Basically structure of DNA is very important in the process of replication.
DNA molecules have antiparallel structure i.e. the two strands of the halix run in opposite directions of one another. Each strand has 5 prime end and 3 prime end. Solving the structure of DNA unlocked the door to understanding many of the function of DNA, such as how it copied and how the information it carries can be used to produce protein.
The correct question is : The given statement is True or False
While studying a sample for height differences, researchers observed that the height of the participants varied significantly regardless of whether the participants' parents were short or tall. This suggests that the physical characteristic of height is most likely an example of Polygenetic inheritance.
Answer: True
Explanation:
The poly genetic inheritance can be defined as the characters which is not only controlled by the single gene in the body it is controlled by the multiple genes of the body.
The genes are large in quantity but the effect is very small. There are many characters in the body which is polygenic in nature.
These are height of offspring, skin color of the offspring, eye color of the offspring, et cetera.
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.
Some living thing's bodies are weaker than others. For the species to live, the strong ones of the species will not get sick, reproduce and create strong offspring. The weak will die out.
