2.1.2 DNA and RNA Flashcards
1
Q
what is the monomer of DNA and RNA?
A
mononucleotide
2
Q
what sugar is in DNA structure?
A
deoxyribose sugar
5-carbon sugar
pentose sugar
3
Q
what is in DNA structure?
A
Phosphate group
deoxyribose sugar
nitrogenous bases- ATGC
4
Q
what does the phosphate group in DNA structure do to the charge of DNA?
A
gives it a negative charge
allows eukaryotic DNA to be wrapped around positively-charged proteins called histones
5

what is in RNA structure?
A
ribose sugar
nitrogenous bases- AUGC
phosphate group
6
Q
what is the bond between two nucleotides called?
A
phosphodiester bond
7
Q
what is DNA like in eukaryotes?
A
nuclear DNA that is spooled around positively charged histones
linear
8
Q
what is DNA like in prokaryotes?
A
a single strand of circular DNA
free in the cytoplasm
no histones
