segmentation gene造句

• We can also expand on the different classifications of segmentation genes Biology online
• Two additional classes of segmentation genes are expressed after the gap gene products.
• *There are several published scientific articles that discuss segmentation gene in " Drosophila ".
• The gap genes are part of a larger family called the "'segmentation genes " '.
• The segmentation genes specify 14 " parasegments " that are closely related to the final anatomical segments.
• *There is an evolutionary transcription regulatory relationship within segmentation gene networks that can be referenced as well as how segmentation genes act as transcription factors.
• *There is an evolutionary transcription regulatory relationship within segmentation gene networks that can be referenced as well as how segmentation genes act as transcription factors.
• There are three fundamental types of genes that give way to the developmental structure of the fly : maternal effect genes, segmentation genes, and homeotic genes.
• In the early fly embryo, the gap gene transcription factors are responsible for activating and repressing a number of segmentation genes, such as the pair rule genes.
• The transcription factors that are coded for by segmentation genes regulate yet another family of developmental control genes, the "'homeotic selector genes " '.
• While the segmentation genes can specify the number, size, and polarity of segments, "'homeotic genes "'can specify the identity of the segment.
• The expression patterns of the final class of segmentation genes, the "'segment polarity genes "', are then fine-tuned by interactions between the cells of adjacent parasegments ( see the example, " engrailed ", Figure 7 ).
