When usingthe standard proteins it is typically assumed that the vv values of thestandard and actually measured protein are identical. With thisassumption, the ratio of the molecular masses of the two proteins isidentical to the ratio of their I(0)s normalized against the concen-trations.
The gametes (an egg and a sperm) fuse in the process of syngamy to form a 2 n zygote. The zygote divides mitotically to form a multicellular embryo ( embryogenesis), which is protected by either gametophytic tissues (such as remnants of archegonia in the nonseed land plants) or sporophytic tissues (the seed in the seed plants). An embryo,...
An embryo is an early stage of development of a multicellular diploid eukaryotic organism. In general, in organisms that reproduce sexually, an embryo develops from a zygote, the single cell resulting from the fertilization of the female egg cell by the male sperm cell. The zygote possesses half the DNA of each of its two parents.
