Why are onion root tips a good choice for viewing cells in different stages of the cell cycle?
The onion root tips are good for observing cells in different stages of cell cycle as they comprise of different cells in different stages of growth and development.
The onion root tip is an actively growing region of the onion plant. The cells are expected to be in different stages of growth and maturation. The cells are in different stages of mitosis which can be observed microscopically. The onion root tip can be prepared for microscopic examination by squashing and flattening of the onion root tip. The chromosomes during different stages of mitosis can be observed by using staining with specific dyes like Feulgen stain and Acetocarmine stain.Learn more about cell cycle:

Suppose the 3' splice site is mutated from AGG to ACG. Predict the consequence of this mutation. Choose one: A. Splicing would occur as normal because this splice site is less important than the 5' splice site. B. Splicing would occur as normal but there would be a point mutation in the mRNA and final protein sequences. C. Splicing would not begin if the 3' splice site is altered. D. Splicing would begin but not be properly completed if the 3' splice site is altered.
Solution :
The correct order of the RNA splicing is :
1. The BBP and the U2AF is to bind the A in branch point site in the intron, but the U1snRNP binds the 5' splice site.
2. U2snRNP helps to bind the branch point site while U4/U6 and the U5snRNP binds the 5' slice site.
3. 5' end of intron binds branch point adenine and forms a lariat.
4. Conserved adenine in branch point site attacks 5' splice site thus cutting the RNA at 5' splice site.
5. Lariat is released and then degraded.
6. The 3' end of first exon interacts with 3' splice site and forms a new bond in the sugar phosphate backbone.
When the 3' splice is altered, then the splicing begins but are not properly completed due to the altered activity of the full introns that will be present in mRNA.

In Drosophila, the genes for eye color, wing shape, and wing length are located on chromosome II. Purple eyes (pr), arc bent wings (a), and vestigial wings (vg) are the mutant forms of the wild type traits red eyes, straight wings, and long wings, respectively. You've discovered some data in your genetics laboratory which indicates that the distance between vg and pr is 12.5 m.u., the distance between a and pr is 44.7 m.u., and the distance between a and vg is 32.2 m.u. what is the chance of a double crossover between these three genes
Answer:
The expected double recombinant frequency = 0.0402 = 4.02%
Explanation:
Available data:
genes for eye color, wing shape, and wing length are located on the same chromosomePurple eyes (pr) is the mutant form of the wild type traits red eyes (pr+)Arc bent wings (a) is the mutant form of the straight wings (a+)Vestigial wings (vg) are the mutant forms of the long wings (vg+)the distance between vg and pr is 12.5 m.uthe distance between a and pr is 44.7 m.uthe distance between a and vg is 32.2 m.u→ Two genes that are very close will have a few recombination events and are strongly bounded.
→ The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.
1) First, we need to know their order in the chromosome, and to do so, we need to compare the distances between them.
The most distant pair is a-pr
----a---------------------------------------------pr---
║-------------------44,7 MU-------------║
From gene a to vg there are 32.2 MU
----a-----------------------------vg--------------pr---
║-------------------44,7 MU-------------║
║----------32.2 MU------║
Finally, de distance from vg to pr is 12.5 MU
----a-----------------------------vg--------------pr---
║-------------------44,7 MU---------------║
║----------32.2 MU------║--12.5 MU--║
We can name region I to the distance between a-vg, and region II to the distance between vg-pr.
2) To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cM. And that the maximum recombination frequency is always 50%.
1 MU -----------1% of recombination
32.2 MU -----X = 32.2 % of recombination
12.5 MU-------X = 12.5 % of recombination
3) The expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II.
The expected d. recombinant frequency = 32.2% x 12.5% = 0.322 x 0.125
The expected double recombinant frequency = 0.0402 = 4.02%

What is digestion and how does it work
Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Explanation:
Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.
