Signalling pathways that act coordinately to control vertebrate limb development.

Basic metabolic panel signalling is embedded within a larger network of signalling pathways that act coordinately to control vertebrate limb development. The complex interactions between different signalling pathways are difficult to dissect and the focus of ongoing research. A researcher that you collaborate with is currently working on the sonic-hedgehog signalling pathway. Although the sonic-hedgehog (Shh) […]

What reproductive structure is produced & released from a pollen tube (male gametophyte)?

What reproductive structure is produced & released from a pollen tube (male gametophyte)? 9. What reproductive structure is produced within an embryo sac (female gametophyte)? 10. After double fertilization, the ovule becomes the while the ovary becomes the 1 1. The fertilized ovule is a complex structure consisting of cells with different genotypes & ploidy. […]
