according to research, academic self-concept and academic achievement are mutually interdependent. in the present study, the aim was to determine the relationship between the academic self-concept and the academic achievement of students in english as a foreign language and general subjects. the participants were 320 students studying in 4th grade of high school in three cities of noor, nowshah...
The structure of the gene encoding chain c of the hemoglobin of the earthworm, Lumbricus terrestris.
The complete nucleotide sequence of the gene for chain c of hemoglobin of the earthworm Lumbricus terrestris has been determined. The sequence of 4037 base pairs (bp) includes about 310 bp of 5'-flanking sequence and 110 bp 3' to the poly(A) site. Comparison of cDNA and genomic sequences shows four silent differences in codons that suggest the presence of at least two genes. The coding sequence...
متن کاملStoichiometry of subunits and heme content of hemoglobin from the earthworm Lumbricus terrestris.
The extracellular hemoglobin (Hb) of the earthworm, Lumbricus terrestris, has four major O2-binding chains, a, b, c (forming a disulfide-linked trimer), and d ("monomer"). Additional structural chains, "linkers," are required for the assembly of the approximately 200-polypeptide molecule. The proportion of linker chains had been reported to be one-third of the total mass on the basis of densito...
متن کاملA study of the subunit structure of the extracellular hemoglobin of Lumbricus terrestris.
The dissociation of the extracellular hemoglobin of the earthworm Lumbricus terrestris was investigated. At neutral pH, its sz00,~ = 58.9 f 0.2 S and D:o,w = 1.61 f 0.05 X 1O-7 cm2 s-l corresponded to a molecular weight of 3.23 f 0.18 x 106. A minimum molecular weight of 24,000 per heme group was determined from the iron and heme contents, 0.221 f 0.011 weight % and 2.78 =k 0.14 weight %, respe...
