SUMMARY

The discussion centers on the nucleotide sequence from 1 to 1430, specifically analyzing the locations of the 5' and 3' untranslated regions (UTRs) in relation to the gene, mRNA, and coding sequence (CDS). The gene spans from 606 to 1430, with the mRNA and exon both ranging from 606 to 1170, while the CDS extends from 990 to 1170. The correct identification of the 5' UTR is from 606 to 990, and the 3' UTR is from 1170 to 1430, although it is clarified that the 3' UTR cannot extend beyond the mRNA's endpoint at nucleotide 1170.

PREREQUISITES
  • Understanding of nucleotide sequences and their components
  • Knowledge of gene structure, including exons and introns
  • Familiarity with mRNA processing and UTR definitions
  • Basic concepts of coding sequences (CDS) in molecular biology
NEXT STEPS
  • Study the role of 5' and 3' UTRs in gene expression regulation
  • Learn about mRNA processing and its implications on translation
  • Explore the significance of the coding sequence (CDS) in protein synthesis
  • Investigate tools for visualizing nucleotide sequences and gene structures
USEFUL FOR

Molecular biologists, geneticists, and students studying gene expression and mRNA structure will benefit from this discussion.

Suppose we have a sequence of nucleotides 1 - 1430.

The gene is from 606 - 1430.
The mRNA is from 606-1170. So is the exon (i.e. its 606-1170).
The CDS is from 990-1170.

What would be the location of the 5' and 3' UTR's?

I think the 5' UTR would be 606-990 and the 3' UTR would be 1170-1430 respectively.

Correct?
 
Biology news on Phys.org
The 3' UTR is part of the mRNA, so 1170-1430 cannot be the 3'UTR if the mRNA ends at nucleotide 1170.
