"WebAnswer: Because RNA can hybridize to both strands, the RNA must be transcribed from both strands. This does not mean, however, that both strands are used as a template within each gene. The expectation is that only one strand is used within a gene but that different genes are transcribed in different directions along the DNA. " - How many strands are there in rna

Web27 okt. 2014 · There are four bases: adenine, guanine, cytosine, and thymine. Both adenine and guanine are purines which have a double ring structure. Cytosine and thymine are pyramidines which consist of a single ring structure. The DNA molecule is double helix, a spiral shaped ladder. WebIn its natural state, each DNA molecule is actually composed of two single strands held together along their length with hydrogen bonds between the bases. Watson and Crick proposed that the DNA is made up of two strands that are twisted around each other to form a right-handed helix, called a double helix.
