Genetic Engineering

Questions about the manipulation of an organisms genes in order to alter the morphological or chemical traits of the organism.

Why Bacterial DNA is used frequently in genetic engineering?

Bacterial genomes are relatively small and some (eg. E. coli) are very well characterised. Also, most bacteria have a very short generation time so any DNA that is inserted can be multiplied quickly.

What organelles read codes genetic measages?

Ribosomes are the organelles that read coded genetic messages. Ribosomes can be found in all living cells.

Are there any disadvantages from genetic engineering?

  • genetic engineering can increase genetic diversity of species of populations, esp. those that inhabit. (domesticated animals)
  • increase efficiency of ecosystem services by other organisms:
EX.

MODIFICATION OF TREES' GENES CAN INCREASE ROOT SYSTEMS OF ORGANISMS AND REDUCE DAMAGE BY FLOOD PHENOMENON THROUGH FLOOD MITIGATION.

  • modification of DNA structure of agricultural crops can increase growth rates & resistance to different diseases caused by pathogens and parasites, and can increase production of food sources to host the world's growing populations and reduce the usage of chemicals like fertilizers and pesticides, which can decrease the risk of inbreeding which can produce infertile youths.

BASICLY, I THINK GENETIC ENGINEERING IS QUITE BENEFICIAL! :) GUESS WHO I AM! :)

AnswerIf you are looking for a good answer, look for a scientist who works with it. DO NOT look through websites. people have misleading information saying anti-genetic engineering things that contradict everything that is the truth. I am fully pro-genetic engineering and I know my stuff. People who make hate-sites do not have a clue so be careful.

How do mutation and crossing over cause genetic variation?

In meiosis I, segregation of chromosomes...that is, separating off into pairs, allows for crossing over to occur. Crossing over is one mechanism responsible for gene recombination to occur, and genetic recombination is one way that variations in traits increase.

Why cant two siblings have the same exact traits?

The premise of the question is flawed. Unless they are identical twins, siblings DO NOT receive the same genetic material from their parents. Normally, children receive 50% of the genes of each parent to create a new 100% combination. So you and your sibling have both inherited 50% of your father's DNA, for example, but you didn't get the same identical 50% as your sibling unless you're identical twins.

Is baldness genetic?

Natural hair loss is known as androgenetic alopecia and, according to the American Academy of Dermatology, is the most common cause of baldness. The gene can be inherited from either your mother's or father's side of the family, though you're more likely to have it if both of your parents had hair loss. There are also good hair supplements out there like Reloxe that could help people with hair loss problem. You can learn more of it here: http://www.reloxe.com

Is it legal to clone humans?

There are no federal laws completely banning human cloning in the United States. There are regulations against using federal funds for cloning research.

A United Nations declaration was adopted, calling for the worldwide ban of human cloning.

What causes genetic disorders are permanent changes in the DNA sequence?

Bike riding drunk. You will fall and and hit your head on the same rock your bike hit. This did happen to my uncle.

How do you change the genes of a child?

Exposure to mutagens, such as chemicals, radiation ect. May I ask why you would want to do this?

How can genetic counselors predict genetic disorders?

Well certain disorders are found on certain chromosomes and on certain parts of the chromosome. How they find out how, i don't know. But if some pieces of a specific chromosome they can predict they will have a certain disorder

Is it possible to clone a human?

Yes. It can be done in the same way as did in sheeps,cow etc. But human cloning is legally banned in many countries.

What causes webbed fingers?

Doctors call this condition syndactyly. Webbed fingers or toes can be part of Turner's Syndrome, which is a chromosomal disorder that affects only females. It involves the absence of all or part of one of the sex chromosomes. Normal female chromosomes are expressed as XX. In Turner's Syndrome, the sex chromosomes are expressed as XO, to indicate that there is a chromosome missing. More commonly though, syndactyly is caused by a genetic defect, and is therefore found to run in families. It is found in both males and females who have the normal arrangement of sex chromosomes: XX for females; XY for males. There are five different types of syndactyly which are classified according to which fingers or toes are involved. This condition can be corrected by surgery, which often involves a small skin graft from another part of the body. With the milder types of syndactyly, surgery can be considered elective (that is, not strictly necessary.) However, when fusion of the fingers or toes is extensive, or when the fusion will cause deformity as the fingers and hands grow, surgery is necessary.

Why is engineering tolerance important?

Because you can count on parts to not be perfect. So if you want them all to fit, the need some room for the grease.

Describe three ways genetic diseases are caused?

1. (1) Produced by an abnormality in, or a mutation of the genetic code in a single gene; (2) Caused by several abnormal genes (Producing so-called polygenic diseases); or (3) Caused by the abnormal presence or absence of an entire chromosome or by alteration in the structure of chromosomes.

What kind of disorder is diabetes type 2?

Diabetes type 2 is a metabolic disorder, caused by insulin resistance in the cells of the body, combined with insufficient insulin formation. It is quite a separate disorder than diabetes type 1, which is caused by an autoimmune reaction that destroys the insulin-producing cells in the pancreas.

What is the genetic composition of an organism?

A genome of an organism is described by all of the organism's hereditary information. Anthing that the organism gets from strictly hereditary sources are considered the genome type of the organism.

Contrast the location of genetic material in bacterial cells to its location in plant and animal cells?

1. The nucleus in animal and plant cells contains the chromosomes. In bacteria, the single circular chromosome is in the cytoplasm.

2. The DNA in plant and animal cells is double stranded; in bacteria it is mostly single stranded.

Why are pedigree helpful in determining genetic disorders?

The genetic counselor can use a pedigree to see which previous generations had inherited disorders or were carriers of inherited disorders. This can be used to determine whether the parent is a carrier of an inherited disorder or completely free of it, (unless the parent clearly has the disorder), which can be used to determine the chance of the inherited disorder being passed onto the children.

Why is cloning considered asexual?

Sexual reproduction requires DNA from two members of the same species to create new life. One male and one female. Cloning only requires DNA from only one source to create new life. Asexual reproduction (in nature) also produces new life with DNA from only one source.

What mutagens may produce genetic disorders?

nicotine in tobacco from cigarettes... can make cells mutate which is cancer
