because the behr cannot respond quick
Edited answer:
During hybridization additive gene action from the two parents result in heterosis which ultimately increases food production in crop plants.
because you need the phosphate of the foreign DNA fragment for ligation. If not inactivated before you add the fragment, SAP will imediately remove the phosphate form your fregment too leaving you with two dephosphorylated fragments that are not easy to ligate..
Why is cloning a form of asexual reproduction?
Sexual reproduction requires the mixture of DNAs from two different sources(i.e. you got a set of chromosomes from you mother and one from your father). Asexual reproduction involves a copying of just one source of DNA. In cloning, you take DNA from just one source and so it is asexual.
DNA cloning is the production of large number of identical DNA molecules from a single ancestral DNA molecule. It is of two types
1. cell based DNA cloning
2. cell free DNA cloning
What does the cell nucleus look like under medium power objective of the microscope?
When looking at aÊmedium power microscope, the cell nucleus looks like a black spot or a darker oval in the cell. Using a high power will let you see a little more detail such as areas of light and dark chromatin.

Are daffodils transgenic plants?
At this time (December 2013), there is no indication that daffodils are transgenic plants.
Difference between vertical and horizontal gel electrophoresis?
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
What is the difference between an amino acid and RNA?
RNA is a polymer of ribonucleic acids. Amino acids are the monomers of proteins.
How do genetic variation and environmental factors work together to cause natural selection?
Organisms (plants, animals, bacteria, etc) that have more traits that are favorable in the environment will live longer and have more opportunities to reproduce and create offspring that share their favorable traits. Organisms with traits unsuitable for the environment will die sooner, and will produce fewer or no offspring. If given enough time in a stable environment, the population will eventually reflect the genes best suited for it, assuming pure natural selection.
How do you describe how DNA copies itself?
DNA replication occurrs through a process called mitosis. The stages of mitosis are (I)PMAT.
In the G1 phase, protein synthesis occurrs and mRNA runs along the chromosomes. In the S phase, DNA polymerase runs along the chromosomes/chromatids and creates complementary strands of DNA. In the G2 phase, the 23 chromosomes all have sister chromatids.
2. Prophase- Chromosomes condense, spindle fibers form, and the nuclear membrane disintegrates. (23 chromosomes/46 chromatids)
3. Metaphase- the chromosomes line up in the middle of the cell and spindle fibers from the centrioles connect to the chromosomes at the kinetochores. (23 chromosomes/46 chromatids)
4. Anaphase- Sister chromatids are pulled apart by the spindle fibers to each pole of the cell. (23 chromosomes/46 chromatids)
5. Telophase- nuclear envolopes form around the chromatids at each pole, the spindle fibers reduce, the chromatids decondense. (46 chromosomes/ 46 chromatids)
Then cytokinesis occurrs to split up the cell into two cells.

What is scotopic sensitivity disorder and how is it treated?
This website should clear up any questions you have about the disorder: http://www.readingandwriting.ab.ca/judypool/irlen.htm If not, you can just google scotopic sensitivity disorder, and you should find thousands of sites describing it. Hopefully this helps, if it doesn't, then I'll be happy to answer any other questions you may have.
Is it possible to reappear for MHTCET once admitted to engineering?
I'm not an authorized personnel from the Department of Education
for the State of Maharastra :) But it should be possible to do that.
If its just to change the college allotment, then I think its bit of a waste.
However, the institutional resources and peer group calibre would affect
you in a positive way ... if you are up to taking and looking out for
challenges :) So, if you feel you can do better a second time, just go for it.
I don't think anybody would care to ask you about your first attempt or it
is necessary for you to mention it later as well.
But there's ton's of good books and material that you could help yourself
with, and there's internet as well. So you can stick to your current
institution as well.
If you are interested in changing your stream to Medicine or something
different altogether then there's no stopping you.
Presuming that you have been admitted to an engineering insitution,
I hope you haven't parted with a significant donation to the institution.
If so, you should really think about doing anything drastic. Although, just
reappearing for another MHT-CET wouldn't hurt you.
So, hopefully you'd just have to incur the additional expenses for the
MHT-CET exam fees apart from your annual engineering college admission
fees.
Hope this helps.
Can a roan bull and a roan cow have a red and white cattle?
A roan bull and a roan cow can indeed breed to have red and white cattle. This is due to alleles mixing.
How do you increase stamina in short time?
Methamphetamine, first used, I believe, on a large scale, in WW1, issued to troops on a routine basis. Other stimulants, such as coca leaves chewed with lime or other alkaline (hence the song), have been used for similar purpose, notably in the Andes, from antiquity to present.---Rick
How do mass extinctions appear to be related to the appearance of new major groups of organisms?
I was thinking the same thing. i think that its because when one group goes extinct the new major group thrives because somehow the now extinct group died off.
What is one major surgery Vincent had correct in gattaca?
One was a surgery to increase his height they lengthened the bones in his legs by 2 inches.
Should cloning be used to create the perfect human?
Hi! Human cloning can probably be perfected but scientists are not that advanced yet. I'm working on an essay for human and animal cloning. Animal cloning has been successful with Dolly the Sheep and others but most of them have died young. Others also say that cloning has hidden DNA damage. So animal cloning is close to perfection-really close they have been successful but humans don't want to risk being tested unless scientists are absolutely sure. We have a while to wait!
How can you relate the full metal alchemist in biology?
The creation of Chimera can be related to biology in the sense that producing a Chimera involves manipulation of the DNA by the introduction of different genes within the DNA and RNA sequence .
What is the purpose of prepregnancy counseling?
To help patients have full-term, healthy pregnancies and babies. The education helps because lifestyle habits such as smoking or alcohol usage can be hazardous to a developing fetus.
