In prokaryotes the 5' UTR is 3-10 nucleotides.
In Eukaryotes the 5'UTR is 100 to many thousand nucleotides long.
Explanation:
Leader sequence or 5' UTR starts at transcription site and ends at the initiation codon just one nucleotide away from it.
It is present in mRNA.
These are GC rich and form secondary structure, helps in protein synthesis.
Shine Dalgarno sequence in prokaryotes is an example of 5'UTR.
It acts as an entry point of ribosome.
B.
All dentist equipment is used in the mouth. Many deseases, bacteria and viruses are transmitted trough saliva, and not all of these are weak. So, that is why we clean the dental operatory, to lower the chances of transmitting anything.
