Summary Introduction

To explain: The changes that can occur at each position without altering the encoded amino acid residue of 5ʹ–AUGAUAUUGCUAUCUUGGACU.

Introduction:

Mutation is the alteration in the sequence of the nucleotide of genome of extrachromosomal DNA, virus or an organism. Mutations can be insertion, deletion or substitution of one or more nucleotide base. In substitution mutation, single nucleotide is exchanged for another nucleotide.

Synonymous substitution involves substitution of one base with another in the coding region of gene. The amino acid formed after this type of mutation remains same if the substitution takes place at the third position of codon. This is because of the degeneracy of codons.

9) Below, there is a representation of an SDS-PAGE gel. Assuming the samples in the MW standard have masses of: 66 kDa, 45 kDa, 36 kDa, 29 kDa, 24 kDa, 20.1 kDa, and 14.2 kDa, a) Figure 4: indicate where each of the measurements were taken and label as in II.6. figure 2 above. b) As in II.7. Table 1 above create Table 2 using the data below. Determine the r.f. values for the MW standards, plot the relative mobility versus the log of the mass for the standards, and use the best fit straight line to determine the molecular weights of the proteins in the whey, peak 1, and peak 2 lanes.

what are the different classes and some examples of neuroprotectants that can be used to treat, prevent, or combat neurotoxicity/a neurotoxicant...for example, antioxidants, nutraceuticals, etc.,..?
Imagine that aldolase can react with the seven carbon molecule Sedoheptulose-1,7-bisphosphate (below). Use the mechanism to predict the two products generated. Please draw out the stereochemistry in a fischer projection.
