What are insulators? dna sequences that block the effect of enhancers in a position‑independent manner dna sequences that block the effect of enhancers in an orientation‑dependent manner dna sequences that block the effect of enhancers in a position‑dependent manner proteins that block the effect of enhancers in a position‑dependent manner proteins that enhance the effect of enhancers in a position‑dependent manner

DNA sequences that block the effect of enhancers in a position‑dependent manner

Explanation:

In one word

It is a sequence of DNA that inhibits enhancers (a regulatory elements)

in a position dependent manner

nucleic acid molecules are incredibly complex, containing the code that guarantees the four different nucleotide units comprise dna, the nucleic acid of interest to the genealogist. and one of four nitrogen-containing molecules called nucleotides

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
