I really need to make sure this is correct for tommorow please help!
The significance of specific base pairing in DNA is that
A) it stabilizes the sugar molecule
B) it provides a method for making exact copies of DNA
C) it prevents errors in DNA replication
D)protein copies can be be made directly from the DNA
I'm pretty sure the answer is D, am I correct?
the answer is C. because the pairs are unique to each other [a-->T, G-->C] then they are unable to form incorrectly. they still replicate incorrectly, of course, but not nearly as much error occurs
Yeh that's what I thought too but apparently I got it wrong on my homework. The class is online and we can make corrections but I thought it was right to begin with so now I'm confused
huh.
well, i doubt it is D. it is not necessarily because of the pairing that protein copies are made.
A could be referring to the 5 carbon sugar forming the helix of the DNA, but again i fail to see why the pairing itself has an affect on it.
i would argue that B is correct because like i said above a-->t only so using half the DNA strand and attaching a pair would provide a concrete method. it would be like so: 0-->1, 1-->0
0100110
1011001
you could use one line or the other to pair it with a matching value and end up with the same pair, if that makes sense.
Alright well thanks a lot i guess I'll just have to check with my teacher for sure.
What was the correct answer?
To determine the correct answer, let's examine each option:
A) "It stabilizes the sugar molecule": This option does not accurately describe the significance of specific base pairing in DNA. While specific base pairing does contribute to the overall stability of the DNA molecule, it is not its primary significance.
B) "It provides a method for making exact copies of DNA": This option is partially correct. Specific base pairing is indeed crucial for DNA replication, as each DNA strand acts as a template for the synthesis of a complementary strand during replication. This process allows for the accurate duplication of the DNA molecule.
C) "It prevents errors in DNA replication": This option is also partially correct. Specific base pairing plays a role in helping to prevent errors during DNA replication. This is because each specific nitrogenous base pair (adenine-thymine or guanine-cytosine) has a complementary structure, which allows for accurate base pairing during replication and reduces the likelihood of replication errors.
D) "Protein copies can be made directly from the DNA": This option does not accurately describe the significance of specific base pairing in DNA. Protein synthesis is a separate process that involves the transcription of DNA into RNA and the translation of RNA into proteins. While DNA is involved in the production of proteins, it is not a direct consequence of specific base pairing.
Based on the analysis above, the correct answer is B) "It provides a method for making exact copies of DNA," as specific base pairing allows for accurate DNA replication.
