A double-stranded piece of alien nucleic acid has been isolated. Each individual strand of the nucleic acid is 160 nucleotides l

ong; for a total of 320 nucleotides in the isolated piece of nucleic acid. An initial analysis shows that of the 320 nucleotides, 95 contain the base uracil.1. How many nucleotides containing the base isoAdenine (iA) would be found in the isolated piece of double-stranded nucleic acid?a. 0b. 95c. 190d. 225e. cannot be determined2. How many nucleotides in the piece of alien DNA would contain the base adenine?a. 40b. 70c. 95d. 140e. cannot be determined

Answer:

95 isoadenine bases;  adenine bases cannot be determined

Explanation:

In Alien DNA;

  • iA  complementary with U
  • iT  complementary with A
  • bG complementary with iC
  1. So if there were 95 nucleotide that contain the uracil then there should also be 95 isoadenine.
  2. Adenine binds with isothymine in alien DNA and there are no information of  isothymine or other bG/iC bases is given, so we cannot determine the adenine bases.

Paul [167]
 <span>A law is a theory that has explained a number of observed phenomena, and it has predicted a number of other phenomena which may as yet be unobserved.  

In that sense, a law is a theory that has not yet been proven wrong or given rise to any contradictions. 

A theory is just a theory until it has been proven true by experiments and observation</span>

But the DNA in the woman's eggs is still perfectly normal. So she won't pass on her lung cancer to her kids. This is why cancer is so rarely inherited. Since cancer often happens because of a DNA accident in a cell other than an egg or a sperm, it is not passed down

Sphinxa [80]

Answer:

incomplete dominance.

Explanation:

According to my research on studies conducted by various geneticists, I can say that based on the information provided within the question this is an example of incomplete dominance. This refers to partial inheritance of one allele for a certain trait which causes the formation of a third phenotype that triggers a physical trait that results in the combination of both alleles phenotype's.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
