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.
False: Fats are derived from different foods inside most food groups, and aren't exclusive.
A scientist will test it and support it with things so the scientist knows its true and that should be a theory no longer a hypothesis if they proved the information.
Answer:
Rocks are also subjected to the three types of directed (non-uniform) stress – tension, compression, and shear. Tension is a directed (non-uniform) stress that pulls rock apart in opposite directions. The tensional (also called extensional) forces pull away from each other.
Explanation:
There are some characteristics that scientists considered before they classify organisms, these characteristics include the following:
1. The number of cell present in the organism: on the basis of number of cell, an organism can be classified as a prokaryote or an eukaryote.
2. Mode of feeding: an organism can be categorized as an autotroph or a heterotroph based on the way it obtains its food.
3. Mode of reproduction: an organism can be classified as sexual or asexual based on the method it uses to reproduce its offspring.
