What is the significance of the 5' cap and poly-A tail in mRNA?

Step 1: Understand that mRNA is a type of molecule that carries genetic information from DNA to the ribosomes, where proteins are made.
Step 2: Learn that the 5' cap is a special structure added to the beginning of the mRNA molecule.
Step 3: Know that the 5' cap helps protect the mRNA from being broken down by enzymes in the cell.
Step 4: Recognize that the 5' cap also helps the ribosomes recognize and bind to the mRNA for translation.
Step 5: Understand that the poly-A tail is a string of adenine nucleotides added to the end of the mRNA molecule.
Step 6: Learn that the poly-A tail also protects the mRNA from degradation and helps in the export of mRNA from the nucleus to the cytoplasm.
Step 7: Know that both the 5' cap and poly-A tail are important for the stability of mRNA and for making sure proteins are produced correctly.
