umm is 100% correct thanks
yep 100%
thanks
Umm is correct 100% :)
@Umm is correct. 100%
if ur last question is
Chromosomes in eukaryotes are made of DNA wrapped around proteins. What is the combination of DNA and protein called?
the answer is NUCLEOSOMES
thanks Umm is correct!
100% thanks!
ummm is correct still
#5 is now which statement correctly describes the structure of a codon
the answer is A codon is a sequence of nucleotides
