Question

Scientists utilize various methods in order to manipulate DNA. What is involved in genetic engineering?
a.
reading a DNA sequence.
b.
editing a DNA sequence.
c.
reinserting DNA into living organisms.
d.
all of the above

Answer 1

all would be the best bet

Answer 2

Genetic engineering is the manipulation of genes. So, I'd say (b) editing a DNA sequence because the question is about what methods are involved in MANIPULATING DNA and not the steps involved in genetic engineering.

Answer 3

reinserting also

Answer 4

it is what we call the recombinant dna

Answer 5

without reading the sequence, genetic engineering wouldn't be possible

Answer 6

so you read, you manipulate and or you reinsert

Answer 7

does it make sense?

Answer 8

I agree @nincompoop but the question is about the manipulation of the DNA and not the steps involved in genetic engineering. I think that it's a targeted question.

Answer 9

it doesn't have to be steps. you can't manipulate without reading and you can't manipulate without reinserting either. recombinant dna is the hallmark of genetic engineering

Answer 10

if steps are in question it would be more complicated than the three options provided.

Answer 11

you can trust @Kayne 's answer though.

Answer 12

I agree @nincompoop .. But I think even if it would be more complicated, it would more or less be summed up in those three options. But you know @nincompoop .. what's bugging me is that part which says "manipulation of the DNA".. that's why I think that it's a targeted question which implies that you should overlook the other options and focus on just how to manipulate the DNA sequence itself. :s

Answer 13

its d

Answer 14

thanks guys
