Question
Chapter 19.5, Problem 1CC
Summary Introduction
To predict:
The difference in Davis’s experimental results on using a filter with larger pore; thereby, allowing passage of cells.
Introduction:
Davis’s experiment was a continuation of Lederberg and Tatum’s experiment to find how the transformation of bacteria takes place. The experiment suggested the transfer of genetic material between two bacteria either through direct contact or by transfer of naked DNA molecule.

"This study will concentrate solely on the molecular characterization of seaweed samples collected on Panglao island inSouth-Central Luzon, Philippines. Molecular data will be limited to DNA sequences, with identification relying heavily on Genbank returns via blastN. The researchers would obtain their samples from the generated database and analyze the DNA barcode of each macroalgae. The researchers would also compare the previous list of discovered seaweeds from Panglao island to generate a new and updated version for this study. The research would no text end outside or to the neighboring islands around Panglao, Bohol. Neither would the researchers add or include specimens that did not appear in the database or originate from Panglao island. The data to be considered would also not discuss or include the entire taxonomic key of each available sample."

- please help summary Results Labeling HIV-1 Capsids with a GFP Fluid Phase Marker. To determine whether viral cores in infected cells retained their integrity, we utilized a previously described HIV-1 vector in which GFP was inserted between matrix (MA) and CA (pNL4-3 Gag-iGFP) (35) (Fig. 1A). Proteolytic processing during virion maturation releases GFP from the Gag precursor, some of which remains trapped inside the capsid and is released upon loss of core integrity (Fig. 1B). We also utilized a previously described RNA stem-loop system in which 18 copies of BglG stem loops (BglSLs) were engineered into the HIV-1 genome in place of vif/vpr to facilitate the detection of nascent HIV-1 genomic RNA at the HIV-1 transcription site (Fig. 1A). This system can be used to identify the capsids that lead to productive infection and determine the nuclear location of integration (25). Virions were produced by cotransfection of an HIV-1 vector expressing Gag-iGFP and a vector expressing wild-type…arrow_forwardPart E - Exploring parallel sheet structure and hydrogen bonding patterns A different segment of a 3 sheet found in GFP has two parallel strands.
