Answer:
If there is a mutation in the p53 protein then this leads to abnormal cell growth and cell death or apoptosis does not occur.
Explanation:
p53 is a tumor supressor protein.p53 is encoded by TP53 gene.The protein is named so because the protein has a molecular weight of 53 kilo Dalton and this protein helps in programmed cell death or apoptosis.
The mutation in p53 result in the abnormal cell growth due to accumulation of mutated p53 protein, an important sign of development of cancer.
B- evolution. Decent with modification was an early theory (of evolution) that was set out before people had any idea about genetics and how traits were transferred
Proteins are molecules made of amino acids. They are coded for by our genes<span> and form the basis of living tissues. They also play a central role in biological processes. For example, proteins </span>catalyse<span> reactions in our bodies, transport molecules such as </span>oxygen<span>, keep us healthy as part of the </span>immune system<span> and transmit messages from </span>cell<span> to cell.</span>
Information is not passed on through DNA but through molecules having an influence on the DNA of the new generation.
This is one argument against Lamarck's ideas.
