A.) An allele is a version of a gene that can be expressed as a phenotype.
<span>DNA polymerase is the enzyme that connects new nucleotides and proofreads them into separate DNA strands.
This process is part of DNA replication. A cell's DNA is replicated before a cell divides. The two strands of a DNA molecule have complementary base pairs. Each strand in the pair consists of a nucleotide sequence which is able to provide the information to duplicate itself. Before the duplication occurs, the length of the DNA that is about to be copied must be unwound and the two strands must be separated. This is done by breaking the weak hydrogen bonds that link the pairs together. They must then be kept apart from each other to expose the bases so that the new nucleotide partners can bond to them. DNA polymerase is the enzyme that moves along the exposed DNA strand and joins the new nucleotides to manufacture a new DNA strand that is a duplicate of the original</span><span>

Answer:
Alternation of generation with both sexual and asexual
Explanation:
In mosses, the dominant plant is called a gametophyte while in ferm the dominant is sporophyte. Gametes are produced by the gametophyte and fertilization occurs forming an embryo. The embryo develops into a plant called the sporophyte.
