Base excision repair (BER) differs from nucleotide excision repair (NER) in which of the following ways?

Biology
1 answer:
postnew [5]3 years ago
7 0

The correct answer is:  5) NER recognizes helix distortions, while BER recognizes specific base damage.

DNA damage that occurs as a result of radiation, oxidizing reagents, chemicals and other mutagens can be repaired. Excision repair repairs single strand DNA damage and it includes:

• Nucleotide excision repair (NER)-it detects and repairs types of damage that distort the DNA double helix such as those of UV radiation (thymine dimers); not only the damaged nucleotide(s) are removed but also a surrounding patch of DNA

• Base excision repair (BER)-it detects and removes certain types of damaged bases (small, non-helix-distorting bases); enzyme glycosylase is responsible for this type of repair

The following health statistics are available on the Internet for country Z about two disease outcomes. Disease A has an annual
Citrus2011 [14]

The burden of diseases A and B in country Z is that disease B has a higher prevalence than

disease A. That is option D.

<h3>Health statistics of Country Z</h3>

Health statistics is used by professionals to summarize the health status or information on the health of individuals in a particular geographical location.

The basic statistic tools that can be used to check the health status of a population are,

  • prevalence

  • Case fatality ratio

The prevalence rate is the total number of cases of a disease existing in a population divided by the total population.

The prevalence rate of disease A = 225 per 100,000 population while the prevalence rate of disease B = 500 per 100,000 population.

Therefore, the burden of diseases A and B in country Z is that Disease B has a higher prevalence than

disease A.

During photosynthesis, oxygen is converted to carbon dioxide. True False
andreyandreev [35.5K]
This is false. Carbon dioxide is taken in, and oxygen out. Oxygen is not converted to carbon dioxide. It is a waste of the chemical reaction taking place, just like carbon dioxide is a waste in the respiratory process for us.

I hope this helps!
