In which year did Elizabeth Blackburn co-discover telomerase?
1984
1978
1992
2001
Answer
In 1984, Elizabeth Blackburn, along with Carol Greider, co-discovered telomerase, an enzyme responsible for maintaining the length of telomeres, the protective caps at the ends of chromosomes. Telomerase prevents telomeres from shortening with each cell division, which would eventually lead to cell death. This discovery has significant implications for understanding aging and cancer, as telomere shortening is associated with both processes.
