Telomeres are DNA repeats at the ends of chromosomes, which are used to maintain the integrity of chromosomes. Each time DNA is copied, telomeres are shortened a bit. Once telomeres are exhausted, chromosomes are susceptible to mutation and cause arteriosclerosis or susceptible This is a type of cancer that some have speculated to be able to calculate human life using the length of telomere DNA. Which of the following, if true, would most weaken the above speculation? ['Experiments have shown that telomere length is related to aging and related diseases in people over 60 years of age, but it is not related to young people.', 'The use of telomeres for the "length of life" test will bring a sense of internal tension and anxiety to the subject, and the results may raise related ethical issues.', "The study found that the length of a person's initial telomere DNA has been determined from birth, and there is great shame due to different people. The maximum length can reach 20,000 alkali plug pairs, and the shortest is only 3,000. Base pair.", 'Blood sample telomere DNA analysis is a commonly used analysis method in laboratories, which requires a large amount of blood, takes time and effort, and the accuracy of the measurement is greatly affected by the level of technology.']
