What Is DNA? Summary, Structure, and Importance

WebMar 22, 2024 · A segment of DNA that codes for the cell’s synthesis of a specific protein is called a gene. DNA replicates by separating into two single strands, each of which serves as a template for a new strand. The new strands are copied by the same principle of hydrogen-bond pairing between bases that exists in the double helix. WebThe way in which eukaryotes compact and arrange their chromatin not only allows a large amount of DNA to fit in a small space, but it also helps regulate gene expression.

WebDNA plays a role as a traffic cop for the types of proteins a cell will make. It does this with proteins in the cells that cause only specific genes to express themselves. Conclusion DNA structure is easy to understood by starting from its smallest units and moving to its largest form. In the next article, we’ll look at the full form of human DNA. WebThe base pairs form the rungs of the twisted ladder, and the sugar-phosphate strands form the sides. There is so much DNA in each tiny cell that it must be condensed further to fit inside. The DNA is tightly coiled into structures called chromosomes. Humans typically have 46 chromosomes – 23 from each parent.
