DNA characterization

Further studies led to the development of a recombinant microorganism containing a desulfurization enzyme gene at the tail end of a promoter composed of (a) a DNA characterized by a claimed sequence (No. 1 in the referred application) and having...

The first task is somehow to transfer the information from the DNA molecule contained within the nucleus to the site where the protein is to be assembled, that is, to the ribosomes attached to the endoplasmic reticulum. This is the job of m-RNA which is synthesized from DNA in a manner very similar to the synthesis of DNA itself, in a process called transcription. Transcription is controlled by RNA polymerase and because the DNA contains instructions for the manufacture of all the cell s proteins, only a few of which are likely to be needed at any one time, the enzyme must be able to recognize or select which particular DNA regions, representing the desired proteins, need to be transcribed at any one time. It probably does this by attaching to an area of DNA characterized hy having a specific nucleotide sequence - this is the... 

The more complex tertiary structure and quaternary structures of DNA characterize the compacted DNA states present in nucle-osomes and microscopically detected in chromosomes. 

In nucleic acid analysis considerable progress has recendy been reported for methods based on MS. Although ESI-MS can also be used in nucleic acid analysis, MALDI-TOF-MS has been used by most research groups. Various reviews on the use of MALDI-TOF for nucleic acid analysis have appeared, which focus on DNA characterization [516, 517], DNA sequencing [518] and DNA sizing [519].

Deoxyribonucleic Acids as Genetic Material. The substance that makes up the hereditary factors or genes is deoxyribonucleic acid. In general, the current concept is that for each individual gene there is as the chemical equivalent an appropriate DNA characterized by a definite base sequence. The information carried by the gene and finally expressed as a particular character consists in the sequence of the bases. The base sequence in turn determines the primary structure, i.e., the sequence of amino acids, of proteins. There is a direct correlation A certain group of bases of the DNA stands for a certain amino acid in the final protein. 

To analyze the parameters of the cooperation, crosses were performed with transfecting DNA characterized by multipowered dose responses. The following observations were made ...
