Explanation / Answer
1. All blood cells are formed by multipotent stem cells of bone marrow. Thus option B is correct.
2.) The organism whose genetic material is modified or it contains genes from other species by genetic engineering is called transgenic organism. Thus they contain a foreign gene and option A ) is correct.
3). As explained above transgenic organization contain a foreign gene inserted in them. Thus option C) is correct.
4). Transcription is conversion of DNA to form a copy of RNA. Thus option B) is correct.
