Answer:
2
Explanation:
Number of different nucleotides available = 10
If a codon would consist 2 nucleotides, possible combination of amino acids would be = 10 * 10 = 100
Proteins found in this region have 76 different types of amino acids which is less than the possible 100 amino acids. So, 2 nucleotides per codon should be enough to produce all the amino acids.
Hence, the smallest possible codons in the genetic code of these alien cells would contain 2 nucleotide letters per codon.

Answer;
-Cell division
Explanation;
-Glandular epithelium forms the covering of all major glands. It is also present in the intestinal lining.
-Cells are regenerated by division in the basal layer and migrate toward the apical surface to replace cells lost by fragmentation. Cell division is indicated by the mitotic phase cells located in the deepest (basal) layer of the glandular epithelium.
