Which of the following statements is true regarding covalent bonding in molecules?

The following is an excerpt from a recent scientific publication:“From a chemical point of view, proteins are by far the most structurally complex… structure and chemistry… developed and fine‑tuned over billions of years… location of each amino acid… determines its three‑dimensional shape…. precise shape … determines function.” What evolutionary rationale underlies protein structure–function specificity?

The general structure of an ester functional group is:

Which amino acid side chain is the typical nucleophile in the catalytic triad of chymotrypsin?

Which detailed mechanistic sequence is most consistent with chymotrypsin’s catalytic cycle during peptide bond hydrolysis?

The functional group –OH bonded to a saturated carbon atom is known as:

We used a column to purify our GFP protein. The image of a column below shows a step in our column purification. During this step, a ____________ buffer is being run through the column and _____________ are being eluted off the column (removed from the column).

In the CRISPR-Cas9 experiment, the presence of white E coli on our IPTG/Xgal plates indicated that we had successfully knocked out LacZ function through gene editing.

What percentage of the soybeans produced in the US during 2015 was genetically modified?

In our protein purification lab, what method was used to separate green fluorescent protein (GFP) from other bacterial proteins and molecules?
