The answer is A. Erwin Chargaff had discovered years earlier that the percentages of adelnine [A] and thymine [T] bases are almost equal in any sample of DNA. It became the Charfaff's Rule. However, no one knew why they did.

Here is a Punnett square <span> that shows a cross between a heterozygous red bull (Rr) and a heterozygous red cow (Rr).
Since the phenotype is unknown, we could say it's short ( RR) (Rr) and long (rr)
Since it's mixed, we could say that the ratio is 3/1</span>
Answer:
B) Pure culture.
Explanation:
Obtaining a pure culture involves culturing the organism on the bacteriologic agar. Initially blood agar is used because it supports the growth of many bacteria and the type of hemolysis can be observed.
In order to obtain pure cultures, following steps are done :
1)The bacteria are normally streak onto solid media.
2) Inoculating loops are used for streaking.
3) Then the plate is incubated at desired temprature.
4) Then after sometimes , colonies are visible wherever <u>a microbial cell capable of growth on particular medium was deposited on the agar surface.</u>
As in the above scenario , a bit of isolated colony is taken and is inoculated in a separate medium thus a pure culture is formed.
Hence option B) Pure culture is the right answer.
