particular protein

When the body needs a(n) ________, a the specifically coded part of the DNA is activated.

Histone

________: a protein molecule around which DNA is wrapped for safeguarding and compression.

Nucleoid

________: region that contains looped DNA.

DNA

________ carries genetic info on how to create proteins the body needs.

Eukaryotes

________: stored in nucleus.

Prokaryotes

________: stored in cytosol.

nucleotide sequence
