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.
The process is called Cytokineses.
The process that was likely affected due to the incident wherein his nail gun has been discharged into his frontal lobe is that his personality and behavior has changed because the part of the frontal lobe that has been affected is the left side. In which is responsible for the behavior and personality of an individual.
Answer:
The presence of an additional chromosome
Explanation:
Look at "pair" 21. See how there are THREE chromosomes instead of TWO? Normally, there would only be two chromosomes in each pair but this karyotype shows a trisomy (see def. below) of the 21st pair. This was caused by a nondisjunction mutation of the 21st pair. The is also the karyotype of a person with Down's Syndrome.
Definition of Trisomy:
A condition of the presence of three chromosomes in a pair instead of two. This normally causes developmental irregularity.
