8 0

Answer:

Option (d).

Explanation:

Telomere may be defined as the repetitive DNA sequence present at the ends of the chromosomes. Telomeres consists of the nucleotide sequence rich in G and consists of vertebrate sequence  AGGGTT.

The mutation in telomerase enzyme can cause the excessive replication of the telomeres. These leads to the excessive cellular proliferation and makes the cell immortal. This extensive growth of telomere is one of the maine reason of the cancer development.

Thus, the correct answer is option (d).

Why are aseptic procedures important in Microbiology laboratory health care industry?
Sever21 [200]

Answer:

Aseptic technique is important in the microbiology laboratory health care industry because it reduces the contamination risk that can have serious implications on the health of a person.

If aseptic procedures are not performed in the Microbiology laboratory and health care industry then there would be chances of getting the disease because in health care industries pathogenic samples from patients are processed which can be transferred in the employee while processing if correct aseptic technique is not used.

Aseptic procedures include wearing lab coats and other protective suits while working which cover all body and give protection from entry of pathogens. Sterilization of surface where work is going on, proper sterilization of all pathogenic cultures.

Therefore aseptic procedures are important to avoid contamination in the microbiology laboratory.
