Eukaryotic messenger RNA undergoes several processing steps
after transcription before it binds to ribosomes as the template
for protein synthesis. One of these steps is polyadenylation.
Identify whether the statements below about polyadenylation are
true or false.
1. A polymerase adds the polyadenylate tail to the mRNA after it has entered the cytoplasm. 2. A polymerase adds a polyadenylate tail of up to 250 nucleotides to the 3 end of the mRNA. 3. The polymerase forming the polyadenylate tail uses a polydT DNA. template strand. 4. The polyadenylate tail helps to protect the mRNA from exonucleases. 5. Polyadenylation can occur before or after the mRNA is spliced. The mRNA for what eukaryotic proteins are not polyadenylated? Select answer false
