Explain what is meant by cds in bioinformatics term?

CDS means "coding sequence," i.e. the part of the gene that codes for a protein.

Bioinformatics studies computational algorithms and mathematical models that help identify regions in the genome that are likely to be CDS's.

What are some modern examples of the 27 amendments?

amendment 1. The us declares an offical religan for the nation ( Religan as in Islam, Hinduism, Christanity..)

amendment 2. youre father is arrested for having a hunting rifle in his truck

amendment 4. the police bust into youre home and trash youre place trying to find evidence

these are all true i got them from my social stuides teacher hope this helps! Love you earthlings (; Lol biii

What two types of molecules make up a chromosome and which type holds the genetic information?

Histones and DNA. DNA holds the genetic information. Histones are simply proteins which help organize DNA and compress it. DNA wraps around "bead-like" histones to make "beads on a string"

What is the genetic disorder that causes excessive hair growth?

Hypertrichosis very rare disorder also called werewolf syndrome.

What are the non-genetic causes of microcephaly?

Other possible causes of microcephaly include infections during pregnancy (rubella, cytomegalovirus, toxoplasmosis), adverse effects of medication, and the excessive use of alcohol by the mother during pregnancy

What is doing the right thing?

This one is rather simple or rather difficult depending on what manner one is speaking in. If one tells you to do such a thing then perform thusly: look to the side of your body which is directed eastward while facing north. If you gain sense out of this then your are rather lucky, your search is complete and no more need be said. If not then read what follows. The "right thing" may be interpreted in various ways. One may see it as the "just thing", the "proper thing", the "ethical thing", the "aesthetic thing", the "holy thing", perhaps even the "unholy thing" and many many more. I cannot pretend to be so concrete as to chose which one is best, as one touches upon an answer it crumbles to your feet. Many philosophers have touched upon this issue. It was (according to some interpretations) the main focus of Kierkegaard's Either/Or. He concieved, in the first volume, (paraphrasing) that either you will or you won't, you shall regret both. The second volume was a bit more opptimistic: perhaps you will regret both, but is the fact that you made a decision that you may learn from that counts. Nietzsche would probably assure you that you will do the right thing if you believe that you are doing such. On this is must say that it is a very subjective thing and that in doing what is "right" you are the final judge (unless you are a theologian in which you are the final judge of whether or not your God(s) believe you did the right thing...). -QEM

Should insurance companies be allowed to discriminate according to genetic testing?

If I have GOOD genes, and am not likely to end up with cancer, heart disease or other expensive types of medical conditions, why should I be required to pay the same rate for insurance as those who have a high likleyhood of getting such diseases?

Insurance is about probability and risk. Insurance companies pool a bunch of people together, determine the risk of a particular disease and calculate how much it will cost, then decide how much to add to the price of insurance to cover people for the disease. They are covering their risk.

It's the same with auto insurance. Mature, careful drivers are not charged as much for insurance as are immature or careless drivers. People who have been arrested for drunk driving are considered to be very high risk drivers and as such their insurance rates are very expensive. Do you think that careful drivers should pay as much as careless drivers? Careful drivers don't think so, just as people with healthy ancestors don't generally think that lower medical and life insurance rates are a bad idea if we aren't likely to get a disease.

When to use a fvb mice?

FVB mice are often used in production of transgenic mice due to their excellent reproductive capabilities and nurturing characteristics. In addition, FVB mice have large embryos which makes them easier to manipulate for microinjection of transgenes.

Why are micro measurements necessary when working with DNA?

Micro measurements are nessessery because DNA is so small and microscopic and other measurements are simply too large (they are bigger than the DNA).

What are benefits of genetic modification?

Genetic modification can be used beneficially in a multitude of ways,

Farming:

GM crops can be made to survive in conditions where they normally wouldn't grow, They can be made more juicy and more numerous so the farmer can make a better living, they an be less likely to succumb to diseases.

Bacterial:

Bacteria can now be modified in such a way as to produce useful molecules like insulin.

Human:

Human genetic modification is entirely theoretical as no method of genetic manipulation is currently seen as moral.

However it is possible that genetic modification could make future generations immune to diseases we fall pray to, Make them stronger, faster, smarter and more healthy than we are.

Techniques of denormalization and its advantages and disadvanteges?

When you design a database, you first want to normalize it. Main purpose is to avoid data duplication, because duplicate data takes up unnecessary space and is harder to maintain.

Suppose you want to store information about your customers. You want to store their address to send them promotional material. You also want to store what products they bought so far. If you'd put that in one table, you'd be repeating the customer's address for each article they bought. When one of them changes address, you need to remember to change all the records to update the address to avoid data inconsistency.

So you normalize this bit, and create a table with e.g. customer number + customer name + customer street + customer zip code/postal code, a second table with zip code + city, a third table with customer number + product number, a fourth table with product number + product description + vendor number, etc.

Now look at the I/O involved in getting at that data. When you put all the data in one table, accessing all the data will normally involve fewer I/O transactions and therefore be faster than accessing the data spread over multiple tables, which requires jumping back and forth from indexes to data records, as it . And despite the fact that I/O performance has improved tremendously since early days, it still is the slowest component in a computer.

Computers with slow I/O subsystems may also benefit from denormalisation. Denormalisation basically is the process of finding the balance between avoiding data duplication and ensuring database performance.

What is wet cell weight?

The mass of a cell which has not been dehydrated.

Is there a real humanzee?

To tell you the truth I'm not sure if there is a Humanzee but it has been claimed it was made once in china and one in america, But there is no fact.

How do you calculate Mean Generation Time?

g=(log Nt- log Nto)/log 2 where N=absorbance reading @ time indicated

MGT= (t-to)/g

Who developed the first DNA identification system?

The Max speed would be about 5 5 since that iis the speed limit.

What causes translation to stop?

The end of translation occurs when the ribosome reaches one or more STOP codons (UAA, UAG, UGA) on the mRNA.

At the ribosomal level, there is a competition between tRNAs and release factors. When a stop codon is reached, a release factor inserts into the A-pocket of the ribosome (keep in mind that a tRNA molecule cannot recognize a stop codon). Once the release factor is recognized by the ribosome, the polypeptide chain is signaled to release.

Why is there a reddish liquid seeping out of your leg after you accidentally scraped it on the ground?

It's called blood because the scrape was deep enough to cut your vein and have the precious blood come out

What is the genetic material always found in the nucleus?

Genes in the nucleus are composed of deoxyribonucleic acid, in the form of a double helix.

DNA = Deoxyribonucleic Acid

Why does genetic code have to be exact in a protein?

An exact protein is produced only if all the amino acids (the building blocks) are in the correct sequence. Even is one amino acid is not in the right sequence (or even missing) the protein would not be able to correctly function. It may not be able to function at all.

Since the genetic code is responsible for the creation of a protein, this has to be absolutely accurate in order to create functional proteins
