<span>The
DNA is stored cold with the instagene matrix after boiling samples in order to
slow bacterial growth. In that way, you will greatly slow down the activity of
any remaining enzymes that could harm your DNA. Most likely it is a way of
preserving the DNA and to avoid it bacterial contamination.</span>
The answer is sediments because sediments break down and are every where on earth also break down due to weathering
Answer:
ppss and PPSS
Explanation:
Just as indicated in the question above, Flies homozygous for singed and purple were crossed with flies that were homozygous for normal bristles and red eyes.
And a Drosophila mutation called singed (s) causes the bristles to be bent and misshapen.
A mutation called purple (p) causes the fly’s eyes to be purple in color instead of the normal red.
Thus, the genotypes of the parental flies in Cross 1 are
PPSS and ppss
