Cl has nonmetallic properties
Answer:
Mutations in introns create alternative splicing site which in turn make mRNA with reduced or no translation.
Explanation:
Introns regulate the splicing of heterogenous RNA during post transcriptional modifications as well as affect the stability of mature mRNA. The stable mRNA is more likely to be translated into proteins. So, introns also regulate the translation of mRNA.
In human beta thalassemia, mutations in intron create alternative splicing sites which in turn affect the formation of beta globin chain of hemoglobin. Lack of beta globin chain reduces the amount of functional hemoglobin and causes anemia.
The question is asking to choose the following process could the breeder use to determine if Sam is the father of the pups and in my further research and in my own understanding, I would say that the answer would be Y-Chromosome Analysis. I hope you are satisfied with my answer and feel free to ask for more
Facilitated diffusion is the term
given for passive transport of molecules or ions across a biological membrane, facilitated
by transport proteins. The molecules or ions move down a concentration
gradient; therefore, no chemical energy is required and no ATP hydrolysis is
needed. The transport proteins may be responsible for carrying larger molecules
across the membrane by changing their conformation, or water-soluble transport
proteins may carry non-polar molecules with poor water solubility across. Since
no energy is involved in the diffusion, options a) and c) are incorrect. Since
the molecules being carried are not altered in any way, option d) is incorrect.
Option b) ‘transport proteins provide a hydrophilic route for the solute to
cross the membrane’ is correct as water-soluble carrier proteins are able to facilitate
the diffusion of non-polar molecules with poor water solubility.
