Answer:
Semi-conservative DNA replication:
The semi-conservative model of DNA replication explains that the newly synthesized daughter DNA molecule contains one newly synthesized strand and one parental strand. This model of replication is important and explains the biological significance of replication. The DNA unwinds in this mode of replication.
Conservative model of DNA replication:
The conservative model of DNA replication explains that the newly synthesized daughter DNA molecules has the one DNA helix of parent and the other DNA helix are entirely new. This model does not has a biological significance. The DNA is not unwinds in this mode of replication.
The semi-conservative mode of DNA replication is found in the living organism.
Individual
members of the same species are genetically very different because of a process
called meiosis which creates gametes.
<span>During
the meiosis (prophase I) the process called crossing over occurs. Crossing-over
represents the exchange of genetic material between non-sister chromatids of
homologous chromosomes which results in new combinations of genes on each
chromosome (genetic variation).</span>
An active transport is the process by which a substance is transported or transferred from one area to another using a chemical energy in the course.
<span>As oppose to passive transport, active transport’s key to its description uses energy to be able to transfer the said substance. This is important in a lot of aspects such as providing the needed elements or compounds in cellular activity.<span>
