Question

What do you mean by DNA sequencing?

Choices

Choice (4) Response
a.

Technique, which is used to determine the Phosphate sequence in a DNA molecule

b.

Technique, which is used to determine the sugar sequence in a DNA molecule

c.

Technique, which is used to determine the base sequence in a DNA molecule

d. None of the above

Answer

c.

Explanation

DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. It includes the technology that is used to determine the order of the four bases—adenine, guanine, cytosine, and thymine—in a strand of DNA.

Figure shows an influenza virus

Above figure shows the structure of influenza virus

Choices

Choice (4) Response
a.

A- membrane envelope, B-Protein Coat, C- RNA

b.

A- Fiber, B- RNA, C-Nucleic acid

c.

A-Nucleic Acid, B-RNA, C-Protein Coat

d.

A-Protein Coat, B-Tail, C-Membrane envelope

Answer

a.

Explanation

The genome of influenza A and B viruses consists of single stranded RNA of negative sense. Influenza virus are a small number of M2

Protein molecules, which function as ion channels and protein coat surrounded the nucleic acid

Passage

The diagram shows two solutions of strong glucose and weak glucose solution, which are separated by a partially permeable membrane. This membrane will allow the transfer of water molecules not glucose molecules.

Question

The above diagram shows which type of process?

Choices

Choice (4) Response
a.

Osmosis

b.

Dissolution

c.

Reverse osmosis

d.

Active transport

Answer

a.

Explanation

Osmosis is the result of diffusion by a semipermeable membrane. A semipermeable membrane separates two different concentration’s solution and movement across the membrane from the low solute concentration to the more solute concentrated solution. This process is called osmosis.
