Epigenetics refers to a special kind of hereditary mechanism. Epigenetic changes do not change the DNA nucleotide sequence, yet

their effect on gene expression can last for several generations. In one surprising study, it was found that the grandsons of men who suffered a famine were less likely to die of cardiovascular disease. The experience of famine made some cardio-protective change in the sperm of those grandfathers that was passed on. What type of change was likely responsible?
A. histone acetylation or DNA methylation
B. Phosphatase levels
C. ubiquitin tagging

<u>Answer:</u>

The type of change that was responsible was “histone acetylation or DNA methylation”.

<u>Explanation:</u>

  • Histone acetylation is the process that involves the epigenetic adjustments that functions in the transcription process while regulating DNA.
  • Histone acetylation or DNA methylation is the major component of the gene regulation while passing from one generation to another.
  • The Acetyl groups are hooked up to lysine’s in histone tails so their charges play a vital role to avoid the histone tail to bind with the other molecules.

algol [13]

I think it's option four because as far as I know, red/green color blindness is an example of a recessive, sex-linked trait (encoded on the X chromosome), which results in much more men to suffer from it than women.

Hope that helps!

How do photosynthesis and cellular respiration contribute to the carbon cycle?
zheka24 [161]

Answer:

Carbon cycle may be defined as a type of biogeochemical cycle that regulates the amount of carbon in nature. The carbon is released by the living animals and utilized by the plants in form of carbon dioxide.

Photosynthesis consumes the carbon dioxide to make carbohydrates where as cellular respiration releases carbon dioxide and breakdown the carbohydrate. Both these process helps in recycling of the carbon in nature and maintains the level of carbon in nature.

Can you please help me!? ​

Answer:

You need to compare the location of bands for X and X's child. X is the mother, so the child will have half of all its bands from its mother, and the other half must be from the father. Some bands that X and X's child have in common are at around 185bp and 130bp (it is difficult for me to determine the exact position). Then look at the bands which X and X's child do not have in common. Those bands must have come from the father. So now you compare the remaining bands to all the bands of Megabucks and see if they match up. You can see a band at around 60bp that the child has. The mother did not have this band, so it must have come from the father. Megabucks does not have this band, so he is not X's father.

Explanation:

I hope this has helped you a little. The main thing to know is that a child's bands come from their mother and father, so if half the bands match up to the mum, the other half have to match up to some of the father's bands. But a child will never have the same set of bands as one of their parents - it will be a mix of both parents' bands.
