<h2><em>the DNA that is packaged into chromosomes must be fully copied. Previous to replication, a germ cell contains two copies of each chromosome, a maternal copy, and a paternal copy. ... DNA replication occurs in the same fashion as it does during mitosis.</em></h2>
Answer:
DNA can replicate itself because its two strands are complementary. This means that one strand can be used as a template to make the other strand. It happens right before cell division via mitosis or meiosis so that each new daughter cell can have a complete genome.
Before replication can start, the double strands of DNA need to separate from each other. An enzyme called DNA helicase breaks the hydrogen bonds that connect the two strands, allowing them to come apart.
The point where this unzipping starts is called an origin point. Eukaryotic DNA can have more than one origin point, but prokaryotes can only have one.
The points where DNA is currently unwinding are called replication forks.

There is a 50% probability that the flowers of a plant with pink flowers parents will have pink flowers due to incomplete dominance.
The genotypes and phenotypes that we will employ to address this issue are as follows:
RR - Red
RW - Pink
WW - White
They would have the RW genotype as the first parent plant is pink. They would have the WW genotype because the other parent is white. When the Pink flower parents are crossed, the children that might be expected from this cross
RW x RW
The progeny will be : 1 RR (Red), 2 RW (Pink) and 1 WW (White)
This shows that there is a 50% probability that the progeny will have the RW genotype and thus the pink phenotype. Additionally, we can observe that there is a 25% likelihood that the progeny will have the WW and RR genotype and the white and Red phenotype.

Explanation:
Earth's Orbit = 2*pi*R = 942,000,000 kilometers.
Distance/Time = 942,000,000 km / 8766 hr = 107,000 km/hr = 30 km/sec.
