Features of thanatophoric dysplasia include macrocephaly, narrow bell-shaped thorax, normal trunk length, and severe shortening of the limbs. Other features of this condition include a narrow chest, short ribs, underdeveloped lungs, and an enlarged head with a large forehead and prominent, wide-spaced eyes. Most affected infants die of respiratory failure shortly after birth.
7.2 .2 Explain the process of DNA replication in prokaryotes, including the role of enzymes (helicase, DNA polymerase, RNA primase and DNA ligase), Okazaki fragments and deoxynucleoside triphosphates. The explanation of Okazaki fragments in relation to the direction of DNA polymerase III action is required.
RNA polymerase is the core enzyme in transcription which needs proteins known as transcription factors to bind to the DNA promoter. also DNA plymerase...can't remember what about it though. DNA polymerase isn't involved in DNA transcription.However, DNA polymerase IS involved in DNA REPLICATION.NA polymerase is the core enzyme in transcription which needs proteins known as transcription factors to bind to the DNA promoter. also DNA plymerase... can't remember what about it though.
