Answer: Polygenic recessive
Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.
Is this really biology, are you sure?
The boiling point of AB will be high as it is polar and thus intermolecular bonding thus increasing the bp of the compound !!
so the answer is first one !!
Ok, DNA Polymerase is an enzyme that joins free nucleotides to both existing strands of DNA, which means it isn't D (which is helicase, by the way). They normally work in pairs of two for this function, so it isn't C; this is because if it created a fork, there would only be one needed. Now, concerning A & B, you'll have to be careful. Depending on how A is worded contextually, it could be correct, or it could not. I'm not sure I like the wording "chunks." Which is why I think it's B. Polymerase joins one strand of the "unzipped" DNA to free nucleotides that match it, and these aren't "chunks of DNA." Now, Polymerase is VERY accurate, only making a mistake once every millionth (or billionth?) nucleotide matchup. When it does make a mistake (most of the time), it'll go back and fix it. So I believe the best answer is B, it checks for errors.
Hope this helps!
