You can tell the vein from the others by holding the leaf up to a light. This makes the leaf a bit see through and the veins will be clearly visible as they do not become semi-transperent. You can also put paper on top of the leaf and rub gently over the paper with crayon to see the veins. They will make darker or lighter lines on the paper depending on if you have the leaf facing up or down.

Answer:
T-A-C-T-G
Explanation:
Deoxyribonucleic acid, widely known as DNA, is the genetic material in living cells. It is a double-stranded molecule, with each strand arising from the pair of nucleotide monomers that forms its structure. In the DNA, four nucleotides exist namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
These four bases occur in different combinations to form a sequence that makes up each strand of the DNA. However, each nucleotide pairs with one another using the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine will always hydrogen bond with Thymine, while Guanine will always hydrogen bond with Cytosine i.e. A-T, G-C.
Based on the above, a DNA strand with sequence: A-T-G-A-C will pair with another DNA strand with sequence: T-A-C-T-G.
