Chicken skin bumps â such a simple yet instantly identifiable description of the skin problem named keratosis pilaris (commonly dubbed KP).
Semiconservative model. One strand of the parental duplex remains intact in daughter strands (semiconserved); a new complementary strand is built for each parental strand consisting of new molecules. Daughter strands would consist of one parental strand and one newly synthesized strand.he enzyme that actually matches the existing DNA bases with complementary nucleotides and then links the nucleotides together to make the new strand-All DNA polymerases that have been examined have several common features: 1.) They all add new bases to the 3' end of existing strands.
Because each parental strand serves as the template for. one new strand, each of the daughter DNA double helices ends up with. one of the original (old) strands plus one strand that is completely new; this style of replication is said to be semiconservative (Figure 6â3).
