Answer:
All of the other answer choices suggest the presence of a multipass transmembrane protein.
Explanation:
The primary sequence contains stretches of polar and nonpolar amino acids, suggesting an amphipathic design.
This one could be, because of the presence of polar an nonpolar aminoacids. The phospholipids membrane have the same construction.
The protein has windows of the primary sequence with positive hydropathy values separated by windows of the primary sequence with negative hydropathy values.
The same here, having pieces of positive and negative hidropathy can be a sign of transmembrane protein.
The protein isolates with the membrane fraction of the cell rather than the cytoplasmic fraction of the cell.
This is discribing you a transmembrane protein
The answer is C. <span>Sister chromatids align in the middle; cytoplasm pinches in to separate daughter cells.</span>
Umbilical vein transports blood rich in oxygen and nutrients from the placenta to the fetus. The unpaired umbilical vein is a vein present during fetal development and it transports the nutrient- and oxygen-rich blood from the placental villi via the umbilical cord to the embryo. The umbilical vein is connected to the two intraembryonic umbilical veins.
Answer:
The correct answer will be option-F.
Explanation:
The DNA transformation is the horizontal transfer of DNA in which the DNA is taken up by the competent bacterial cells from the surrounding.
The transformation process was studied by the Griffith in 1928 in <em>Streptococcus pneumoniae</em>- R and S- strains in which R-strain bacteria took the DNA from the surrounding environment and became S-strain.
The cells become competent by changing their cell wall composition and take DNA after which the DNA gets integrated with the genome of the bacteria through homologous recombination. The bacteria thus acquires the new feature as a result of this integration with genome which is transferred to the offsprings.
Thus, option-F is the correct answer.
