DNA Structure and Replication: Crash Course Biology #10

dna structure  DNA Shape The most common DNA shape illustrated by artists and scientists looks a lot like a twisting ladder Scientists call this a double Chromosomes are structures that look like thread, which live in the nucleus of cells Chromosomes contain DNA and protein, and they

Chromosomal DNA consists of two DNA polymers that make up a 3-dimensional structure called a double helix In a double helix structure, the strands of DNA Notice that in the two figures above, the two strands of a DNA molecule are antiparallel, that is, they run in different directions The side of the chain on

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  DNA structure - double helix structure
