As shown below, each grid is a square with side length of 1. Arcs centered as the vertices of each grid, with radii of 1 or 2 form the shape below. Find the area of the shaded shapes. (Use π in your response.) 相关知识点: 试题来源: 解析 2π−4 (14×π×22−2×2÷2...
connected via a short hinge region (purple). The N-terminal lobe contains an extended α-helix at the N-terminus, a bound AMP nucleotide (black), the Gly-rich loop (light blue, disordered) and the αC-helix (dark blue). The C-terminal lobe is largely α-helical and...
44.4 square units C. 157.1 square Find the center of mass of the I-quadrant portion of the unit circle centered at the origin of radius 1. Calculate the area of the region inside the circle r = 4cos(theta) and outside the circle r = 2. Points A,...
Full size image The crystal structure contained two PK-1 protomers in the asymmetric unit, which closely associate to form a parallel, side-to-side dimeric assembly (Fig.1b, Supplementary Fig.2a). Analysis using the PDBePISA server19confirmed that the dimer interface was extensive, with a bur...
