What are short tandem repeats?
A short tandem repeat or STR is a type of polymorphism, where short sequences of DNA are repeated. It is a useful tool in forensics because the number of times a DNA sequence is repeated for a given STR varies between individuals.
What takes advantage of repeated DNA sequences that do not code for proteins?
DNA fingerprinting is a technique that takes advantage of repeated DNA sequences that do not code for proteins. It is a useful technique in forensic science.
Suggestions useful for fingerprinting DNA?
A DNA fingerprint is 'taken' by removing the genetic material from a cell. This genetic material consists of DNA bases which are sorted into groups. The DNA bases are then cut and some radioactive nucleutides added. The radioactive DNA is then collected and is ready for analysis.
When is it useful to draw a genetic cross diagram?
When estimating the percentage chance the offospring has of having a particular inherited characteristic eg brown hair
What is selective breeding?
Selective breeding is the process in which two animals from the same species reproduce due to useful characteristics. Two animals with a certain type of characteristic are bred together to produce offspring. Then the offspring with the most useful characteristic breeds with another offspring to produce more offspring. This process continues for generations until the offspring consistently have the useful characteristic farmers or scientists are looking for. Cross-breeding is a type of selective breeding except with animals from two organisms from the same species but not the same breed. Selective breeding is one of the most common causes for a wide range of breeds in animals and varieties in plants. this is incorrectIt is the process which humans use animal breeding and plant breeding to selectively develop particular characteristics by choosing which typically animal or plant males and females will sexually reproduce and have offspring together

Which genetic engineering branch is most useful for the goal of supplying evidence in court?
Genetic FingerPrinting
Why do humans feel it is necessary to pursue fingerprinting?
DNA fingerprinting offers a technique to single out an individual with a 100% success rate. A persons DNA fingerprint is unique and this quality becomes very useful in forensic applications. Therefore, there is much interest in DNA fingerprinting. In research however, fingerprinting is used to differentiate between different strains of a certain species of bacteria for epidemiological studies

Why is fingerprinting useful?
it shows you evidence it help police to catch or keep trace of bad people like robbers , thief , pickpocket and kidnaper.
What is the name of a bycycle which can be ridden by more than one person?
For two people it's a tandem. For more people you're looking at some sort of custom build, and they tend to: a) use motorcycle wheels in order to be strong enough. b) not be particularly useful in practice.
What is a characteristic of electromagnets that makes them useful in simple tools?
they are magnetic
What makes characteristic properties useful to scientists?
Well, they characterize, dont they?
What constant properties that are most useful in identifying a substance?
Characteristic properties.
Name 2 ways DNA fingerprinting is not useful?
If they are partial prints. If the prints belong to someone that has already been excluded, i.e., investigators or persons who are innocent.
