The reason for why a single base change may not change the amino acid has to be explained. Concept Introduction: Inter-relation between DNA, codon, Gene and Genome: DNA is a nucleic acid . The nucleic acid is a polymer of the nucleotides which are monomeric units. The sequence of bases of the nucleotides codes an amino acid. Such a sequence of bases is known as DNA codon . Once the amino acids are coded, a protein that is formed from the amino acids can be found. So, the DNA which codes the protein is known as Gene and the sum total of DNA is known as Genome .

Interpretation Introduction

Interpretation:

The reason for why a single base change may not change the amino acid has to be explained.

Concept Introduction:

Inter-relation between DNA, codon, Gene and Genome:

DNA is a nucleic acid. The nucleic acid is a polymer of the nucleotides which are monomeric units. The sequence of bases of the nucleotides codes an amino acid. Such a sequence of bases is known as DNA codon. Once the amino acids are coded, a protein that is formed from the amino acids can be found. So, the DNA which codes the protein is known as Gene and the sum total of DNA is known as Genome.

(a 4 shows scanning electron microscope (SEM) images of extruded actions of packing bed for two capillary columns of different diameters, al 750 (bottom image) and b) 30-μm-i.d. Both columns are packed with the same stationary phase, spherical particles with 1-um diameter. A) When the columns were prepared, the figure shows that the column with the larger diameter has more packing irregularities. Explain this observation. B) Predict what affect this should have on band broadening and discuss your prediction using the van Deemter terms. C) Does this figure support your explanations in application question 33? Explain why or why not and make any changes in your answers in light of this figure. Figure 4 SEM images of sections of packed columns for a) 750 and b) 30-um-i.d. capillary columns.³

fcrip = ↓ bandwidth Il temp 32. What impact (increase, decrease, or no change) does each of the following conditions have on the individual components of the van Deemter equation and consequently, band broadening? Increase temperature Longer column Using a gas mobile phase instead of liquid Smaller particle stationary phase Multiple Paths Diffusion Mass Transfer
