If there is no oxygen...many cells die....but some can perform cellular respiration without oxygen too.....they are anaerobic. they usually use organic substance to survive !!!
as acidophilic bacteria survive without oxygen in acids ...so !!!
Answer:
Because the leading strand is synthesized continuously while the lagging strand is discontinuously synthesized.
Explanation:
Two DNA strands have opposite polarity, that is, the 5' end of one strand lies opposite to the 3' end of the other strand. However, DNA replication can occur in 5' to 3' direction only since the formation of phosphodiester bonds require the presence of nucleophile 3' OH to attack the 5' phosphate of an incoming deoxyribonucleotide.
The problem is solved by the synthesis of the leading strand continuously and the synthesis of the lagging strand in a discontinuous manner. Lagging strand synthesis requires the formation of primers and their elongation to form Okazaki fragments that may have few hundreds to few thousands of nucleotides. Removal of primers from Okazaki fragments is followed by joining them together to make the long lagging strand. The discontinuous replication of the lagging strand makes the replication at the leading strand ahead of it.
The island of Japan are the result of several large ocean movements occuring over hundreds of millions of years from the mid-silurian to the Pleistocene as a result of the subduction of the philippene sea plate beneath the continental amurian plate.
