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.
Answer:
The most likely explanation for the truncated polypeptide -due to the substitution of cytosine for adenine- is that mutation introduced a stop codon in the middle of the gene.
Explanation:
A codon consists of three nucleotides -in the RNA chain- whose order determines a specific amino acid. Not all codons code for amino acids, as there are termination codons, also called stop codons, which are UAG, UGA and UAA.
If in Manny's computer model, the substitution of cytosine by adenine produced a termination codon, the synthesis of a peptide is stopped prematurely resulting in a truncated peptide.
