Introns and Exons
Q1: What is the main difference between introns and exons?
Answer:
The introns and exons can be differentiated on the bases of coding amino acid sequences during protein translational process. Exons are the coding sequences which codes for amino acid sequence during protein synthesis, whereas the introns are intervening non-coding sequence which gets removed during the process of post transcriptional modifications.
Q2: What are the two functions of introns?
Answer:
Following are the functions of introns
- Involved in the regulation of alternative splicing
- Makes eukaryotic mRNA a polycistronic mRNA
Q3: What are introns made of?
Answer:
The introns are as same as exons made up of nucleotide sequences but do not code for the protein sequences as they are removed during the process of post-transcriptional modifications.
Difference Between Introns and Exons
Difference Between Introns and Exons: Introns and Exons are the integrated part of the eukaryotic genome. Introns are intervening non-coding nucleotide sequences whereas the exons are the amino acid coding sequences.
We have seen various evolutionary changes from the prokaryotes to the eukaryotes. The eukaryotic cells have become more advanced and organised as compared to prokaryotes. Although prokaryotes have a higher tendency to evolve faster than eukaryotes, but the level of complexity in a eukaryotic cell is unmatchable.
