Question

The side of the ladder are made up of alternating ____ and ____ molecules the steps of the ladder are made up of _____ held together by hydrogrn

Answer 1

Answer:

The side of the ladder are made up of alternating  deoxyribose sugar and phosohate molecules the steps of the ladder are made up of nitrogenous bases(adenine with thymine and cytosine with guanine) held together by hydrogen bonding.

Answer 2

Answer:

The correct answer is is phosphate and sugar.

Explanation:

Previous research had demonstrated that the building components of DNA, known as nucleotides, are comprised of a deoxyribose sugar, a phosphate group, and one of the four nitrogen bases

• adenine(A)
• thymine (T)
• guanine (G)
• cytosine (C)

1. A lengthy polymer is created when the phosphates and sugars of nearby nucleotides connect.
2. Other significant studies revealed that all living things have constant A: T and G: C ratios.
3. The final indication that the DNA molecule is a double helix with a ladder-like form came from X-ray crystallography.
4. James Watson and Francis Crick at the Cavendish Laboratory in Cambridge, England, won the race to figure out how these components work together to form a three-dimensional structure in 1953.
5. The twisted uprights of the DNA ladder are demonstrated and to be formed by the alternation of deoxyribose and phosphate molecules.
6. The nitrogen bases that make up the ladder's rungs are supportive pairings, A is always coupled with T, and G is always paired with C.
