The inherited traits of an organism are controlled by?
Answer Details
The inherited traits of an organism are controlled by DNA (Deoxyribonucleic Acid) molecules. DNA is a long, double-stranded molecule that contains the genetic information of an organism. This genetic information is stored in the sequence of four types of nucleotides, which are the building blocks of DNA. The nucleotides are adenine (A), cytosine (C), guanine (G), and thymine (T). The sequence of these nucleotides determines the genetic code, which specifies the traits an organism inherits from its parents.
When a cell divides, it copies its DNA so that each new cell gets a complete set of genetic instructions. This process is called DNA replication. During replication, enzymes help unwind the DNA double helix and make copies of each strand. The copies are then used to build new DNA molecules that are identical to the original.
So, to summarize, the inherited traits of an organism are controlled by DNA molecules, which store the genetic information in the form of a specific sequence of nucleotides.
