The polymerase chain reaction relies upon unusual, heat-resistant that were isolated from bacteria living in hot springs

The right words to fill the blank are DNA POLYMERASE ENZYME.

Explanation:

DNA polymerase chain is a method used in molecular biology to produce abundant copies of specific DNA segments. The process is catalyzed by an enzyme called DNA polymerase. The DNA polymerase enzyme is usually isolated from bacteria, which live in hot spring. One good example of such bacteria is Thermus aquaticus. The DNA polymerase isolated from this particular bacterium is usually preferred because it is heat stable and produce DNA strands at faster rates compared to natural DNA polymerase.

hello there,

igneous rock formed from below the surface would have more crystals because

answer: because magma cools more slowly than lava

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
