Why would it be impossible to extract dna from cooked foods?

1 answer:

7 0

DNA is bound together by covalent bonds between different molecules. It also contains proteins, which again are held together in their specific structures by covalent bonds.

Covalent bonds may be broken when high temperatures are applied. The temperatures that a food encounters during the cooking cause the DNA to be denatured, meaning it cannot be extracted. The same occurs with other proteins such as enzymes and antibodies.

tensa zangetsu [6.8K]

Answer:

The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.

Explanation:

Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.

The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.

Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.

lora16 [44]

Answer:

1. Improvements in telecommunication

2. Improvements in global travel

Explanation:

Global culture refers to the transmission of beliefs, values, and ideas around the world that has a significant impact in the behavior of society. This has been evolving through time, especially since the Industrial Revolution. Today, we are capable of communicating with other people as quickly and easy as ever in the history of humanity and this will keep evolving as technology evolves as well.

This evolution is due to science and technology, especially to the improvements in telecommunication, which enables us to communicate with people from other countries through calls, social media messagings, e-mails, etc., and to the improvements in global travel, which is much more accessible today than it was before, allowing individuals to move from one country to the other easily and constantly and improving socialization between people from different cultures and backgrounds.
