Answer:
The stop codon mutation in Lucy's ADA gene stopped her ADA protein from working by putting a hault to the process of translation.
Explanation:
This stopped it from working because it lead to a protein that was then nonfunctional.
Answer:Traits are determined by genes, and also they are determined by the interaction with the environment with genes. And remember that genes are the messages in our DNA that define individual characteristics. So the trait is the manifestation of the product of a gene that is coded for by the DNA.
Explanation:
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds betweenmonosaccharides. A dehydration synthesis reaction forms a bondbetween carbon atoms in twomonosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
Answer:
The cause of respiratory distress syndrome in premature infants is <u>lack of surfactant in the lungs because the lungs has not fully developed.</u>
Explanation:
Respiratory distress syndrome is a type of neonatal disease of respiration caused by the lack of surfactant production by the lungs.
Normally the lungs of fetus start the formation of surfactant during the third trimester of pregnancy (26 weeks through labour and delivery ). The surfactant is produced by type II alveolar cells and is the lipoprotien complex that has surface tension lowering effect (surface active agent ) having both hydrophobic and hydrophilic properties thus coats the air sacs and alveoli.
In the premature infants, the lungs are not fully developed hence the adequate amount of surfactant is missing thus resulting in Respiratory distress syndrome.
