Answer:
The oligosaccharide is assembled on the lipid carrier at the membrane of the ER
Explanation:
N-linked glycosylation consists of the attachment of an oligosaccharide (glycan) to a nitrogen atom of the asparagine (Asn) residue in the protein. N-linked glycosylation is a key posttranslational modification (PTM) capable of controlling protein structure and function, this pathway takes place in the plasma membrane in archaea organisms and in the membranes of the endoplasmic reticulum (ER) in eukaryotic organisms. In eukaryotic cells, the N-linked glycosylation conserved pathway consists of two steps. In the first place, the oligosaccharides are assembled on a lipid carrier called dolichyl pyrophosphate localized in the endoplasmic reticulum (ER). The dolichyl-phosphatase is a hydrolase enzyme that acts on phosphoric monoester bonds. Second, the oligosaccharides are modified by specific glycosyltransferases that transfer these molecules to selected Asparagine (Asn) acceptor residues of polypeptide chains that have entered the lumen of the ER. These N-glycans are firstly assembled as a dolichol-linked precursor oligosaccharide at the cytoplasmic face of the ER.
Answer:
The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean. ... The rift valley is 1 to 3 km deep, about the depth and width of the Grand Canyon. In contrast, the East Pacific Rise spreads fast at rates of 6 to 16 cm per year (more than 20 cm per year in the past).
DNA helicases "unzip" the DNA molecule in preparation for replication; they break the hydrogen bonds between the two annealed nucleotide bases.
Answer:
A blue room
Explanation:
Green light is the least effective for plants because they are themselves green due to the pigment Chlorophyll.. Blue light helps encourage vegetative leaf growth, and red light encourages flowers. this happens because the amount of blue, red and far red spectrum of light that reaches the planet changes with the seasons. As days start to get longer, more blue spectrum light reaches the surface of the earth. This initiates a vegetative growing stage for most plants leading into the spring and early summer. As the days start to grow shorter, and more of the red and far red spectrum reaches the surface, it leads into the late summer and fall reproductive season.
