DNA replication can also be performed in vitro (artificially, outside a cell). DNA polymerases isolated from cells and artificial DNA primers can be used to initiate DNA synthesis at known sequences in a template DNA molecule.NA replication can also be performed in vitro (artificially, outside a cell).

Average temperatures in the Antarctic interior get down to -70 degrees Celsius during the winter months and -35 degrees Celsius in the warmer months.   The coastal te â¦ mperatures are much warmer with a range of -15 to -32 Celsius in Winter and -5 to +5 Celsius in Summer.
How cold is it? Antarctica is the coldest continent on earth. The farther from the coast one goes the higher and colder it becomes. In most coastal regions the mean annual temperature is around â12Â°C, at 1000 metres â20Â°C, and in the highest parts near 4000 m it falls to â60Â°C.
