Who came up with the idea of genetic engineering?

Genetic Engineering, the technique of DNA cloning was perfected by Stanley Cohen and Herbert Boyer in 1973.

Genetic engineering cannot be perfected. It likely never will be. It is an evolving science, roughly 20-30 old (when you consider the complexity of the subject).

Is it possible to create genes that function to make the body younger?

There is speculation that the ability to slow aging may occur using the CRISPR/Cas9. But use of this in humans may have ethical issues.

What is demineralization of the bones?

Demineralization of the bones is when the bones have a lowered amount of minerals in the bone. Phosphate and Calcium is lowered in the bone and causes the person to have reduced bone strength.

Why does meiosis result in more genetic variation than mitosis?

It would be wrong to consider mitosis insignificant as it helps in cell repair and replacement in our daily life and it would be impossible to survive without it and asexual reproduction as well but if it weren't for meiosis, none of us would have been born :) Meiosis is responsible for the division for our gamete cells which leads to the formation a zygote. from there on mitosis takes over.

Where is genetic information stored and copied?

the nucleus stores all the genetic information (DNA)

Is laughter genetic?

Laughter is not genetic.Even though that people have same DNA,they cannot get laughter as a heriditary characteristics.WE cannot consider laughter as a heriditary characteristic cause theres no hormone for laughter.

Can a person be cloned?

As of today, scientists have not cloned any people. They have only cloned animals and are still trying to find the symptoms of cloning. If it is harmless, scientists may start cloning people. If it is harmful, you will not might hear about clones in this world....

What is chemical genetic engineering?

Taking a piece of DNA from one organism and putting it into another organism.

How is genetic engineering used to improve livestock?

injecting growth hormones, genetically engineered in bacteria, it goes into dairy cows, it also increases their milk production.

What part of a DNA molecule is responsible for the genetic code?

The genes present in a DNA molecule are responsible for the genetic code. Within the genes, the exons specifically are the coding regions.

What kind of alleles does a heterozygous individual have?

2, it means that both of the alleles are different when compared to homozygous. Homozygous alleles are like aa or AA. Heterozygous simply means Aa so it has one dominant and one recessive allele

Are dimples from a mutation on the chromosomes?

dimples are a "birth defect" means that your muscles are too short thus pulling the skin causing this little holes, why do you think most babies have them? cause their muscles developed and they have a lot of baby fat same goes to people with a little extra fat

Why are hooke and leeuwenhoek so important to cell study?

Anton van Leeuwenhoek was important because he invented de microscopy and thats the way scientists discovered bacterias and labeled the elements of a microscopic cell. His researches in science where also really important.

How many people use genetic testing?

30% of people or doctors use genetic testing because of the change in chromosomes

What causes one flower to grow bigger than the other?

The amount of sunlight, water, and nutrients from the soil one plant receives definitely affect how large the plant grows, but genetics is key. With no viable seed, and environmental factors do not matter.

What are the products of biotechnology?

The scope of biotechnology is diverse. It includes the use of microorganisms, such as bacteria or yeasts, or biological substances, such as enzymes, to perform specific industrial or manufacturing processes. Applications include the production of certain drugs, synthetic hormones, and bulk foodstuffs as well as the bio-conversion of organic waste and the use of genetically altered bacteria in the cleanup of oil spills.

What are the Statistics about cloning on humans?

Some interesting facts about cloning are: Human stem cells and rat cells have been mixed at some point. The first cloned animal was a tadpole. Despite the research that has been put into cloning, 95% of attempts fail.

The process of what produces a new copy of an organism's genetic information?

The process that makes a new copy of an organism's genetic information and then passes it on to new cells is called mitosis.

Which of the following is correct about eukaryotic cells?

they have a nucleus, they have a cell membrane, they are not found in plants.

How can a small change in a persons DNA cause a genetic disorder?

Some genes encode products that regulate the translation of other genes, or the activity of other proteins, so one small change will affect a lot of other genes/proteins. If that change affects something critical it might lead to a genetic disorder.
