Statement (S): Less than $2\%$ of the human genome encodes for functional units called 'proteins'.

Reason (R): The majority of the human genome is regulatory in nature.

Which of the following is true?

Statement I: Organs which have similar structure and origin but perform different functions are called analogous organs.

The correct option among the following is

Match the following

The correct match is

Reason (R): Wings of sparrow and finches are homologous

Observe the illustration and answer the questions.

Write any two other scientific evidences which proves evolution.

Study the following statements
I) Gene that codes for the synthesis of dystrophin is the largest human gene
II) Chromosome $21$ contains the highest number of genes
III Endonucleases are used to cut the DNA at specific region
IV) Whole hereditary information encoded in DNA of an organism is called genome

Among the above identify the correct statements

Match List$-\mathrm{I}$ with List$-\mathrm{II}$.

Assertion (A): There is a sufficient reason to believe that first cells on the planet lived in an atmosphere lacking oxygen.
Reason (R): Thus even all living organisms retain the enzymatic mechanism to completely oxidise glucose without the help of oxygen. 

The correct option among the following is:

The correct match is
