It's mainly because your arteries pump a lot of blood so a few things could happen, you could tear the artery or the needle could pop out, they're usually harder to get to, and it's just very dangerous.

Answer:

DNA is copied and transcribed into another form. This smaller segment is made of <em><u>genes.</u></em>

Explanation:

Cell growth, replication, and cell repair are controlled by genetic material found within DNA molecules. These deoxyribonucleic acids' long-chain helical macromolecules are assembled from complex sequences called nucleotides; strong covalent bonds attach these four monomers (adenine, cytosine, guanine, thymine).

Coding regions of DNA are called genes- they contain specific instructions for the cell. Genes can include multiple nucleotides and even several chromosomes. Gene expression typically includes transcription into RNA, and translation into amino acids/ proteins.
