Can someone please help me with homeobox genes and apoptosis. I am clueless as I don't understand these at all so I hope somebody could help me. Thank you!
Keep calm and breathe lol.
Homeotic genes are similar in plants, animals and fungi. They control the development of body plans and are expressed in specific patterns in particular sequences of development depending on when they are activated.
Homeobox genes are a short length of DNA that code for around 60 amino acids. They are found in most, if not all eukaryotes. This section binds to DNA to regulate transcription.
In animals, homeobox genes are concerned with segmentation, establishment of anterior-posterior axis and the activation of genes involving the development of body parts such as limbs.

THANKS! I have heard from a lot of people that this could come up..... so ideally, it would be a good idea to learn it before the exam.
heellpp..what part of brain controls somatic nervous system? i know automatic is controlled by combination of hypothalamus (sympathetic in fight or flight) and medulla oblongata!!!!
Synapse Neurotransimtter : Noradrenaline/Various Smooth presynaptic membrane More postsynaptic receptors Action potential is not always amplified. I.e. if the stimulus is weak it will not excite the postsynaptic membrane to the threshold level
Neuromucular Junction Neurotransmitter : Acetylcholine Has clefts on the presynaptic membrane Fewer postsynaptic receptors The muscle will always contract

well.. motor areas in the cerebral cortex send impulses to effectors (voluntary muscles/glands) for muscular movements. So maybe the cerebrum/cerebral cortex does?
