North, J. C.; Dent, M. T. – Journal of Biological Education, 1978
A FORTRAN program is described which simulates point-substitution mutations in the DNA strands of typical organisms. Its objective is to help students to understand the significance and structure of the genetic code, and the mechanisms and effect of mutagenesis. (Author/BB)

Barnett, S. A. – Journal of Biological Education, 1977
Students of ethology are often confused about the validity of arguments based on comparisons of animal and human behavior. The problem can be dealt with purely theoretically or through observational or experimental studies of human behavior. Some results of using these two methods are described and discussed. (Author/MA)

King, B. – Journal of Biological Education, 1977
Experiments are described in which inhibitors are used to investigate the timing of transcription and translation of the messenger RNA for the enzyme invertase. It is suggested that plant tissue slices provide adaptable material with which to study enzyme induction, protein synthesis, and cell differentiation at sixth-form level. (Author/MA)

Jungwirth, E. – Journal of Biological Education, 1977
Respondents' awareness of the problems involved with using anthropomorphic statements in secondary biology instruction was acute in the science education group, but progressively less so with the teachers, the scientists, and the prospective teachers. It was recommended that all persons connected with science teaching become more aware of the…

Gould, C. D. – Journal of Biological Education, 1978
A survey of the place of practical work in sixth-form biology teaching is described. Changes in the declared aims of teachers since 1962 are examined and discussed in the light of recent curricular changes. Some comparisons with similar samples of physics and chemistry teachers are made. (Author/MA)

Freeland, P. W. – Journal of Biological Education, 1977
Described are nine enzyme essays for distinguishing soil samples. Colorimetric methods are used to compare enzyme levels in soils from different sites. Each soil tested had its own spectrum of activity. Attention is drawn to applications of this technique in forensic science and in studies of soil fertility. (Author/AJ)

Dudley, Brian – Journal of Biological Education, 1977
Biological examinations given to 16-18 year olds were analyzed over an eight year period for the number and type of mathematical questions. There was an increase in the number of questions which included skills in graphing, rate, percentage, and statistics. Difficulties with graphs, calculations and indices are discussed. (AJ)
