USPshnik [31]

Answer: Experiment.

Explanation:

Suppose that we have two related variables, A (independent) and B (dependent)

We could design an experiment where we can manipulate the value of A at will, and we also can observe how the variable B changes.

This is called an experiment, where the objective is to see how the variable B is related to the variable A, and then try to make a model that explains this relationship.

Which best summarizes the process of protein synthesis?
Tpy6a [65]

Answer:

RNA moves the DNA code to the ribosomes for protein synthesis

Explanation:

Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins. In translation, a cell decodes the mRNA genetic message and assembles the brand-new polypeptide chain. tRNA, translates the sequence of codons on the mRNA strand. The main function of tRNA is to transfer a free amino acid from the cytoplasm to a ribosome, where it is attached to the growing polypeptide chain. tRNAs continue to add amino acids to the growing end of the polypeptide chain until they reach a stop codon on the mRNA. The ribosome then releases the completed protein into the cell.
