Answer:
In order to produce human insulin in a bacterium you need to isolate the mature mRNA (after the excision of the introns), produce a DNA copy using the enzyme retrotranscriptase, clone the gene in an expression vector and transform bacterial cells with this genetic construct to produce the insulin.
Explanation:
Eukaryotic cells perform a process called splicing, in which introns (the non-coding fragments of the gene). are excised from the mRNA Prokaryotic cells (i.e. bacteria) don’t perform this process. So, in order to produce a recombinant protein in a bacterium, insulin in this case, the best strategy should be to produce a complementary DNA (cDNA) of the mature mRNA (AFTER the splicing process, the excising of the introns).
Answer:
Mammalian dentition is characterized by heterodonty, in which both the upper and lower teeth are differentiated morphologically into four types: flat, chisel-shaped incisors, conical canines, bicuspid premolars and multicuspid molars in the mesiodistal direction.
Explanation:.
- <u>The mesiodistal crown:</u>dimension is the smallest of any maxillary teeth.The mesiodistal measurement of the pulp chamber is wider compared to the labiopalatal one. The periphery of the socket often dips down palatally, labially, mesially and distally to accommodate the shape of the root.
- <u>Maxillary central incisor:</u>The general shape is similar to maxillary central incisor except that they are shorter and narrower. It has the most cervically located contact area of any incisor. The mesioincisal and distoincisal angles are more rounded than the corresponding angles of maxillary central incisor.
- <u>Permanent mandibular central incisor:</u>The crown dimensions are the smallest of any tooth, it has bilaterally symmetrical crown, and the line angles are the sharpest of any tooth.It shows the shallowest labial developmental grooves, smoothest lingual surface contour and the least developed cingulum.
