Dominant allele: an allele that has the same effect, Recessive allele: an allele that only has an effect on, Codominant alleles: pairs of alleles that both affect, Locus: the particular position on homologous. Presenting data in an effective way is an important skill of all scientists. Metabolism, the sum of chemical reactions that take place in living cells, providing energy for life processes and the synthesis of cellular material. Calculation of the magnification of drawings and the actual size of structures and ultrastructures shown in drawings or micrographs. We now know that one gene is capable of providing multiple, different transcription units of messenger RNA (mRNA), depending on where the replication process begins. If you're an IB Biology teacher here's a challenge (or perhaps not): List and describe the four basic biological concepts that run through the discipline of Biology. Action potential.
