The following experiments related to vulva development in C. elegans were performed: • When the anchor cell was killed by laser beam at early embryonic development and embryo was allowed […]

In C. elegans, an anchor cell and a few hypodermal cells take part in the formation of vulva. The experiment performed to understand the role of these cells in vulva […]

A group of six cells called ‘equivalence group cells’ divide to form the vulval structure in Caenorhabditis elegans. They are called so because (1) they have similar fates during development […]

The model organism to study cell lineage is (1) Xenopus (2) Yeast (3) Caenorhabditis elegans (4) Drosophila  Understanding how cells divide, differentiate, and form complex tissues is a central question […]

5 The first organ system to develop during organogenesis is the (1) Integumentary system (2) Respiratory system (3) Excretory system (4) Cardiovascular system Organogenesis—the process by which organ systems are […]

Fusion of precursor cells is an essential phenomenon in development of (1) Nerve (2) Skeletal muscle (3) Spleen (4) Liver Fusion of precursor cells, specifically myoblasts, is a vital and […]

cAMP signalling plays a very important role in the development of Dictyosteliumdiscoideum. Below are few statements related to it. A. Every amoeba at the time of aggregation has the potential […]

cAMP signalling plays a very important role in the development and differentiation of Dictyostelium discoideum. This morphogen’ is synthesized by different adenyl cyclases expressed at different stages of its life […]

The myxamoebae are in the vegetative stage where they feed on bacteria but enter the aggregation stage during nutrient starvation finally forming fruiting body with two types of differentiated cells. […]
