The answer is C - Recombinant DNA. Why?
A transgene is a gene or genetic material that has been transferred naturally, or by any of a number of genetic engineering techniques from one organism to another. The introduction of a transgene (called "transgenesis") has the potential to change the phenotype of an organism.
Answer: The genetic material of the cell is duplicated during S phase of interphase just as it was with mitosis resulting in 46 chromosomes and 92 chromatids during Prophase I and Metaphase I. However, these chromosomes are not arranged in the same way as they were during mitosis.
Explanation:
The correct answer is option D
The places that has most extreme temperatures are desert and tundra.
The Desert region is known for its hot and dry climatic conditions. The temperature there is very high all around the year and the surviving there is a very difficult task. The plants and animals living there has some adaptations that helps them to live in the hot climate.
The Tundra region is known for its cold climate and the plants there is shrubs, herbs and the animals have some adaptations that helps them to live in cold climate.
Answer: Option B is incorrect rest all the statements are correct.
Explanation:
A single trait can be controlled by multiple genes: A single trait can need multiple gene to be controlled. There are many traits in the body which can be controlled by the multiple genes in the body.
A single trait can alter multiple genes: The activity of a single gene can alter the activity of the multiple genes of the body. The faulty protein produced by the gene can also effect the other genes of the body.
A single gene can influence multiple traits: A single gene in the body can affect multiple characters of the body. A single gene can be responsible or eye color, hair color, skin color et cetera.
