List advantages and disadvantages of cloning?

Answer 1

Advantage In 2008, Professor Eiberg from the Department of Cellular and Molecular Biology stated, "Originally, we all had brown eyes but a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a 'switch,' which literally 'turned off' the ability to produce brown eyes." He explains that things like "hair color, baldness, freckles, and beauty spots" are all brought about by mutations.
Disadvantage As much as mutations have helped humans, mutations are also the cause of certain diseases. For instance, E! Science News 2008 explains how a particular mutation relatively common on the Indian subcontinent predisposes people to Heart disease. Many other diseases, such as cancer, Diabetes and asthma, are linked to genetic mutations.

Answer 2

DNA replication allows the cells to behave correctly so that mutations such as cancers do not spread throughout the body. The disadvantage of replication is that a lot of storage is needed to keep DNA information for replication.

Answer 3

- Semiconservative: means you get mostly faithful replication, so that mutations (insertions, deletions, substitutions of bases) are avoided. So, all the cells in a single organism should be identical in terms of genetics. That helps prevent autoimmune attacks.

- Effective proofreading mechanisms: even if the incorrect base is initially incorporate, the DNA polymerase has a conformation such that any mismatched pair won't easily pass through it. That makes the newly-formed double helix back up and be re-processed so that the correct base is inserted.

- Allows for some mutation, which is the ultimate source of variation: the proofreading mechanisms aren't 100% accurate, so some bases can change. Most of the time, these mutations are either deleterious or neutral (no impact). However, every once in a while, a mutation can lead to a new phenotype, which then can be acted upon my natural selection.

Answer 4

ADVANTAGES

Helps infertile couples

Can be used to protect endangered species

Improves food supply (meat)

Can reverse the aging process for humans

Used to replace dead people

Can be used to replace damaged organs

DISADVANTAGES

Many births of deformed children

Inheriting diseases

Can devastate parents if unsuccessful

Clone may be teased/bullied about who they really are

Change peoples thoughts on 'God' and religion

Cannot always trust Science Technology

Clone may not live very long

Selling and buying clones is another threat to humanity

Clone would get treated like and object and not a human

Answer 5

If DNA does not exactly replicate, the next cell will not behave correctly. This causes mutation - cancer, for example.

Answer 6

Advantages over what? As far as we know, every organism has DNA and only DNA - there are no other options.
