In order to have its n-terminus extending into the cytoplasm, the cftr protein must have contained a NBD as the first signal peptide encountered in the primary sequence.

<u>Explanation:</u>

Cystic Fibrosis Trans-membrane conductance regulator (CFTR) exhibits the two domain swap structure and is a protein found in the pancreas, intestinal and respiratory epithelia. The N-terminal signal functions as a first signal peptide.

CFTRs helps in up taking nutrients in prokaryotes and export variety of substrates in the eukaryotes. This NBD nucleotide binding domain acts as the first signal peptide to be encountered in the primary sequence.

Stels [109]
A normal heart rate ranges between 60-100 beats per minute. The higher the heart rate is, the faster the blood is pumping through the heart. When exercising a persons heart will be higher because the brain and the muscles in the body are in need of oxygen so the heart needs to pump faster in order to sustain optimal performance.<span />
