DNA Structure

dna structure  Learn about the structure of DNA and how to recognize all the parts in this video! DNA is made of two dextrogyre helical chains or strands , coiled around an axis to form a double

DNA is a double helical structure composed of nucleotides The two helices are joined together by hydrogen bonds The DNA also bears a sugar-phosphate backbone  Within eukaryotic cells, DNA is organized into long structures called chromosomes Before typical cell division, these chromosomes are duplicated in the process

This means that each of the two strands in double-stranded DNA acts as a template to produce two new strands Replication relies on complementary base pairing, Using this information, Watson and Crick came up with their now-famous model showing DNA as a double helix composed of two intertwined chains of nucleotides, in
