Answer:
P53 protein is a tumor supressor protein.p53 is so named because it has a molecular weight of 53 kd.p53 is encoded by TP53 gene.p53 is called the guardian of the genome because it helps to maintain balance between live cells and dead cells.
Explanation:
p53 is an important regulatory protein of apoptosis or programmed cell death.p53 helps in the destruction of damaged cells or cell with damaged DNA thus ensuring that every cell in our body has normal DNA.
Mutation of p53 result in the generation of cancer because p53 is a potent regulator of cell cycle.
p53 destroy the damaged cells by activating p21 which in turn blocks G1 cyclin CDK thus blocking the cell to enter the S phase or synthesis phase.
Mutation in p53 result in the progression of abnormal cell through the cell cycle which ultimately result in formation of abnormal protein thus giving rise to the onset of cancer.
Because with a DRI we know the average or ballpark estimate on hwo much of a certain nutrient we should take in/consume per day. This goes for all the macronutrients as well as the micronutrients. Knowing this information, we can guarantee a healthy and balanced diet.
This is an overview of translation process.
Translation is the process in protein synthesis in which the genetic information encoded in mRNA is translated into sequence of amino acid in polypeptide chain.
Ribosomes bind to mRNA in the cytoplasm and move along the molecule in a 5 prime to 3 prime directon until it reaches a start codon i.e AUG. Anticodons on tRNA molecules align opposite appropriate codons according to complementary base pairing (e.g. AUG = UAC). Each tRNA molecule carries a specific amino acid (according to the genetic code)
. Ribosomes catalyse the formation of peptide bonds between adjacent amino acids (via condensation reactions)
. The ribosome moves along the mRNA molecule synthesising a polypeptide chain until it reaches a stop codon
. At this point translation ceases and the polypeptide chain is released
Answer:
A.
Explanation:
The vaccine is dead/weakened pathogens injected to cause antibodies. These antibodies will recognize the pathogens if they see them and fight them off.
Hope this helped! Good luck!
