Zero degrees latitude is the line designating the Equator and divides the Earth into two equal hemispheres (north and south).
Answer:
The correct answer would be
- It cures all cases of cystic fibrosis.
-
It involves the modification of DNA.
- It attempts to replace a mutated gene with normal DNA.
- It does not always cure patients who use it.
Gene therapy is an experimental technique used to treat the genetic disorder by transplanting the normal gene into the cell in order to replace the missing or defective gene in a cell.
It helps in treating genetic disorders such as cystic fibrosis, hemophilia et cetera.
It can be of two types of somatic gene therapy and germline gene therapy.
Answer: it is species!
Explanation: species is a GROUP of individual organisims that inter breed with others!
Answer:
(4) Both (1) & (2)
Explanation:
Viviparous germination is a type of seed germination in which seeds germinates but still attached with the plant body. This type of germination is present in plants such as Sonneratia and Rhizophora. In these plants, the embryo which is present inside the seed grows and break the seed coat and after that, it comes out the fruit which is still attached to the plant.
Answer:
Contains large polytene chromosome that permit visual inspection of genomic events.
Were used to study the genetic effects of mutations.
Were used to establish the concept of chromosomal inheritance.
Explanation:
<em>Drosophila melanogaster </em>is a model organism that is used by scientists to study the genes and effect of a mutation on the genes. Drosophila is used as a model organism as it has a very short life cycle and the offspring can be produced in a short duration of time.
Because of these characteristics, Thomas Hunt Morgan wanted to study the factors of inheritance on the <em>Drosophila</em> and concluded in the form of the chromosomal theory of inheritance by the effect of mutation on genes that lead to linkage mapping.
Also, the salivary gland of fruit fly contains the polytene chromosome which allows us to look into the gene events.
Thus, the selected options are correct.
