Find an angiosperm that has modified leaves, stems, roots or flowers that do not function in the normal manner, or that function in an unusual manner.

Angiosperms (flowering plants) are the largest Phylum in the plant kingdom (Angiospermophyta is also called Anthophyta or Magnoliophyta). These plants have true roots, stems, leaves and flowers. The roots grow into the soil to anchor the plant in place and take up water and nutrients. The leaves are above ground and act as the main organs for photosynthesis. Stems act as aboveground support for the plant and operate as conduits to move nutrients and water throughout the plant. Flowers contain the male and female reproductive organs of the plant. With these anatomical features in mind, do some research to find an angiosperm that has modified leaves, stems, roots or flowers that do not func... click for more

What intermediates of nucleotide biosynthesis would accumulate?

The diazo compound O-(2-diazoacetyl)-L-serine is a powerful inhibitor of glutamine amidotransferases. If growing cells are treated with this compound, what intermediates of nucleotide biosynthesis would accumulate. Please explain your answer.

Propose a possible mechanism for growth hormone signaling.

Human growth hormone binds to a cell surface membrane protein that is not a receptor tyrosine kinase. The intracellular domain of the receptor can bind other proteins inside the cell. Furthermore, studies indicate that the receptor is monomeric in the absence of hormone but dimerizes on hormone binding. Propose a possible mechanism for growth hormone signaling.

What positions are labeled in the two nucleotides?

Purine biosynthesis is allowed to take place in the presence of [N15]aspartate, and the newly synthesized GTP and ATP are isolated. What positions are labeled in the two nucleotides?
