DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
Answer:
Explanation:
From the given information:
Since the parent are normal; Let assume that their trait is Pp
The affected sister will be recessive in nature, so the trait will be pp
Now, the husband who is the groom will be a carrier with a probability of 2/3 since her sister is affected.
Also, the wife will be carrying a heterozygous trait since she is normal as well.
However, using Hardy-Weinberg assumption:
q = 0.02
Recall that:
Thus, 
2pq = 0.0392
Finally, the required probability that there will be an affected offspring amongst the family is:
Answer:
Anabolic reactions use ATP and small substrates as building blocks to synthesize larger molecules.
Explanation:
Anabolic reactions are part of metabolic pathways that occur inside the living cells. Anabolic reactions always form complex molecules from simpler substances. The formation of glucose from relatively simpler CO2 and H2O during the Calvin cycle is an example of the anabolic pathway. During anabolic pathways, the metabolic energy of ATP hydrolysis drives the endergonic reactions. Therefore, anabolic reactions consume ATP. Calvin cycle uses the ATP produced during light reactions of photosynthesis.
The first thing is that the enzyme, DNA helicase
breaks the hydrogen bonds to unzip the double strand of dna for replication to take place
This phenomenon is called Eclipse.
