The DNA molecule is made up of O a. 4; 2 Ob. 1; 1 O c. 2; 1 O d. 1; 2 O e. 2; 4 QUESTION 45 The formation of large molecules from small subunits is known as what kind of reaction? O a reduction O b.condensation Oc decarboxylation d. hydrolysis O e. oxidation

Answer 1

44. Ans:

c. 2;1.

- DNA is made up of two strand coding and non coding strands. Coding strands are known as template strand on which replication take place. But RNA is single strand on which translation take place e.i protein synthesis.

45. Ans:

b. Condensation

- in condensation reaction number subunits molecules or compound combine together to form large molecules.

Example: condensation of Oxaloacetate with acetyleCo-A to citric acid or citrate.

46. Ans:

a. Ions.

- when atom lose or gain electron an ions is from either +ve or -ve.

example: Chlorine(Cl) lose gain electron to from negative ion (Cl^{​​​​​-}​)

Sadium(Na) loose electron to form positive ion (Na
