Étant donné que les personnes non apparentées ont presque
certainement un nombre différent d'unités de répétition, les DOS
peuvent être utilisées pour faire la distinction entre des personnes
non apparentées. Ces loci STR (emplacements sur un
chromosome) sont ciblés avec des amorces spécifiques à la
séquence et amplifiés par PCR. ... Ainsi l'analyse STR fournit un
excellent outil d'identification.
Answer:
(D) The protein that is first made gets modified afterwards
Explanation:
The first amino acid in any protein in eukaryotes is always methionine (Met). But, in some proteins any amino acid other than methionine may be found at N terminus of a protein. Like in this example, the HBB protein starts with a valine (Val) instead of methionine. It happened because of post-translational modification which includes the action of aminopeptidases which cleave 1 or 2 amino acids from N terminus of a protein as a result of which any amino acid other than methionine may exist at amino terminus.

Answer: Cloudy with Precipitation
Explanation: Winds blow towards the low pressure, and the air rises in the atmosphere where they meet. As the air rises, the water vapor within it condenses, forming clouds and often precipitation.
