. Diameter of DNA double helix is uniform through out the structure and it is 2 nm. Multiple Choice Complementary base pairing across the double helix allows information to be transferred via DNA replication. This preview shows page 6 - 8 out of 10 pages.

The double helix twists in a left-handed manner. Rna consists of a double helix. A 5 and a 3 end b.

The amount of adenine is equal to the amount of thymine and the amount of guanine is equal to the amount of cytosine The transfer of genetic information from DNA to RNA is called. Two strands of DNA are anti-parallel. The two strands are antiparallel c.

All of the above. The 3 end of the double helix terminates in a nitrogenous base on the 3. Which statement is true.

The two polynucleotide strands are complementary. DNA strands have directionality. Rna consists of a single strand.

The double-helical structure of DNA is primarily stabilized by base-stacking interactions between adjacent bases. This uniformity is due to the base pairing between a purine and a pyramidine. B It takes large amounts of energy to separate the double helix because it is held together via covalent bonds.

The two strands are held together by hydrogen bonds between complementary bases d. The two strands are antiparallel. In a sample of double-stranded DNA 20 of the nitrogenous bases are guanine G.

A Composed of two or more polynucleotide chains. D The amount of adenine is equal to the amount. Bases present extend outward from the.
