Answer 1

Answer:

1. The given diagram is structure of DNA.

2. A double helix structure.

3. Adenine Thymine Guanine Cytosine are nitrogenous bases.

4. the rails of DNA made up of deoxyribose sugar and phosphoric acid.

Answer 2

➡Observe the given diagram and answer the following

1. Identify the given diagram?

Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses. DNA and ribonucleic acid are nucleic acids.

2. DNA has two parallel threads, what is this structure called?

⚫DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .

3. Name nitrogenous bases.

⚫adenine, cytosine, uracil, and guanine..

4. From which substances each rail of the DNA ladder is made up of?

⚫The rails of the DNA strand are made up of deoxyribose (a sugar) and phosphoric acid. These two molecules alternate one after the other the entire length of the rail. The rungs of the DNA strand are made up of organic bases. These organic bases attach to the deoxyribose on the ladder rails.
