T2.6 Structure of DNA and RNA Flashcards
The three parts of nucleotide
Sugar, Phosphate, Base
Link to a picture
Need to know what it looks like
The sugar of a nucleotide
Ribose (RNA) or Deoxyribose (DNA)
Sometimes called pentose sugar
What is the difference between a deoxyribose and a ribose?
Ribose has an -OH group on the 2’ carbon while deoxyribose only has a -H
Link to picture
cause de-oxygen
Phosphate group
Acidic, negativly charged
has phosphate
link to confusing picture of a phosphate group
idk what else
Nitrogenous base
1 (pyrimidines) or 2 (purines) ring structures
How many hydrogen bonds form between A and T?
2
How many hydrogen bonds between form between C and G
3
What provides the strong and stable backbone of DNA
Alternating sugar and phosphate groups
idk how dont ask me
Differences between DNA and RNA’s pentose sugar
DNA- deoxyribose
RNA - ribose
Differences between DNA and RNA’s strands
DNA - double stranded
RNA - single stranded
Differences between DNA and RNA’s bases
DNA - contains Thymine
RNA - contains Uracil
Can u draw and label a simple diagram of a single strand of nucleotides???
u better
Link to video but add a phosphodiester bond label
and make it a single strand
What is the chain of nucleotides linked by?
Covalent and phosphodiester covalent bonds
Antiparallel
The two strands run in opposite directions. One strand is oriented in the direction of 5’ to 3’ and the other is 3’ to 5’
What is the structure DNA
double helix
