Answer:
Prokaryotes do not have introns, eukaryotes have introns
Explanation:
Prokaryotes do not have introns, eukaryotes do. Introns are regions of DNA that are transcribed but not part of the final protein. They interrupt exons, which are the coding parts of the gene. These are only present in eukaryotes.
Introns need to be removed before the mRNA can be translated into the protein sequence. This occurs by a process called splicing. The splicing machinery binds the junction between introns and exons and excises the intron. The exons are then fused together to create the mRNA.
Other processing steps occur to the eukaryotic pre mRNA to prevent it from being degraded in the cell. This includes adding a cap to the 5' end of the protein, and adding a poly A tail to the 3' end. One these steps are complete, the eukaryotic mRNA is complete.
The prokaryotic mRNA undergoes transcription and translation simultaneously because it doesn't require these processing steps.
Answer:
How does biology change the way we think about life? - If plants didn’t produce their own food, you wouldn’t have anything to eat. So the next time you sit down to eat, you can thank the process of photosynthesis for your food.
Why is agriculture equally important to the other sciences? - Early farmers improved their crop production by inventing the first gardening tools. Today, farmers improve crop production through the use of Global Positioning Systems aka GPS. Agriculture is just as important, we need all of the new and old sciences.
