tRNA) molecules translate the code and carry the appropriate amino acid to the end of the growing protein chain.  

Ribosomal RNA (rRNA) in ribosomes assembles the amino acids into protein chains.  

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.
