Heredity B/Designer Genes C Question Marathon

[SWAnG]

Is this a trick question? Technically it could be any of four genotypes, and any of four phenotypes. But it is all perchance. We don't know for sure what the genotypes and phenotypes are of the children.

Well, not exactly. (Click to Show Hidden Text)

There could be any of 4 different genotypes, and 3 different phenotypes. It's fairly evident that vennowsah is correct, so I believe he can ask a question anytime unless the person who asked the question comes on. But we don't need to debate small technicalities.

Alright, here are my questions:

1) Three models of DNA replication were proposed after the discovery of the Double Helix by Watson and Crick. What were the three models? Which of these models proved to be the way in which DNA replicates? Explain this type of replication.
2) What is the difference between introns and exons?

[SWAnG]

1)Conservative, Dispersive, semi-conservative. Semi-conservative, where replication results in one original strand, and one new strand.
2) introns are not expressed, exons are expressed in DNA after splicing

This is late, but vennowsah, yes, you are correct. I was looking for your second answer more than the first! Parents: AO AND AB. Kids: AA, AO, AB, and BO.

That is correct! You may ask now.

Ah, that's nice to know. Thanks!

What is the process undergone for pharming?

Im not sure dont know very much about this one. (Click to Show Hidden Text)

Genetic engineering??

[vennowsah]

I think.. (Click to Show Hidden Text)

Isn't pharming the process of creating a genetically modified organisms by inserting a certain gene into the body of a host organism? Such as injecting a new piece of DNA into a fertilized egg so that a transgenic organism will be produced.
