Directions in L2 Writing Assessment growth. Recently we have adapted many human tumor lines to replicate continuously in RPMI-1640 medium without any additives. This forces the tumor cells to secrete all of the factors essential for growth. Identification of autocrine growth factors offers several therapeutic strategies to prevent tumor replication.

Regulation of gene expression by indoleacetic acid in pea epicotyl tissueghly specific to auxins, and does not require concurrent protein synthesis. The data indicate that auxin augments the amount of specific mRNAs rather than alter the translatability of preexisting RNAs. The response is the fastest known for any plant growth regulator and qualifies as a primary hormonal response to auxin.
