Answer:
Pleiotropy
Explanation:
Pleiotropy is a genetic condition in which a single gene conditions the expression of multiple phenotype. There are different types of pleiotropy depending on the underlining mechanism
- <em>gene pleiotropy</em>
- <em>developmental pleiotropy</em>
- <em>selectional pleiotropy</em>
- <em>antagonistic pleiotropy </em>
<em>Phenylketonuria is a disease characterized by increased level of amino acid phenylalanine in the blood. It caused by mutation to the gene responsible for breaking down phenylalanine in the blood. Elevated level of phenylalanine causes other issues such as mental problems, urine coloration and reduction in skin pigmentation. This is a clear case of pleiotropy.</em>
Answer:
Nucleation
Explanation:
The first step of formation of new phase, structure or self-assembly is called as Nucleation.
It is mentioned in the book of Molecular Biology of the Cell that whenever, In-vitro polymerization of micro-tubules and actin filament occur the first step is called nucleation. In other words Lag Phase.

Answer:
1) Break down of the nuclear membrane allowing mitotic spindles to connect to kinetochores:A. Metaphase
2)APC degrades securin which allows separase to become active which degrades the cohesin rings: E. Anaphase
3) Dephosphorylation of nuclear pore and lamins: F.Telophase
4) cleavage of plasma membrane by actin and myosin contractile ring:D.Cytokinesis
5) copying of the genome:C. Interphase
6) formation of the metaphase plate:B. Prometaphase
