The answer is ribosomes.
The ribosome is the molecular machine inside the cell that makes protein from amino acids in a process called translation. It binds to a messenger RNA (mRNA) and reads the information contained in the sequence of bases of the mRNA.
Transfer RNAs (tRNAs) containing amino acids enter the ribosome in a special pocket or binding site, called the acceptor site (A site). Once correctly bound, the ribosome can add the amino acid on the tRNA to the growing protein chain, linking each amino acid to another with pin point accuracy.
Option A, The pressures of a hatchery environment and of the wild environment select for different traits.
The various pressures in wild environment include the competition for food and survival, threat of prey etc. The effect of domestication on salmon can also be a reason for its low productivity in wild environment. Some other factors that might have affected the regular productivity of salmon in wild environment include- captive rearing, inbreeding among close relatives and ability of some fish to adapt to the unique hatchery environment.

<span>Proteins that are involved in the packaging of eukaryotic chromosome into "beads" called nucleosome are histones.</span>
A nucleosome is a segment of DNA wound in sequence around eight proteins called histones. Together the DNA and the histones form "beads"
A nucleosome is the basic unit of DNA packaging in eukaryotic cells.
