Answer:
Regarding translation the following statements is <u>false</u>: The mRNA strand is read from 3' to 5' direction during translation.
Explanation:
The <em>primary structures</em> for protein synthesis are the ribosomes, organelles composed by the <em>association of proteins with rRNA and tRNA</em>. During translation, mRNAs are read in the 5´ to 3´ direction, and tRNA transfer amino acids to build the polypeptide chain. The <em>protein is synthesized</em> from the amino terminus<em> to </em>the carboxy terminus. Each amino acid is <em>specified by a </em>codon formed by three bases in the mRNA. mARNs have a<em> </em>start and end codon that tells the ribosome where to start and stop adding amino acids. When the ribosome reaches the end codon, it means that protein synthesis is finished.
