When there has been an error in copying a DNA, a DNA repair gene fixes its mistakes. However, a person having an error in his DNA repair gene (which are not corrected), it may lead to gene mutations with the possibility of leading to cancer. The mutations of DNA repair gene can possibly be inherited or acquired.
Answer: unfavourable ph condition for the pepsin
Explanation: during digestion, enzymes are needed to aid the process.digestive enzymes are biological catalyst that breakdown large food particles into digestible form .
As biological catalyst, enzymes require an optimum temperature and pH condition.outside this temperature or pH,the enzyme is denatured.
In the stomach, hydrochloric acid is required to convert pepsinogen into it's active form,pepsin.the acid also creates an optimum low pH that pepsin needs to function.
As the food moves to the small intestine,the pH is alkaline and is unfavourable for pepsin to function.
Answer:
No
Explanation:
<u>That a gene is common to all murderers in the population does not mean that murderers are not at fault for their crimes. </u>
<em>Having a gene that correlates with murder just gives one a genetic tendency but the environment and personal choice still have to influence the decision to commit the crime. In other words, one might have the genetic tendency to commit murder but still has to be environmentally enabled and the ability to choose to either do it or otherwise. Nature, nurture, and personal choice would have to synergistically work together for the phenotypic expression of such a gene. </em>
