Chloroplast DNA codes for transfer RNA . Jan
Transfer RNA's were isolated from Euglena gracilis. Chloroplast cistrons for tRNA were quantitated by hybridizing tRNA to ct DNA. Species of tRNA hybridizing to ct DNA were partially purified by hybridization-chromatography. The tRNA's hybridizing to ct DNA and nuclear DNA appear to be different. Total cellular tRNA was hybridized to ct DNA to an equivalent of approximately 25 cistrons. The tot...
متن کاملChloroplast-like transfer RNA genes expressed in wheat mitochondria.
In the course of a systematic survey of wheat mitochondrial tRNA genes, we have sequenced chloroplast-like serine (trnS-GGA), phenylalanine (trnF-GAA) and cysteine (trnC-GCA) tRNA genes and their flanking regions. These genes are remnants of 'promiscuous' chloroplast DNA that has been incorporated into wheat mtDNA in the course of its evolution. Each gene differs by one or a few nucleotides fro...
متن کاملPreferential transcription of cloned maize chloroplast DNA sequences by maize chloroplast RNA polymerase.
Zea mays chloroplast DNA-dependent RNA polymerase in vitro preferentially transcribes maize chloroplast DNA sequences incorporated in cloned chimeric bacterial plasmids. Preferential transcription is dependent on the presence of a 27.5-kilodalton polypeptide, the S factor, which has been purified from maize chloroplasts, and also on the template's being in the supercoiled form.
متن کاملDNA codes for nanoscience.
The nanometer scale is a special place where all sciences meet and develop a particularly strong interdisciplinarity. While biology is a source of inspiration for nanoscientists, chemistry has a central role in turning inspirations and methods from biological systems to nanotechnological use. DNA is the biological molecule by which nanoscience and nanotechnology is mostly fascinated. Nature use...
متن کاملExordium for DNA Codes
We describe how deletion-correcting codes may be enhanced to yield codes with double-strand DNA-sequence codewords. This enhancement involves abstractions of the pertinent aspects of DNA; it nevertheless ensures specificity of binding for all pairs of single strands derived from its codewords—the key desideratum of DNA codes– i.e. with binding feasible only between reverse complementary strands...
