give the names of, and draw sketches of, two different bacteriophages that do not contain double-stranded DNA inside their capsid coat.

Homework Answers

Answer #1

Bacteriophages are the viruses that infect bacteria and often makes the bacteria more pathogenic for humans. They mostly contain double stranded DNA, but single stranded DNA (ssDNA) and RNA also exist.

Examples of single stranded DNA phages are M13, X174

M13 belongs to inoviridae which is filamentous and escapes via budding.

X174 is a microviridae with a diameter of 35 nanometers with isometric morphology (icosahedral). It is the first ssDNA sequenced.

Examples of ssRNA phages are: Qb and R17

Qb and R17 hav icosahedral (+) strand

consider the following information. A new prokaryotic organism, Biochemistreus whineous, is found. It has double-stranded DNA for its circular chromosome. Its chromosome contains cytosine, guanine, adenine, and 6-methyluracil, and two other complementary bases chemistry and biology. Its mRNA, tRNA and rRNA look and act just like E. coli with the exception of the two additional bases. It’s replicating DNA polymerase works just like E. coli DNA polymerase. The polymerases that make mRNA, tRNA and rRNA for this organism work just...
