I need major help in science! (1 Viewer)

[Dimplez]

It's just a few areas I'm stuck on:

*Explain the advantages and disadvantages of DNA replicating exactly
*Explain the advantages and disadvantages of DNA mutating
*Discuss the benefits and problems associated with medical and industrial uses of nuclear energy
*Discuss some benefits and problems of using biotechnology

Help would be much appreciated. Thank you.

*Explain the advantages and disadvantages of DNA replicating exactly
-advantages: prevents from getting cancer cells = cell function normal
- disadvantage: no change in gene pool, provides no variation in organism

*Explain the advantages and disadvantages of DNA mutating
well pretty much change the points for advantages and disadvantages for point 1

*Discuss the benefits and problems associated with medical and industrial uses of nuclear energy
- past paper?umm..... benefits = destroys cancers cells or use of detecting cancer cells e.g cobalt 60
problems = radioactive meds usually have a half life, if medicine is consistently used, patient may be subjected to negative impacts of radiation

*Discuss some benefits and problems of using biotechnology
again past paper.... and benefits is the uses in medicine and agriculture... e.g insulin and BT corn or anti-freeze tomato.... also there is cloning parts of organisms to help humans... e.g creating a heart
problems is the abuse of biotechnolgy including the alteration of an organisms genes such as altering its physical or mental capabilities and having the choice of conceiving a male or female child which is the ethical section of biotech...

hoped that helped even though it was brief...
