Alteration of 5S RNA conformation by ribosomal proteins L18 and L25.
The effects of ribosomal proteins L18, L25 and L5 on the conformation of 5S RNA have been studied by circular dichroism and temperature dependent ultraviolet absorbance. The circular dichroism spectrum of native 5S RNA is characterized in the near ultraviolet by a large positive band at 267 nm and a small negative band at 298 nm. The greatest perturbation in the spectrum was produced by protein...
متن کاملA ribonuclease-resistant region of 5S RNA and its relation to the RNA binding sites of proteins L18 and L25.
An RNA fragment, constituting three subfragments of nucleotide sequences 1-11, 69-87 and 89-120, is the most ribonuclease-resistant part of the native 5S RNA of Escherichia coli, at 0 degrees C. A smaller fragment of nucleotide sequence 69-87 and 90-110 is ribonuclease-resistant at 25 degrees. Degradation of the L25-5S RNA complex with ribonuclease A or T2 yielded RNA fragments similar to those...

15 صفحه اولa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
