Base Sequence of Complementary DNA Strands One strand of a double-helical DNA has the sequence (59)(39). Write the base sequence of the complementary strand. What special type of sequence is contained in this DNA segment? Does the double-stranded DNA have the potential to form any alternative structures?

(3')(5')

Explanation:

The complementary strand is :

(5')(3')

The base sequence of the complimentary strand is:

(3')(5')

Because this sequence is self-complementary, the individual strands can form  hairpin structures. The two strands together may also form a cruciform.

Hairpin structures can be formed by sequences with inverted repeats through two major mechanisms.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
