Cloning is the process that produces a copy of an organism.

How Is It Done?

A biologist, or some type of genetic scientist, takes an egg cell from the organism they wish to clone. They then take the DNA from the cell, and implant it into a surrogate carrier's egg cell to carry it to full term. Once the surrogate carrier has given birth, the clone is produced and the process is finished.

Is Cloning Used Today?

Yes, cloning has been used many times, and is in place today, but a successful clone of a human has not been produced, but clones of other animals has been successfully produced.

Ethical Issues...

There are many ethical issues with cloning, including health risks to the mother, genetic damage to the clone, very low success rate (meaning loss of large numbers of embryos and fetuses), psychological harm to the clone, and the clone not being able to feel for family or loved ones.

Pros & Cons...

Pros: Parents with no eggs and sperm can create children that are genetically related. Same sex couples can have children without the use of donor sperm or donor eggs. The men would only require a surrogate to carry the clone until birth. Parents that have lost a child can have that child returned to them with a clone. Endangered animals can be cloned to save the species (
Cons: Cloning children could foster an understanding that children can be designed and replicated to the parents’ wishes. There would be a lack of uniqueness and violate convictions regarding human individuality and freedom. Clones could be seen as less than human compared with non-clones. Children created by cloning would live in the shadow of the genetic donor, always having to live up to the expectations of a person they were created from. Imagine discovering that you are the clone of a child your parents lost, and you live your life always being compared to the dead child. 95% of animal cloning has ended in failure due to genetic defects, and cloning is considered unsafe because of it. Many believe that cloning is against God’s wishes because the clones would be created by man. Man would be playing God and create people that are unable to feel and empathize. There is also the belief that these clones would be created without a soul (

How is Technology Used in Cloning?

  • Extremely detailed Microscopes

How Is Knowing the Human Genome Helpful?

It is helpful so they can replicate the Human Genome for the cloned organism.

Did You Know?

In the field of genetics and genomics, it aids in sequencing and noting genomes and their known mutations. Also to find similar sequences in DNA between two different species.
  • Microarray: The main principle involving microarrays, is the hybridization of two DNA strands, the property of similar nucleic acid sequences to pair with one another to form hydrogen bonds between similar nucleotide base pairs. Also used to find active and inactive genes in a persons DNA to find mutations.

Is High Tech Genetics Used Today?

  • Bioinformatics: Yes, it is used today, but not often.

Bioethics: Morals and ethics in the scientific field of biology.

How Is It Done?

Genetic scientists figure out what genes the parents want their offspring to have, and they alter the genetic makeup and DNA of the embryo to have those certain genes.

Bioethics: Includes the right and wrong of life principles and they are applied to the scientific studies preformed in biology.

Are Designer Babies & Bioethics Used Today?

Designer Babies are extremely new so hardly anyone has used them, and it is very expensive, so not many people have used it.

Bioethics are used every day in biology and science.

Polymerase Chain Reaction (PCR) & Gel Electrophoresis

Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to molecular size.

How Is It Done?

In gel electrophoresis, the DNA strands that are to be separated are pushed by an electrical field through a gel that contains small pores.

Are Polymerase Chain Reactions (PCR) & Gel Electrophoresis Used Today?

Yes, they are used in criminal investigation cases all the time, and I'm many other scenarios.

Ethical Issues...

The only ethical issues involved with this, would be with the dangers of dealing with electricity, and although the harm it can cause to someone is minimal, it could still be dangerous to deal with.

Pros & Cons...

Pros: The pore size of acrylamide are uniform. It is inert and not react with sample since there is no charge associated with it. Very high resolving power. Can increase or decrease molecular sieving by manipulate the pore sizes. Different buffers can be used to manipulate resolution and run time. Chemically synthethic gel can give more reproducible results. Promote better separations at higher field strengths due to efficient heat dissipation of thin gels (
Cons: Acrylamide and TEMED are neurotoxic compounds. Gloves should be wear when handling solutions of acrylamide and TEMED. Longer wait time for gel to set. More care needed when pouring the gel to ensure gas bubbles are removed (

How is Technology Used in Polymerase Chain Reactions (PCR) & Gel Electrophoresis?

Generally, the gel consist pf acrylamide, bisacrylamide, the optional denaturant (SDS) and a buffer with an adjusted pH, Electricity, stabilizer (such as ammonium per sulfate and TEMED), gel caster, filters, syringes, and many other scientific lab Technology.

Did You Know?

There are two different ways to read the DNA fragments in the gel, one is staining the gel and looking at the DNA fragments that have absorbed the color, and the other way is to look under an ultraviolet lamp (a black light) and they will appear.

Plasmid, Recombinant DNA, & Transgenic Organisms

a genetic structure in a cell that can replicate independently of the chromosomes, typically a small circular DNA strand in the cytoplasm of a bacterium or protozoan. Plasmids are much used in the laboratory manipulation of genes.

How Is It Done?

Researchers can insert DNA fragments or genes into a plasmid vector, creating a so-called recombinant plasmid. This plasmid can be introduced into a bacterium by way of the process called transformation. Then, because bacteria divide rapidly, they can be used as factories to copy DNA fragments in large quantities (
Recombinant DNA is formed by using a restriction enzyme that cuts the double strand at a particular point. The same enzyme is used to cut a second piece of DNA. When the fragments are mixed together, the complementary ends of each strand will bind with those of the other, forming a recombinant DNA molecule (
A transgenic organism carries in all its cells a foreign gene that was inserted by laboratory techniques. Each transgenic organism is produced by introducing cloned genes, composed of deoxyribonucleic acid (DNA) from microbes, animals, or plants, into plant and animal cells (

Is Plasmid, Recombinant DNA, & Transgenic Organisms Used Today?

Yes, they are all used, some are used more often than others, but they are indeed all used today.

Ethical Issues...

  • There are concerns that humans could become resistant to certain fungi.
  • Some spectators believe scientists are starting to act like God?

Pros & Cons...

Pros: Improved Medicines, Improved Livestock (resistance to disease), Improved Crops (resistance to disease, higher yields), Prevention of Genetic Diseases, Lowering the cost of medicines (i.e. Insulin), Safer Medicines (i.e. Insulin), Treatment for pre-existing conditions (i.e. Cancer) (
Cons: Safety concerns (viruses developing antibiotic resistance), Environmental concerns (developing resistance to fungi), Ethical dilemmas over human treatment (i.e. are we playing God?), Potential for Experimental abus (doctors using patients as test subjects), Germline treatment going from treating diseases to a method for picking the traits you want in a child (i.e. specifying hair and eye color) (
