In the process of the nitrogen cycle. <span>
The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA. </span><span> </span>
Answer:
c. Proteins
Explanation:
A stretch of DNA that code for specific proteins is said to be a gene. A gene is transcribed into mRNA. The mRNA has a nucleotide sequence complementary to the corresponding gene. The nucleotide sequence of mRNA is read in the form of genetic codes during the process of protein synthesis to specify the amino acid sequence of proteins. Therefore, genes carry the genetic information for the assembly of proteins and the processes of transcription and translation deliver the stored genetic information.
Ans.
Tuberculosis (TB) is a bacterial infection that affects mainly respiratory tract and can be transmitted from one to another person through contaminated air. The causative agent of tuberculosis, <em>Mycobacterium tuberculosis</em> has developed resistance against many antibiotics, such as rifampin and isoniazid, which is known as tuberculosis drug resistance.
If a person infected with TB shows drug resistance against some TB drugs, 'doctors should give other TB drugs to that person, even if these drugs show less effect than common drugs'. This is because these drugs can prevent or kill the bacterium more effectively than the common drugs for which, bacterium is resistance.
