DNA
Virtually anything can be identified by DNA, also known as Deoxyribonucleic Acid. It is a method of identification of growing and living things. According to genome.gov, a DNA molecule consists of two strands that bind around one another to form a shape known as a double helix. Each strand of the double helix has a backbone made of interchanging sugar and phosphate groups. “DNA sequencing is a scientific technique used to define the exact arrangement of bases in a DNA molecule.”(Talking glossary of genetic n.d.) The DNA base categorization transports the information a cell needs to assemble protein and RNA molecules. (Talking glossary of genetic n.d.) RNA, which stands for …show more content…
para. 3) The difference between DNA and RNA is that RNA has the ribose sugar backbone, and has a hydroxyl (-OH) group that DNA does not have. “A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers containing long chains of nucleotides. A nucleotide entails sugar molecules either ribose in RNA or deoxyribose in DNA, attached to a phosphate group and a nitrogen containing base.” (Talking glossary of genetic n.d.) DNA is made out of what is known as nucleotides; consisting of three part groups: a phosphate group, a sugar group and one out of four types of nitrogen bases. These are the building blocks to DNA make up. A chromosome is the outcome of DNA being firmly packed, due to very small organisms such as the nucleus where DNA is found. Organisms require …show more content…
Sequencing the order of amino acids in the polypeptide is determined by 3-letter codes in the messenger RNA. “Synthesis of RNA deriving from a DNA template is known as the transcription process. Only one strand of DNA is imitative. After transcription, the DNA strands rejoin.” (Gene expression n.d) Ribosomes that synthesize proteins consuming the mature messenger RNA transcript produced during the transcription process, happens during the Translation process. Recombinant DNA is produced by merging DNA from two or more outlets. The process frequently consists of conjoining the DNA of different organisms together. This also depends on the ability to expurgate and rejoin DNA molecules at points which are branded by specific patterns of nucleotide bases, which is termed restriction sites. (Recombinant DNA
