75% of the children will have the probability of being tasters. 25% will have the probability of being non- tasters.
Answer b)
There will be a 75% chance that their first child or their fourth child will be a taster.
The chances for every child will be the same because alleles assort independently during the time of gamete formation. Hence, the probability remains the same every time.
Answer c)
There will be a 25% chance for the first three offsprings to be non-tasters. 75% chances will be of them being tasters.
This is because the alleles assort independently each time during gamete formation. Hence, the chances will be the same every time.
The two enzymes that are used during DNA replication is helicase
and polymerase. Each enzyme has distinct role that made it a vital part of the replication.
In the course of DNA replication, the initial stage is to unzip the double
helix structure of the DNA molecule by the enzyme helicase, which breaks the
hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a
DNA template. This enzyme binds to the leading strand and then adding a new
complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of
deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.

Ptolemy was an astronomer and mathematician. He believed that the Earth was the center of the Universe. The word for earth in Greek is geo, so we call this idea a "geocentric" theory.With the development of the heliocentric model by Nicolaus Copernicus in the 16th century, the Sun was believed to be the center of the Universe, with the planets (including Earth) and stars orbiting it.
