Answer:
Are not affected by disease or bleaching.
Explanation:
A healthy coral shows shades of olive green, brown, tan and pale yellow. A healthy coral in a host of many species of tropical animals, some others find their food that shelters in the crevices of stony corals. Abnormal paling color is a bad sign in corals when they are stressed out and they begin to bleach. when this happens the edge of the affected tissue turns from light to dark, in comparison to disease where the difference between healthy and diseased tissue is seen as a distinct line. There are many diseases that cause coral's abnormal bleaching color. for example, white band, white botch, coprophilia, and others.
Answer:
C. to address the ethical consequences of genomic research
Explanation:
Option A comes very close to the correct answer but is not the main goal. Although the scientists were after decoding our genome and mapping our genes and such, ultimate goal was also to address the ethical consequences of genomic research because your genome is your blueprint (i.e. your genome makes you).
Answer:
c. 20 minutes three times a week

Answer:
to add nucleotides to a DNA primer
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology in order to amplify small segments of DNA (100 to 1000 bases). PCR uses a thermostable DNA Taq polymerase that adds nucleotides to the DNA template at the position specified by short single-stranded DNA primers that bind to this template by complementary base pairing during the annealing phase of the PCR cycle. Subsequently, the DNA polymerase adds deoxynucleotide triphosphates (dNTPs) to the opposite DNA strand, this phase of the PCR cycle is known as the elongation phase. Finally, the resulting double-stranded DNA fragment is separated by heat during the denaturation step and this 3-step PCR cycle is repeated many times to amplify the target DNA region.
