1. DNA replication produces two identical DNA molecules, called sister chromatids, which separate during mitosis.
2. After chromosomes condense, the centromeres is the region where the identical DNA molecules are most tightly attached to each other.
3. During mitosis, microtubules attach to chromosomes at the Kinetochores.
4. In dividing cells, most of the cell's growth occurs during Interphase
5. The mitotic spindle is a cell structure consisting of microtubules, which forms during early mitosis and plays a role in cell division.
6. During interphase, most of the nucleus is filled with a complex of DNA and protein in a dispersed form called ,chromatin.
7. In most eukaryotes, division of the nucleus is followed by cytokinesis, when the rest of the cell divides.
8. The centrosomes are the organizing centers for microtubules involved in separating chromosomes during mitosis.
Complete question:
In the US, 1 in 1700 Caucasian children will be born with the monogenic hereditary disorder Cystic Fibrosis (CF), a pathology that results in an accumulation of abnormally sticky and thick mucus affecting the lungs and digestive system. Consider a small isolated community in Appalachia where most of the population lives below the poverty level and where adults have a higher rate of CF that the national average since the people tend to marry neighbors. The general practitioner for the county receives a Bill and Melinda Gates Foundation Grant to ascertain how many children in the community inherited cystic fibrosis from their parents. Out of 172 children tested, she finds 38 have CF. Remember that Mendel believed in diagnostic ratios for understanding inheritance outcome although other factors can come into play like assortative mating.
Based on the testing outcome, give your opinion on whether you think Cystic Fibrosis is a dominant or recessive disorder.
A.Probably dominant.
B.Probably recessive.
C. Neither
D. Not enough information
Answer:
B. Probably recessive disorder

Answer:
Emulsifies fat, keeping tiny fat droplets suspended in the aqueous contents of the gut
Explanation:
- Bile emulsifies fat, keeping tiny fat droplets suspended in the aqueous contents of the gut.
- Bile juice is a fluid that is secreted from the liver and stored in the gall bladder. The juice helps in the emulsification of fats or break down of fats into simple fat droplets.
- The simple fat droplets from emulsification can then be absorbed in the small intestines through the lacteal.
