Give an explanation why a mutation in the fibroblast growth factor receptor (FGFR) can disrupt embryonic development, even if the individual is heterozygous for this mutation.
ANS)
--> FGFR3 quality encodes Fibroblast development consider receptor 3 protein people and is spoken to as CD333 (a bunch of separation 333). This quality is situated on chromosome 4, area p16.3 and the outflow of this receptor protein happens in ligament, cerebrum, digestive system, and kidneys. At the point when there is a transformation in this quality distinctive ailments are made and one among them is a birth infection called Achondroplasia. FGFR3 is a transmembrane receptor protein along these lines it partakes in flag course amid embryonic and fetal improvement. It has a significant job in vein arrangement and neural separation. Achondroplasia is brought about by a solitary nucleotide substitution in this quality, where a change of amino corrosive happens (Gly380Arg). Achondroplasia is an autosomal overwhelming legacy that is the reason it happens even in the heterozygous conditions.

The growth factor was a signalling molecule that bound to a receptor. channel Okinase O G-protein contact-dependent Question 10 2 pts Which of the following best explains why dimerization of the kinase receptor in the absence of a growth factor could lead to cancer? The dimerization produces the growth factor, which can the signal for the cell to divide even if it was not supposed to. O Dimerization would cause the alpha subunit of a G-protein to become activated, leading...
2. The following is a description of a signaling pathway initiated by receptor tyrosine kinases. Ligand → RTK → Sos → Ras → Raf → MEK → ERK → Transcription factor → Cell growth A. (3pts) Which of these steps indicates the protein is activated after a GTP exchange step? B. (3pts) Which of these proteins can be deactivated by phosphatases? C. (4pts) Describe a mutation that would cause Ras to be permanently "on"? Would this mutation lead to high...
Describe five different ways by which antibiotics can disrupt bacterial cells and cell growth. Give an example of each .
What mechanisms have we encountered that ensure that a signal initiated by a growth factor receptor can be greatly amplified as the signal is transduced down a signaling cascade in the cytoplasm? Conversely, what signaling cascade(s) strongly limit the possible amplification of a signal initiated at the cell surface?
Please answer 2-5 2. Consider a gene with a particular function. Mutation X and mutation Y cach cause defects in the function of the encoded protein, yet a gene containing both mutations X and Y encodes a protein that works even better than the original protein. The odds are exceedingly small that a single mutational event will generate both mutations X and Y. Explain a simple way that an organism with a mutant gene containing both mutations X and Y...
Pertuzumab is a recombinant monoclonal antibody that targets the human epidermal growth factor receptor 2 (HER2) protein. Pertuzumab can be used in the treatment of specific metastatic breast cancers in patients who have not received prior anti-HER2 therapy or chemotherapy for metastatic disease. The HER signaling pathway plays a role in the formation and growth of numerous cancers, and pertuzumab binds to the HER2 receptor to inhibit the ability of HER2 to interact with other HER family members on the...
Pls give short answers. Thank you Q5 EGF pathway 23 Points A EGF EGFR GRB2 SOS KRAS Active RAS KRAS GOP GDP GTP RAF РІЗК MEK АКТ) ERK Growth and Suppression Proliferation of Apoptosis Shown is the EGF signaling pathway. This is a pathway that normally promotes growth during development, and inhibits apoptosis (or programmed cell death). This pathway is also involved in cancer. Epidermal growth factor (EGF) binds to its receptor (EGFR). This binding activates the protein KRAS, which...
Population growth can be both a positive and negative factor for living standards. Explain why this is so.

Can someone give a thorough explanation of why? Thank you so much!! 4. If V is known at only a single point in space, can E be found at that point? Explain your answer.
