The matching strand to the one in Figure 12-7, reading from the bottom up, would be???

the figure is (from the bottom up) T C G A

please help im so lost. :(

AGCT.

To find the matching strand to the given strand (T C G A), we need to determine the complementary nucleotides for each base.

In DNA, the complementary base pairing rules are as follows:
- Adenine (A) always pairs with Thymine (T)
- Thymine (T) always pairs with Adenine (A)
- Cytosine (C) always pairs with Guanine (G)
- Guanine (G) always pairs with Cytosine (C)

Since the given strand includes the bases T, C, G, and A, we can identify their complementary bases as follows:
- The complementary base for T is A
- The complementary base for C is G
- The complementary base for G is C
- The complementary base for A is T

By applying these complementary base pairing rules, we can determine the matching strand:

Given Strand:
T C G A

Matching Strand (reading from the bottom up):
A G C T

So, the matching strand to the one in Figure 12-7 (reading from the bottom up) would be A G C T.

I think its TCGA...

i wish i could help sorrie

thanks anyways :)
