An intron is a non-coding region of DNA. During alternative splicing, introns are removed.
- During eukaryotic transcription, a fragment of DNA (e.g., a gene) is used as a template to synthesize a complementary RNA sequence, usually a precursor mRNA (pre-mRNA).
- Subsequently, this pre-mRNA is processed by a mechanism called alternative splicing in order to produce a mature mRNA which is then used as template to synthesize a protein by a process called translation.
- During alternative splicing, non-coding regions of a gene called 'introns' are removed, where coding regions called 'exons' are spliced back together.
- If a cell transcribed and translated a gene’s intron by mistake, then additional amino acids would be inserted into the protein and therefore the resulting protein will be longer than normal.

Humans are creating antibiotic resistant bacteria through a process if <u>Recombinant</u><u> </u><u>DNA</u>
Leads to high pollution that makes global warming more dangerous
Except for the evolution of new diseases, because that’s bad, and it stops us I think, not sure though.
These are the answers:
Contact- 3. Extreme pressure deforms preexisting rock
Dynamic- 2. Magma hears preexisting rock
Regional- 1. Caused by pressure from a large scale geological event
Metamorphism is a change of the geological texture which is caused by heat, pressure, and the chemicals.
