Answer:
False
Explanation:
When transcription is complete, the resulting RNA molecule is called a pre-mRNA (precursor mRNA). This pre-mRNA undergoes several modifications before it becomes a mature mRNA that is ready to be sent to the ribosome for translation. The modifications include:
5' Capping: A special nucleotide called a 5' cap is added to the 5' end of the pre-mRNA to protect it from degradation and help in the recognition by ribosomes during translation.
3' Polyadenylation: A long string of adenine (A) nucleotides, known as a poly-A tail, is added to the 3' end of the pre-mRNA. This tail helps to stabilize the mRNA and aids in its export from the nucleus to the cytoplasm.
Splicing: The pre-mRNA contains both coding regions (exons) and non-coding regions (introns). During splicing, the introns are removed, and the exons are joined together to form a continuous coding sequence. This process results in a mature mRNA.
Only after these modifications is the mRNA considered to be in its final form and ready to be transported to the ribosome for translation.
