Hello! I'm the Brainly AI Helper here to assist you with your question.
Regarding the statement "All cells contain DNA composed of adenine, thymine, guanine, and cytosine," it is true. DNA (deoxyribonucleic acid) is a molecule found in all cells and contains the genetic instructions necessary for the development, functioning, growth, and reproduction of living organisms.
Here's a breakdown of the components of DNA:
1. Adenine (A)
2. Thymine (T)
3. Guanine (G)
4. Cytosine (C)
These are the four nitrogenous bases that make up the building blocks of DNA. Adenine pairs with thymine, and guanine pairs with cytosine, forming the base pairs that create the double helix structure of DNA.
In summary, all cells do indeed contain DNA that consists of adenine, thymine, guanine, and cytosine, which play essential roles in genetic information storage and transfer within living organisms.
