Answer: double helix
Explanation: The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
i think it would be true but not 100% sure
Answer:
The correct answer is- TAAGCCGATAAATGCTAACGGTA.
Explanation:
DNA is a nucleic acid molecule made of two strands. Each strand is made up of nucleotide bonded via phosphodiester bonds. Each nucleotide is made up of- 5C deoxyribose sugar, a phosphate group and nitrogenous bases.
DNA replication produces an exact copy of the DNA molecule through complementary base pairing. The complementary strand is formed by adding nucleotide through DNA polymerase which adds base pairs according to the Chargaff rule. The Chargaff rule states that A will bind T via two hydrogen bonds and G will bind C via three hydrogen bonds.
Therefore, the complementary strand will be-TAAGCCGATAAATGCTAACGGTA
Explanation:
option B is the correct one as it is done by nitrogen fixing bacteria.
