Answer:
Option (1).
Explanation:
Biological membrane mainly composed of lipids and proteins with the small amount of carbohydrate exposed on the outer surface of the membrane. This membrane plays an important role as it separates the cellular environment and facilitate the transport of the selected molecule.
The flippase enzyme is required to transport the molecules from one side of the membrane to the other membrane. Lipids and proteins can undergo lateral motion but at the different rate within the membrane.
Thus, the correct answer is option (1).
Answer:
50%
Explanation:
According to the given information, the woman has normal BRCA alleles while the man carries one copy of the mutated BRCA allele (BRCA1). A diploid organism such as human beings can have two BRCA alleles. A child gets one BRCA allele from the mother and the other from the father.
The child of the couple would get one normal allele from the woman. However, with respect to the BRCA allele, the man would form two types of gametes in equal proportion. The 50% of his gametes would have the mutated BRCA1 allele while the rest 50% would carry the normal BRCA allele. Therefore, the man can transmit either normal or mutated BRCA allele to the child. So, there are 50% chances for the child to get the mutated allele.
