Which of the following is not a reason for the wide use of CFC's during the 1920's - 1990's?
Mila [183]
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.

How do you find the sequence of bases on a DNA strand?
gizmo_the_mogwai [7]

Answer:

First of all, make sure that you indicate on the question itself the directionality of the sequence: which makes this (by convention) 5′ AGCTCAG 3′. We assume that any sequence written without the 5′ and 3′ designations is from the sense strand, and reads from 5′ on the left to 3′ on the right. Therefore, the complementary sequence, which is being asked for, must go from 3′ to 5′ as matched up (because it runs in the opposite direction). So, this is 3′ TCGAGTC 5′. It is true that we often write sequences without the formal directionality indicators, and if so, we do it from 5′ to 3′. However, if you put “CTGAGCT” as your answer, experience tells me that you have a very good chance of getting it marked wrong (unless your instructor is testing you all with a little tricky questioning).

Explanation:

Hope this helps
