. Jack and Jill are thinking about starting a family and they come to you with a question about a rare recessive genetic disease
cupoosta [38]

Answer:

The chance of  having a Child who is a Heterozygote  is 50% , The chance of having a child that will completely come down with Alpers syndrome is 0%

Explanation:

Jack  has a history of Alpers in his family

Jill has no history

lets assume Jack is a carrier : Ab ( because that is how he could have survived the first 10 lethal  years )

Jill : AA

Therefore the probability/chance of Jack and Jill having a child with Alpers ( carrier ) syndrome will be 50 % as shown below

AA * Ab = AA , Ab, AA, Ab

The child produced by Jack and Jill will only be a carrier of the syndrome and not completely affected by the syndrome

The formation of a cell plate is beginning across the middle of a cell and nuclei are re-forming at opposite ends of the cell. W
Kay [80]

Answer:

a. a plant cell undergoing cytokinesis

Explanation:

Cytokinesis is the process where the cytoplasm divides after mitosis to form two different daughter cells from the parent cell. Animal cell divides by just a cleavage formation. Plant cells have an additional step of formation of cell plate because they have cell wall.

At the end of anaphase and beginning of telophase when the two new daughter nuclei have just formed, cell plat formation begins. Secretory vesicles from golgi body come at equator of the dividing parent cell. These vesicles release all the materials required for cell wall formation. The materials start to form the cell plate which moves outwards till it reaches the division site of parent cell wall. Slowly cell wall arises from cell plate and cytokinesis occurs giving rise to new plant cells.

Why does coomassie brilliant blue r interact differently with different proteins?
alexandr1967 [171]
Dimethyl sulfoxide was found to be effective for extraction of Coomassie Brilliant Blue R-250 (Coomassie R) from stained proteins on polyacrylamide gel slices. A good correlation was found between the ability of different proteins to bind Coomassie R and their capacity for interaction with Coomassie Brilliant Blue G-250 (Coomassie G) in solution. Scatchard analysis showed that the number of Coomassie R ligands bound to each protein molecule is approximately proportional to the number of positive charges on the protein, about 1.5-3 dye.
