DNA REPLICATION WHAT IS DNA? DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A)‚ Guanine (G)‚ Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose. THE PROCESS OF DNA REPLICATION How DNA replicates is quite a simple process. First‚ a DNA molecule is "unzipped". In other words‚ it

DNA is the common name for Deoxyribonucleic acid. This is made up of nucleic acids containing deoxyribose (sugar)‚ consisting of complex molecules‚ present in the chromosomes of all plant and animal cells‚ and carrying in coded form instructions for passing on hereditary characteristics. The DNA molecule takes the shape of a double helix‚ a simple structure that resembles gently twisted ladders. The rails of the ladder are made of pairs of nitrogen-containing nucleotides‚ which are subdivisions

plasmid DNA and analysis of isolated plasmid Introduction: A plasmid is an autonomously replicating extra-chromosomal genetic element. In other words‚ this is a DNA molecule external to the bacterial chromosome that is able to replicate on its own and distribute its daughter molecules to daughter cells. You have successfully cloned a fragment of chromosomal DNA containing a tetracycline resistance cassette into a plasmid (pET11a). To this end you have (1) isolated total chromosomal DNA from your

The DNA double helix model In 1953 James Watson and Francis Crick made a scientific breakthrough when they discovered the structure of DNA. From this structure they inferred that DNA contains information written in a genetic code‚ is passed from one generation to the next. This discovery was to be a key step in the genetics revolution DNA has four molecular building blocks called nucleotides; adenine (A)‚ thymine (T) guanine (G) and cytosine (C). Purine base always pairs (by hydrogen bonding) with

With RNA‚ anywhere you would expect to see Thaime‚ you see Uracil instead. 3) DNA has no types‚ RNA has 3 types: mRNA‚ rRNA‚ and tRNA. 4) DNA and RNA have different sugars. 3.

What role does DNA play in inheritance? - DNA is the genetic material of inheritance. Deoxyribonucleic acid (DNA) is the body’s instruction manual for making who you are. DNA is present in any living being. You receive one -half of your DNA from your money and one-half from you Father. People with light eyes tend to carry recessive alleles of the major gene and people with dark eyes tend to carry the dominant alleles. Genes are located on rodlike structures called chromosomes that are found in the
