Question

question 20
individual human genetic information is:
o unique for each individual and no one in human history has had the exact same sequence of genes, unless there are identical twins
o a single stranded shape
o somewhat unique for individuals because past human ancestors have the exact same sequence of genes as their relatives
o a triple helix shape

Explanation:

Human genetic information is encoded in DNA which has a double - helix structure. Each individual's genetic sequence is unique, except for identical twins who develop from a single fertilized egg and thus have the same genetic material. Past human ancestors do not have the exact same gene sequence as their distant relatives.

Answer:

unique for each individual and no one in human history has had the exact same sequence of genes, unless there are identical twins
