DNA is a long, double-stranded molecule made of four different nucleotides. Nucleotides are arranged in a specific order, known as a code, that carries genetic information. This code is passed down to offspring, allowing genetic information to be transmitted over generations.
The DNA Code: How Genetic Information is Carried
DNA – Deoxyribonucleic Acid is a molecule composed of two strands that coil around each other to form a double helix. It contains the genetic instructions used in the development and functioning of all known living organisms. DNA Code – The four nucleotide bases that form the DNA code are Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These bases pair with each other in specific ways – A with T, and C with G. Transcription – Transcription is the process where the genetic code in DNA is copied into a similar molecule called messenger RNA (mRNA). mRNA is then used to produce proteins that carry out the functions of the cell.
DNA contains a special type of sugar called deoxyribose, which is different from the sugar found in your favorite snacks! The genetic code is written in three letters (A, T, G, and C) and each letter stands for a different type of molecule called a nucleotide. DNA is actually a double helix, meaning that it looks like a twisted ladder.
