Reorder

Order the following steps of translation

• Step ?-During translation, amino acids are assembled from information encoded in mRNA.

• Step ?- mRNA codons move through the ribosome, tRNA adds specific amino acids to the growing polypeptide chain.

• Step ?- The process continues until a stop codon is reached and the newly made protein is released.

Multiple Choice

Why is Central Dogma important for organisms and in particular humans?

• The Central Dogma is important because it explains how genetic information is translated into functional proteins, which are vital for all biological processes in organisms, including humans.
• It outlines the evolutionary history of species.
• It explains the process of photosynthesis in plants.
• It describes how proteins can replicate themselves without DNA.
