Cacao beans arrive in a factory from the areas where they grew. At the factory, the best beans are sorted and put into bags. Aft
Step2247 [10]

Answer:

See the answer below.

Explanation:

The arrival of cacao beans in the factory can be likened to the transcription of mRNA using a DNA template.

Sorting of the best beans at the factory can be likened to splicing process. During splicing, the introns are removed from the newly synthesized mRNA and the exons are joined together. The introns represent the non-coding portion of the mRNA while the exons represent the coding sequence.

The checking of bags by quality control can be likened to the final proofreading of the mRNA after splicing before being transported to the cytoplasm where they are used to synthesize proteins.

The large truck that transports the cacao beans represent the transport proteins that transport the mRNA to the cytoplasm while the chocolate-producing company represents the ribosome which is the site of protein synthesis.

Sometimes the snow does not completely melt and the partially melted snowflakes refreeze into snow pellets.:
