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.

it is either c or d and i know for sure it is not a or b
