<h2>Mitotic Cell Cycle</h2>
Explanation:
a. Cytochalasin: an inhibitor of actin microfilament
- Cytokinesis is the process by which cytoplasm is divided into two cells hence generation of two daughter cells
- In animal cells the division of cytoplasm starts with the assembly of contractile ring
- Contractile band consists of actin and myosin and catalyze cleavage furrow formation
- Cytochalasin is a drug that blocks the polymerization of actin filament
- When cytochalasin is added dividing cell fails to undergo in cytokinesis due to defective assembly of contractile band
b. Colchicine: an inhibitor of microtubule formation
- Colchicine tightly binds with free tubulin dimer and prevents its polymerization
- In this case mitotic spindle apparatus do not assemble and cells unable to do partitioning of chromosomes into two groups
- Thus cell division is arrested
c. Aphidicolin: an inhibitor of DNA Polymerase activity
- Aphidicolin is used to induce cell cycle arrest via specific inhibition of DNA Polymerase α
- It blocks the cell cycle at early synthesis(S) phase
d. Emetine: an inhibitor of ribosome activity
- It blocks the protein synthesis in eukaryotic cells by binding to small subunit(40 S) of ribosomes
- It interferes with the synthesis and activities of DNA and RNA
Answer:
14.to 17 hours of a 24 hour period . say the national sleep faoundation , some newbourn sleep up to 18.to 19 hours a day
The lizard population on the chart shows it steadily increasing in numbers. This might be because there are less predators and they have more prey to feed on so that their population will thrive.
The homologous chromosomes pair with each other!
Answer:
The scientists could determine what are the risks to contract specific diseases, and also what are the chances of transmitting genetic disorders in next generations.
Explanation:
In this case, the scientists may determine what are the mutations that Jennifer could have and how these mutations are associated with diseases and/or genetic disorders
