Which characteristics describe the human genetic code? check all that apply.
1. contains over 3 billion base pairs
2. can only understand human genetics
3. can explain genetic diseases
4. composed of 50,000 genes
5. composed of 23 chromosomes

the correct statements are:

the entire length of the human genome is about 3 billion base pairs.

it is divided into 23 pairs of chromosomes that are, 46 chromosomes. 22 pairs are termed as autosomes and 1 pair termed as sex chromosomes (x and y chromosome).  

the study of the human genome can us understand human genetics, genetics of related species as well, and mechanism of certain diseases.

identify the dna change shown in the diagram and explain how that change can result in the increased genetic diversity often seen among siblings.
