Answer:
D
Explanation:
<u>Sister chromatids</u> will have the same form of alleles at the locus after S phase.
<em>This is because during the S phae of the cell cycle, sister chromatids are replicated in preparation for cell division. The replication process is quite accurate such that all the alleles present on the initial chromatids are also replicated on the new sister chromatids. Hence, both new and old chromatids will have the same form of alleles at the locus after replication at the S phase. In other words, sister chromatids are exact copy of one another.</em>
The correct option is D.
Answer:
Socrates will always question any man with a reputation for wisdom. He wanted he/she to examine his/her live and become aware of their own ignorance rather than thinking that they know things when actually they know nothing.
The three classes of people Socrates questioned were the politicians, Poets and craftsmen.
He found all three lacking in the real wisdom (Higher Things or Human Excellence) as they only possessed human wisdom in their respective trades.
Answer:
P53, EGFR and KRAS genes
Explanation:
Mutations on somatic cells will disturbs the cell cycle and induce cell proliferation which lately results in tumour formation. The mutated P53, EGFR and KRAS genes causes lung cancer. P53 has direct contact with DNA acts a suppressor of tumour and guards the cell divisions. When these genes are mutated they induce expression of different genes (especially P53) leading to lung cancer.
