PLEASE SHOW WORK!!!!

T C C 3. (2 pts) The DNA of bacteriophage genomes are either single- or double-stranded. The base composition of eight bacteriophage DNAs are shown in the table below. BASE COMPOSITION Phage A G Pf3 19.8% 24.1% 34.8% 21.3% P4 25.2% 24.8% 25.2% 24.8% 31.8% 18.2% 31.8% 18.2% Ike 25.1% 21.6% 34.3% 18.9% PZA 30.2% 19.8% 30.2% 19.8% s13 23.9% 23.3% 31.7% 21.1% 24.6% 20.75% 34.5% 20.2% Cp-1 30.6% 19.4% 30.6% 19.4% fd Which of these bacteriophage most likely contain single-stranded DNA within the virus? HOW DID YOU! REACH THIS CONCLUSION???? EXPLAIN. What is the name of the rule being applied to address this question (it is based on the name of the scientist that first described the base composition of DNA).

Explanation / Answer

Q.3

a.)

Single Stranded DNA Virus -

Pf3

Ike

S13

Fd

Double stranded dna has equal proportion of Adenine and Thymine, Gunaine and Cytosine due to complemet base pairing. Whereas in single stranded DNA there is no complement base pair, as a result of which equal proportion is not observed in SSDNA.

b.)

Chargaff's rule of base equivalency.
