Answer:
They are responsible for determining the general body plan.
They act as master control genes.
They code for DNA-binding proteins.
Explanation:
The homeotic genes are master regulators in development found both in animals and plants. In animals, Homeobox (HOX) genes encode for transcription factors containing a DNA binding domain of 60 amino acids which is evolutionarily conserved in species ranging from Drosophila to humans. In plants, MADS-box homeotic genes encode for proteins containing a conserved DNA-binding domain (in this case, referred to as MADS-box of 60 amino acids), which is capable of controlling developmental pathways in a similar mode to Hox genes in animals. Moreover, it is important to note that MADS-box genes are conserved not only in plants but also in other phyla including animals, fungi and protists.

Agre
verified his hypothesis in anexperiment where he associated cells which includes
the protein with cells that did not have it. When the cells were placed
inside a water solution, those that had the protein inside their membranes
absorbed water by osmosis and increased up. Those that lacked the protein
were unaffected. He also conducted trials with artificial cells called
liposomes, which are a type of soap bubble surrounded by water on its extremities and also inside.
He figured out that the liposomes became permeable to water if the
protein was planted inside their membranes.
Answer:
motor end plate membrane potential,
it applies all or none law. either it generates full threshold level potential or it does not produce any potential. after being released from the presynaptic neuron, ACh binds with the receptor of the postsynaptic neuron, which leads to the depolarization of the cell membrane by the increased transportation of Na and K. then, MEPP leads to increased depolarization in the postsynaptic membrane which is also known as end-plate potential.
A. is the incorrect statement.
Matching codon= CGA
Amino acid = Alanine
