GC-MS can be used to separate and identify proteins, and HPLC is commonly used to separate lipids (T, F).

Why would the nucleotide bases be represented as puzzle pieces, as in the illustration below? What does this representation tell you about how bases pair up? Include in your answer the following terms: adenine, cytosine, guanine, and thymine. A T

Use the information on the proteins given to solve the questions:  A. Draw a UV-Vis spectrum of each protein (A, B, C, and D) from 240 – 480 nm if they were all present at 20 µM.  B. How can you create a two-step purification procedure that could be used to purify protein A from the other proteins. In addition, include a chromotagram as well.

please help me, I am using this to study but I do not know if my answer is correct.

Classify the symmetrical arrangement ofthe subunits (e.g., C2 , C3 , D 2 , helical, icosahedral). 1. Proteobacterial nitrite sensor (3PNS):2. Pseudomonad oligosaccharide receptor (7POR):3. Adenoviral structural protein (8ASP)
