If one strand of a segment of double-stranded DNA is tandemly repeating, the complementary strand will consist of
interspersed repeats, tandem repeats, same sequence in reverse order, or not enough info to decide?
anyone have any ideas, tips?
it is ...
a|T
C|G
To determine the complementary strand of a tandemly repeating segment of double-stranded DNA, you need to understand the base pairing rules in DNA. The four nucleotide bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).
The base pairing rule states that adenine always pairs with thymine (A-T) and cytosine always pairs with guanine (C-G) in a complementary manner.
In your given sequence, the complementary base pairs for each nucleotide are as follows:
A pairs with T
T pairs with A
C pairs with G
G pairs with C
Based on this information, we can derive the complementary strand. The given sequence is:
Original strand:
a - T
C - G
Complementary strand:
T - a
G - C
Therefore, the complementary strand consists of the following sequence: T-a-G-C.
To answer the question, the complementary strand does not contain tandem repeats or interspersed repeats. It is not the same sequence in reverse order either.
