<span>the virus injects the genetic info. this can be RNA or DNA. retroviruses inject RNA. after injection, the host cell transcription/translation machinery is hijacked and starts making virus proteins from the viral genes.</span>
Answer: 20%
Explanation:
Recall that the sum of all nitrogenous bases is equal to 100%.
Hence: A + C + G + T = 100%
Now, since adenine nucleotides is 30%, then thymine is 30% as well (A = T). Thus, the total of both is 60%.
From 100 remains 40% which is divided equally between guanine and cytosine, so each is 20%.
Thus, the percentage of the same DNA molecule that would be expected to be guanine nucleotides is 20%
There are two main types of research, which could be classified as manipulation and observation. Both types are fundamental in research.
<h3>Empirical research and evolution</h3>
Evolution is the subdiscipline in biology that studies how organisms change to adapt to challenging environmental conditions.
Empirical research refers to any scientific investigation in which conclusions are drawn from empirical evidence.
This type of research (empirical research) is based on observation of the natural world and experimental procedures.

Answer:
The parent with black fur had genotype Bb.
Explanation:
White fur is recessive in mice, so a mouse with white fur has to have two alleles of the white fur gene (bb). Black fur is dominant to white fur, so a mouse with black fur only needs one allele of the black fur gene (BB or Bb). In order for a black mouse and a white mouse to produce white offspring, the black parent has to have an allele for the white fur gene (Bb).
