Questions and Answers

1.

What is the primary function of DNA?
- A.
  
  To store genetic material.
- B.
  
  To provide quick, short term energy.
- C.
  
  To provide long term energy.
Correct Answer
A. To store genetic material.

Explanation
The primary function of DNA is to store genetic material. DNA contains the instructions needed for an organism to develop, function, and reproduce. It carries the genetic code that determines an individual's traits and characteristics. This genetic material is passed down from parents to offspring, ensuring the continuity of species. DNA is organized into genes, which are specific sequences of nucleotides that encode for proteins and control various biological processes. Therefore, DNA's main role is to store and transmit genetic information, making it essential for the inheritance and evolution of life forms.

Which of the following best describes the structure of DNA?
- A.
  
  A single strand of nucleotides twisted with a single helix.
- B.
  
  A double strand of nucleotides twisted with a double helix.
- C.
  
  Sugar Phosphate Backbone with four sets of nitrogenous bases: Adenine, Thymine, Guanine, and Cytosine.
- D.
  
  Zigzag Lines with Hexagons and Pentagons
Correct Answer
B. A double strand of nucleotides twisted with a double helix.

Explanation
DNA is a double-stranded molecule made up of nucleotides that are twisted together in a helical structure. This double helix structure is formed by two strands of nucleotides that are complementary to each other, with the bases adenine (A) pairing with thymine (T), and guanine (G) pairing with cytosine (C). This double-stranded structure allows for the replication and transmission of genetic information.

3.

What does DNA stand for?
- A.
  
  Deoxyribonucleic acid
- B.
  
  Deoxyribose acid
- C.
  
  Dioxyglucose acid
- D.
  
  Dioxyribochloric acid
Correct Answer
A. Deoxyribonucleic acid

Explanation
DNA stands for Deoxyribonucleic acid, which is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known organisms. It is composed of two long chains of nucleotides that are twisted together to form a double helix structure. DNA is responsible for storing and transmitting genetic information from one generation to the next. It plays a crucial role in determining an organism's traits and characteristics.

4.

In DNA adenine always pair with?
- A.
  
  Uracine
- B.
  
  Cytocine
- C.
  
  Thymine
- D.
  
  Guanine
Correct Answer
C. Thymine

Explanation
In DNA, adenine always pairs with thymine. This is due to the complementary base pairing rule, where adenine forms two hydrogen bonds with thymine. This pairing is essential for DNA replication and transcription processes, as it ensures the accurate copying and coding of genetic information. Adenine does not pair with uracil, cytosine, or guanine in DNA.

What is the shape of DNA?
- A.
  
  Twisted Ladder
- B.
  
  Esclator
- C.
  
  A cup
- D.
  
  Snake
Correct Answer
A. Twisted Ladder

Explanation
The shape of DNA is commonly referred to as a "twisted ladder" or a double helix. This is because the DNA molecule consists of two strands that are twisted around each other, resembling a ladder that has been twisted. The twisted ladder shape allows for the DNA molecule to be compact and easily replicated, as the strands can separate and new strands can be synthesized along each template. This iconic shape was first proposed by James Watson and Francis Crick in 1953, based on the X-ray crystallography work of Rosalind Franklin and Maurice Wilkins.
