Which of what? What’s the rest
The genetic code is broken down into a series of codons on the mRNA. Each codon consists of 3 nucleotides which (normally) correspond to a single amino acid (e.g. AUG codes for methionine). I say normally because you can also have a codon indicate a stop codon (so no amino acid will be inserted and instead the polypeptide chain will terminate). This mRNA molecule with its list of codons will instruct a ribosome to synthesize a protein according to this code.
This code is the set of rules - based on the triplet or codon. This triplet code is universal - all organisms use the same codons to specify the placement of each of the 20 amino acids in a protein.
Answer/Explanation:
All cells are not the same because not all cells contain membrane-bound organelles.
Prokaryotic cells lack membrane-bound organelles. In contrast, eukaryotic cells contain membrane-bound organelles like an endoplasmic reticulum, lysosomes, and importantly, a nucleus.
The nucleus is where genetic information (DNA) is stored. However, it is only present in eukaryotic cells. Prokaryotic cells do not possess a nucleus, the DNA is found in the cytoplasm.
The correct answer for the question that is being presented above is this one: "Yes, because the observed changes in histone modifications are consistent with reduced transcription." The results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription because <span>the observed changes in histone modifications are consistent with reduced transcription.</span>
