It is asking something and I took the quiz
Answer:
The need for DNA replication
DNA replication is the process by which a cell makes an identical copy of its DNA. This process is performed at the beginning of every cell division so that when the cell divides, each daughter cell will inherit an identical copy of the DNA.
Requirements for DNA replication
Original DNA template - DNA is a double helix made of two complementary strands. Each strand can be used as a template to create a new DNA molecule.
Free DNA nucleotides – needed to form the new strands.
DNA polymerase – an enzyme that adds new nucleotides to a growing strand of DNA.
Primers – A primer is a short strand of nucleotides that will bind to the 3’ end of the template DNA strand allowing DNA polymerase to add free DNA nucleotides.

A punnet square predict the traits of offspring genetic crosses and test crosses.
<u>Explanation:</u>
In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.
The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by genetic crosses.
In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.
