Question

cancer is due to uncontrolled cell production. what is the cause? 10 points excess sugar intake dna mutation too much caffeine an extra chromosome a mutation in the p53 gene has been linked to 10 points cancers in dairy cows. autism. obesity. over 50% of all cancers.

Explanation:

Cancer occurs when cells divide and grow uncontrollably. This is often due to changes (mutations) in the DNA that control cell growth. The p53 gene is a tumor - suppressor gene. When it mutates, it can't properly regulate cell growth, and this is linked to a large proportion of cancers. Excess sugar intake, too much caffeine, or an extra chromosome (like in Down syndrome which is trisomy 21) are not the fundamental causes of uncontrolled cell production in cancer. And the p53 mutation is mainly related to human cancers (not dairy cows), not autism or obesity.

Answer:

For the first question: DNA mutation.
For the second question: over 50% of all cancers.
