The correct answer is C) the fluorescent cells can help track the movement of cells.

Explanation:

In the last years, geneticists and scientists created animals that glow in the dark by inserting a Green Fluorescent Protein or GFP gene found in some species of jellyfish. This protein was used in animals such as rabbits, rats, and even chickens. One of the key reasons for this is that by inserting fluorescence scientists can better observe the development and movement of cells. This includes analyzing cells reproduction and growing in embryos of "glowing" animals or inserting the protein in specific cells or organs in an organism to observe how these change or move. Thus, the purpose of studying fluorescent rabbits is that "the fluorescent cells can help track the movement of cells".

In humans, a type of blindness is due to a dominant allele; normal vision is the result of a recessive allele. Migraine headache
yan [13]

Answer:

Yes.

Probability of such child = 1/2 or 50%

Explanation:

According to the question, below are the genotypes and phenotypes possibilities:

aa = normal vision & no headache

Aa = normal vision & no headache

AA = blindness & headache

                                                                      Male                       Female

                                                                        Aa                            aa

Possible genotypes of progeny:            Aa        Aa           aa         aa

So it is clear that out of the 4 probable children, 2 with 'genotype aa' will have normal vision & no headache.

Mathematical expression is as under:

2/4 = 1/2 that means 50% progeny.

The DNA of a prokaryote is arranged in a single coiled chromosome located in a region called the ____________ . Some prokaryotes
Varvara68 [4.7K]

Answer:

1. Nucleoid

2. Plasmid

Explanation:

Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.

However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.
