Answer:
UUAACG
Explanation:
The complementary strand of the DNA strand AATTGC would be UUAACG.
The complementary nucleotide for Guanine [G] will be Cytosine [C] and applies to both DNA and RNA. But the complementary nucleotide for Adenine [A] will be Thymine [T] in DNA and Uracil [U] in RNA.
A codon is a triplet of nucleotides, so it could be any three nucleotides in the strand. Example: AAT, ATT, TTG or TGC.
i think A would be right if they are taking ab the scientific method
CFCs are Chlorofluorocarbon substances used in refrigerants (subtances used to keep other things cold) and in aerosol products.
they are both relatively nontoxic(nonpoisonous) and nonflammabale - at least as compared to alternatives.
They are rather volatile - they are not very stable. Therefore it does not make sense to say that they are strong - the correct answer is then strength.
That would be beneficial to them because they wouldn't lose as many trees to disease or insects, so they are able to sell more.
That's what I got from it at least.
