Question

the codon (set of 3 nitrogen bases) codes for 1 of 20 rna endoplasmic reticulum genes amino acids

Explanation:

In molecular biology, codons (three - nucleotide sequences in mRNA) are the basic units of the genetic code. The genetic code is a set of rules that determines how nucleotide sequences in mRNA are translated into amino acids. There are 20 standard amino acids that are the building blocks of proteins. Each codon (except for stop codons in most cases) codes for one of these 20 amino acids. RNA is a nucleic acid involved in various processes like transcription and translation. The endoplasmic reticulum is an organelle involved in protein and lipid synthesis. Genes are segments of DNA that contain the instructions for making proteins (among other things), but it is the codons (in mRNA, which is transcribed from DNA) that directly code for amino acids.

Answer:

amino acids
