Answer:
Both (But choose True!)
Explanation:
When cells undergo mitosis, they go through a phase called interphase. This replicates their DNA. In meiosis, the same thing happens, but only to meiosis 1. In meiosis 2, DNA isn't replicated.
Thank you and have a great day!
These base pairs (adenine with thymine and cytosine with guanine) are significant because the rule allows a corresponding strand of DNA to be replicated. (New strand can be created with the template)
Mastication, or chewing, is a form of mechanical digestion that increases the surface area of foods prior to chemical digestion.
<span>CFCs and smog are examples of air pollution.
CFCs (containing atoms of carbon, chlorine and fluorine)are a component of aerosols sprays, refrigerants etc. These chemical compounds are non reactive in the lower atmosphere but the CFCs react with UV radiation in the sunlight and release inorganic chlorine. This chlorine is the main cause of the holes present in the ozone shield (shield that protects us from harmful UV rays) in the polar regions.
Smog refers to the haze or fog that occurs as a result of air pollution (caused by burning of fossil fuels etc)</span>
Answer:
The correct answer is option E. "DNA in both daughter cells would be radioactive".
Explanation:
Radioactive thymidine incorporation has irremediable effects in thymine and cytosine in bacteria such as E. coli. Although there are some reports of recovery of E. coli from UV-irradiation DNA damage, the presence of radioactive bases such as thymine is often irremediable. Therefore, after a dividing culture of E. coli exposed to radioactive thymine divides, DNA in both daughter cells would be radioactive.
