DNA- nucleic acids quiz
The strands in a double helix of DNA are: complementary. antiparallel. All of these choices are correct. held together via hydrogen bonds. wound around each other with 10 base pairs per turn.
All of these choices are correct
Consider the structure and function of DNA. Which statement is true? If the sequence of one DNA strand is known, then the sequence of the other strand can be determined. The phosphodiester bonds that stabilize the association of the two strands are easily broken and reformed. Because DNA contains carbohydrates, it provides structural support to the cells. Because DNA is made of phosphate groups that are ionized, it could easily pass through a cell membrane.
If the sequence of one DNA strand is known, then the sequence of the other strand can be determined.
In a deoxyribonucleotide, what chemical group is found at the 2' carbon of the sugar component?
hydrogen
In a double-stranded DNA molecule, the strands are said to be antiparallel because: they form an uneven pair of grooves on the outside of the molecule. only one of them is a template strand. one strand runs in 5′ to 3′ direction and the other in 3′ to 5′. each purine of one strand pairs with a pyrimidine of another.
one strand runs in 5′ to 3′ direction and the other in 3′ to 5′.
