Re: dideoxy chain-termination method for sequencing DNA

I have another question with domwood's answer (I'm not saying that it's wrong - all I'm saying is that I don't get it)... for your answer to 1, to the best of my knowledge, the current mehtod of dideoxy chain-termination method for sequencing DNA does use a fluorescence detector (with a laser) to &q...

Please, can't you tell that this is not homework? And this is not math - how do I "show my work" on something I completely don't understand?????

Re:

Could you please restate where exactly in this question you are having trouble. You're text is very disorganized and hard to read. The best I could do was to give each question their own line. Thanks domwood for replying! However, you were unsure of a couple of points... would anyone like to answer...

What's polygenic inheritance

What does polygenic inheritance mean (the book's (that I use) definition was very confusing - i.e. what's a continuum, etc.)?

Genomic imprinting question

Does genomic imprinting necessarily have to have malignant/have adverse effects - does it imply perniciousness?

Pedigree problem

A question in AP Biology by Deborah T. Goldberg - "A cross was made between two fruit flies, a white-eyed female and a wild mae (red eyed). One hundred F1 offspring were produced. All the males were white eyed and all the females were wild. When these F1 flies were allowed to mate, the F2 flies...

DNA/RNA nucleotides question

I read somewhere that the RNA nucleotides (that are used in transcription) in eukaryotic cells are found in the nucleus. So where are the DNA nucleotides (used for DNA replication) found? And how do they get there (both RNA and DNA nucleotides) - or are they just recycled?

structural formula questions

In structural formulas like -COOH and -CH2OH why is the COOH not written with a subcript of 2 instead of the second O and in CH2OH why is there the subscript 2 instead of writing the two H's out and why isn't it a H3 and why was the last H written out? In structural formulas, why are some subscripts...

lytic cycle question

I was wondering about the lytic cycle: in Biology by Campbell and Reece, 7th edition, on page 338 figure 18.6, it says that the "cell's DNA is hydrolyzed" under "2. entry of phage DNA and degradation of host DNA." My question is why and how is the "cell's DNA is hydrolyzed&q...

dideoxy chain-termination method for sequencing DNA

Three questions on dideoxy Chain-Termination Method for Sequencing DNA: (1) - In DNA sequencing, how come scientists just don't tag regular deoxyribonucleotides with a specific fluorescent molecule (so that each type of nucleotide get a different color - one for A, one for G, one for T, and one for ...

Gene cloning question

1) How do you get the plasmid ( = how do you isolate the bacterial plasmid from cells) out of the cell? If not from cells (although Campbell and Reece Biology says there are on page 387) where do they come from? 2) Some books say that antibiotic resisting genes are already in the plasmid and some ar...
