Answer:
The role of CFTR is to build channels on the cell surface to enable the flow of chloride (Cl-). When the CFTR protein works properly, the balance of Cl-and fluid at the cell surface is normal. If the mutation of CFTR protein happens the balance of Cl- and fluids is disrupted, causing mucus in various organs to become thick and gluey. As a result, lung infections and, eventually, respiratory failure in the lungs might occur. Mutations on the CFTR normally change single amino acids in the CFTR protein which happens in abnormal channel breaks down soon after it is made.
Explanation:
The CFTR gene gives direction for producing a protein called the cystic fibrosis trans membrane conductance regulator. This protein functions being a channel over the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.The channel transports negatively filled particles called chloride ions into and out of cells.The transport of chloride ions improves control the movement of water in tissues, which is essential for the creation of thin, freely flowing mucus. Mucus is a slippery substance that greases and defends the lining of the airways, digestive system, reproductive system, and different organs and tissues.The CFTR protein further regulates the role of other channels, such as those that transport positively charged particles called sodium ions across cell membranes. These channels are essential for the normal function of organs such as the lungs and pancreas.
The answer would be:
C. Transcription
Here's a little more about gene regulation:
Gene regulation as mentioned already, is the process of turning genes on and off. In multicellular organisms, the different cells have the same DNA in them but through gene regulation, different sets of genes are expressed. The genes that are expressed determine the function and appearance of the cell.
Answer:
the answer is c
Explanation:
because study island said so lol
Answer:
Pioneer species are hardy species which are the first to colonize previously biodiverse steady-state ecosystems. Some lichens grow on rocks without soil, so may be among the first form of life. The example includes bacteria, fungi, and lichens.
Answer:
B- The phenotype of the progeny reveal the allelic content of the gamete from the heterozygous parent.
Explanation:
Normally, such tests are used to identify the allele content of the parent, to determine the gene dominance and recessiveness. That is, which gene is dominant ,and which is recessive. These would enable easier mapping of traits of newly found species.
