Even before the structure of DNA was elucidated, experimental evidence indicated that the hereditary material had to have three key properties. Choose a correct combination of the options : a. must allow faithful replication. b. must have informational content. c. must be able to change on rare occasions. d. must be in the nucleus. e. must be degenerate

The correct combination for the 3 key properties is:

a. must allow faithful replication.

b. must have informational content.

c. must be able to change on rare occasions.

Explanation:

Since every cell in one particular body essentially contains the same DNA, it has to be copied accurately every time a cell divides. The information that the DNA codes for is the proteins that get translated and accounts for every feature that organism will have. These rare changes are known as mutations and they are critical to introducing variation in the species and allowing them to evolve in response to environmental stimulation.

Hope that answers the question, have a great day!

d

explanation:

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
