Normally a 10× drop for each trophic level, so I'd say 2,000 kilocal.
The statement that is true about exons and introns of pre-mRNA is:
- Exons are expressed, and introns are removed.
<h3>What is pre-mRNA?</h3>
Precursor mRNA or pre-mRNA is the first transcript of a protein-coding gene.
<h3>Characteristics of pre-mRNA</h3>
- Introns are the DNA or RNA sequences that separate the exons, the pre-mRNA regions corresponding to these are eliminated in the nucleus during the maturation process.
- The exons of a gene are the sequences that will give the messenger RNA that will be translated into amino acids.
Therefore, we can conclude that the pre-mRNA maturation process removes introns and joins exons to produce a mature messenger RNA molecule.
