When comparing maxillary and mandibular lateral incisors the mandibular incisor crown is wider mesio-distally than the mandibula

Viefleur [7K]

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:.

The mesiodistal crown: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.

Maxillary central incisor: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.

Permanent mandibular central incisor: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.

Replication is called semiconservative because half of the strand is

photoshop1234 [79]

Answer: Replication is called semiconservative because each of the original strand is is used as a template for the synthesis of a new strand

Explanation: DNA is a double-stranded helix containing two antiparallel strands that are complementary to each other.

Replication is the process of making identical copies of a DNA molecule. Before replication begins, the double-stranded DNA is first unwound by helicase so that each strand will serve as a template for new strand synthesis.

DNA replication is semiconservative because each DNA strand serves as a template for the synthesis of a new strand, producing two new DNA molecules each one with one new strand and one strand.

Saved and used in the new strand
