Very Short Question and Answers - DNA

DNA stands for Deoxyribonucleic Acid.

DNA is located in the nucleus of almost every cell.

DNA has a double helix structure, resembling a twisted ladder, with steps made of chemical bases (Adenine, Thymine, Guanine, Cytosine).

DNA stores genetic information, acting as a blueprint for building and running an organism.

A gene is a specific segment of DNA that contains instructions for making a particular protein.

Proteins are made based on the instructions in DNA, specifically those provided by individual genes.

DNA contains genes, genes provide instructions to make proteins, and proteins result in the expression of specific traits in an organism.

In pea plants, a 'tallness gene' controls whether a plant is tall or short.

Traits are passed through DNA, which is inherited from both parents during reproduction.

Mendel found that traits follow patterns of inheritance based on genes present in DNA, such as dominance and recessiveness.

Inheritance is the process by which traits are passed from parents to their offspring through DNA.

Bases are chemicals that form the steps of the DNA ladder; they are Adenine, Thymine, Guanine, and Cytosine.

DNA contains genes that determine characteristics like flavor, color, and nutrition, influencing the quality of produce.

Genetically modified crops are plants whose DNA has been altered to express desired traits, like Bt cotton that resists pests.

Scientists identify DNA that gives natural disease resistance and breed plants with these genes to create disease-resistant crops.

Children inherit DNA from their parents, which carries genes responsible for physical and other traits.

DNA contains genes that can influence yield, and selecting or modifying these genes can help produce higher-yielding crops.

Proteins, made from gene instructions, perform functions that lead to the physical and functional traits observed in an organism.

DNA helps in understanding, selecting, and modifying traits to create better crops with desired features like yield, taste, and resistance.

The double helix protects genetic information and allows for accurate copying and transfer during cell division.
