mRNA Processing and RNA Types Daily

An enzyme which cuts out portions of mRNA that are not needed.

• Intron

• Exon

• Protective End

• Spliceosome

A portion of mRNA that is kept to translate into a protein

• Intron

• Exon

• Protective End

• Spliceosome

A portion of mRNA that is not needed to make a protein and is thus cut or spliced out.

• Intron

• Exon

• Protective End

• Spliceosome

Added after mRNA editing to keep the structure safe from RNAse destruction.

• Intron
