Question

model 2 – translation
initiation
elongation
termination

1. refer to model 2.

a. what are the three stages of translation?
b. define each of the terms used in your answer to part a as they are used in everyday language.

Explanation:

Part a

The diagram (Model 2) for translation shows three labeled stages: Initiation, Elongation, and Termination. By observing the labels on each section of the model, we can identify these three stages as the key phases of translation.

• Initiation (everyday language): It is the starting or beginning phase of a process. In the context of translation, it's when the components (like ribosome, mRNA, tRNA) come together to start the protein - building process, similar to how a project or task is initiated (begun) in daily life.
• Elongation (everyday language): It means the process of making something longer. In translation, during this stage, the polypeptide chain (protein - in - making) gets longer as more amino acids are added, just like a rope being elongated (made longer) by adding more strands.
• Termination (everyday language): It is the act of ending or bringing to a stop. In translation, this is when the protein - building process stops, similar to how a meeting or a journey can be terminated (ended).

Answer:

The three stages of translation are Initiation, Elongation, and Termination.
