Question $26(2$ points$)$

Listen

You were running a gel and observed no bands in all lanes other than the DNA ladder lane. You go back to the nanodrop to check your DNA purity data. The following is observed:

DNA concentration:$178$ng$/$ul

$A260$: $3\mathrm{.}234$

$A280$: $2\mathrm{.}058$

$\frac{260}{280}$: $1\mathrm{.}75$

$\frac{260}{230}$: $0\mathrm{.}71$

From the data above you can assume that:

a$)$ The DNA concentration is too low.

b$)$ There were organics remaining in the sample.

c$)$ The DNA concentration is too high

d$)$ There were excess RNA$/$proteins remaining in the sample.

e$)$ The DNA was degraded.
