Here's why:
* mRNA is essential for protein synthesis in all living organisms. All organisms, including plants and animals, use mRNA as the intermediary molecule that carries the genetic code from DNA to the ribosomes, where proteins are made.
* The fundamental process of protein synthesis is remarkably similar across all life forms. This includes the roles of mRNA, tRNA, and ribosomes.
The differences between plant and animal protein synthesis lie more in the details of the process and in the specific proteins produced, rather than the core mechanism itself.
Here are some key differences between plant and animal protein synthesis:
* Plant cells have chloroplasts, which have their own DNA and protein synthesis machinery. This means that plants have two distinct systems for protein synthesis.
* Plants often have different sets of amino acids used in their proteins. This reflects their unique metabolic pathways.
* Plants have a higher proportion of proteins involved in photosynthesis and other plant-specific functions.
In summary, while there are differences in protein synthesis between plants and animals, the use of mRNA is a universal characteristic of all living organisms and is not a distinguishing feature between the two kingdoms.
