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.
DNA polymerase / DNAP. DNA polymerase (DNAP) is a type of enzyme that is responsible for forming new copies of DNA, in the form of nucleic acid molecules. Nucleic acids are polymers, which are large molecules made up of smaller, repeating units that are chemically connected to one another.NA polymerase / DNAP.
