Consider an acetate buffer, initially at the same pH as its pKa (4.76). When sodium hydroxide (NaOH) is mixed with this buffer, the:

#Section 4: Fundamentals of Biological Engineering

pH rises more than if an equal amount of NaOH is added to an acetate buffer initially at pH 6.76
pH rises more than if an equal amount of NaOH is added to unbuffered water at pH 4.76.
ratio of acetic acid to sodium acetate in the buffer falls.
sodium acetate formed precipitates because it is less soluble than acetic acid.

You are a scientist who is using genomics to currently study a new bacterial species that no one has ever studied before. The following sequence is a piece of DNA within the coding region of a gene that you have recently sequenced.

You are using shotgun sequencing to determine the DNA sequence of the genome of this new bacterial species. For one strand of a 30-nucleotide long stretch of DNA, you get the following sequences out of your shotgun sequencing reaction.

Choose correct 30-nt-long DNA sequence with the help of above-mentioned fragments
