The previous experiment showed that Avicennia marina’s leaf collected from Ekowisata Mangrove Wonorejo, Surabaya, Indonesia contained endophytes. endophytes were known as bacteria which was demonstrated by biochemical tests based on Bergey’s manual of determinative bacteriology . This aimed to characterize the three isolates using Deoxyribonucleic acid. (DNA )sequencing. result isolate 1 and 2 ...

Tetracycline, at concentrations greater than required for inhibition of protein synthesis, rapidly and completely inhibits replication of deoxyribonucleic acid (DNA) in Escherichia coli and Bacillus subtilis. At these concentrations of tetracycline, synthesis of ribonucleic acid is not appreciably altered. In addition to inhibiting DNA replication, tetracycline causes alterations of the cytopla...

Evidence is presented that poxvirus deoxyribonucleic acid (DNA) synthesis required concurrent protein synthesis. The protein requirement in question can be distinguished from viral-induced thymidine kinase and DNA polymerase by virture of the instability of its messenger ribonucleic acid and its stoichiometric rather than catalytic relation to DNA synthesis. The protein(s) required did accumula...

Background The schematic for every living organism is stored in long molecules known as chromosomes made of a substance known as DNA (deoxyribonucleic acid. Each cell in an organism has a complete copy of its DNA, also known as its genomewhich is conveniently modeled as a sequence of symbols (alternately referred to as nucleotides or bases) in the DNA alphabet {A,C,T,G}. In humans, and most mam...

Riboflavin afforded the mutagenic effect on transforming deoxyribonucleic acid (DNA) from Bacillus subtilis through photodynamic action, and upon the addition of adenine to the irradiation mixture the mutagenic effect was greatly accelerated. Most of auxotrophic mutants among the transformants required tryptophan or tyrosine. The mutation was closely correlated with the photodynamic inactivatio...

The deoxyribonucleic acid (DNA) corresponding to the left-hand end of the genetic map is injected first in T7 phage infection. The order was deduced by use of marker rescue experiments to see which genes are still injected after the double-stranded DNA chain is broken by X rays. The treatment causes a selective loss of genes located on the right side of the map. Presumably, this corresponds to ...

Codes have been used for centuries to convey secret information. To a cryptanalyst, the interception of a code is only the first step in recovering a secret message. Deoxyribonucleic acid (DNA) is a biological and molecular code. Through the work of Marshall Nirenberg and others, DNA is now understood to specify for amino acids in triplet codes of bases. The possibility of DNA encoding secret i...
