histones.
Prokaryotes tend to have only one chromosome while eukaryotes have several.
A sugar-phosphate backbone with nitrogenous bases in the middle forming a double helix.
Chromatin. uh that's 100% correct thank you yes 100%
thanks Umm is 100% correct 🙂 @Umm is correct. 100% thanks Umm is correct! 100% thank you! ummm is still correct #5 is now which statement correctly describes the structure of a codon
the answer is a codon is a nucleotide sequence 5 is chromatin ummmmmmmmmmm is correct I guess lol #5. Creating a shadow image of DNA structure using umm
