DENIUS [597]

Answer:

Extension

Explanation:

Polymerase chain reaction is given by Kary Mullis and it contains three steps denaturation, annealing, and extension. In denaturation, the temperature is raised to 96° c so that the DNA can denature.

In annealing, the temperature gets reduced to 55°c so that the primer can bind to the complementary sequence. In extension, Taq polymerase is used to extend the new strand.  

This enzyme is isolated from thermophilic bacteria and the temperature here is raised to 72°c so that the enzyme can extend the primer and make the complementary strand. So the right answer is extension.

zavuch27 [327]

Answer:

Earliest- gametophyte dominance, sporophyte dependence

Middle- sporophyte dominance, gametophyte independence

Recent-  sporophyte dominance, gametophyte dependence

Explanation:

The life cycle of plant alternates between the two phases: the haploid gametophyte which produces gametes and the diploid sporophyte which produces spores.  The evolution of land plants shows how these are dependent on each other in terms of the requirement of nutrition.

In bryophytes, the gametophyte is the dominant phase on which the sporophyte depended. Later in pteridophytes, the sporophyte became dominant which is present in the later evolved groups namely the gymnosperms and the angiosperms. The gametophyte was independent on the sporophyte but in angiosperms and gymnosperms, it is dependent.
