In science models can show a process that’s difficult to observe directly using the style of the model shown draw the process that describes the rest of the steps in protein synthesis
According to the model presented below, after the transition the RNA is in a state called pre-mRNA where we can see the presence of exons and introns. Introns are not sequences of nitrogenous bases that can participate in the production of proteins and therefore are removed from the RNA molecule through a process called splicing. Once the introns are removed, the mRNA is ready and leaves the nucleus towards the cytoplasm, by a process called exportation. Reaching the cytoplasm, the mRNA in association with the tRNA and the ribosomes will give rise to a polypeptide chain, in a process called translation, where the nitrogenous bases are transformed into amino acids.
The polypeptide chain has a linear sequence of amino acids. This chain will undergo several folds in a process called folding, where it will form a three-dimensional structure, the protein.

Explanation:After the transcription of the DNA is complete, the genes encoding the amino acids for the proteins are copied onto the mRNA strand. After this, this RNA strand moves out of the nucleus. The ribosomes attaches the mRNA strand to itself and the tRNA reads the codon and brings the amino acid to the ribosome and attaches it. This process is continued till the protein is formed. This process is known as translation.
Hence, translation should be shown to complete the protein synthesis model.
when soaked in dilute sodium chloride solution onion gain mass because of the process of osmosis.
Explanation: Osmosis is a process when there is movement of water from the region of comparatively higher concentration to the region of lower concentration across in a permeable membrane.
