Question:
Why is the mRNA of eukaryotes protected much more so than that of bacteria?
Answer:
Eukaryotic mRNA is more protected because eukaryotic cells are larger and more complex, so mRNA needs to last longer to make enough protein before it's broken down.
Question:
The nucleotide sequences on the ends of chromosomes that protect the genome from nucleolytic degradation, unnecessary recombination, repair, and interchromosomal fusion are called...

Telomeres

Question:
True or False:
The nucleotide sequences on the ends of chromosomes that protect the genome from nucleolytic degradation, unnecessary recombination, repair, and interchromosomal fusion are called telomeres.
Answer:
True
Question:
Why do scientists believe that telomere shortening has a strong correlation with aging?
Answer:
Scientists believe telomere shortening is linked to aging because, over time, it leads to chromosomal damage. This triggers cell senescence, where cells function poorly, contributing to aging-related changes in the body.
