N. Brown’s classes
Slide21 Every
nucleotide is made up of…
Sugar
PhosphateNitrogen baseAll of the above
Slide31
Every nucleotide
monomer is
made up of…Ribose SugarPhosphate
Nitrogen baseAll of the above
In
ribonucleotides
of RNA, this C of the ribose is bonded to an H and to an OH group. In
deoxyribonucleotides
of DNA, this C shows 2 H bonded instead---
deoxy
-
means w/o an O!
Slide42 Regarding
the nitrogen bases, Adenine always bonds with which one?
Cytosine
ThymineGuanineUracil
Slide52 Regarding
the nitrogen bases,
in double stranded DNA, the nucleotide Adenine
always bonds with which one?CytosineThymine
GuanineUracil
Note the
antiparallel
(facing opposite directions) strands joined by complementary nitrogenous base pairs between the
deoxyribonucleotides
: A to T and C to G
Hydrogen bonds (H bonds) attract the nitrogenous base pairs to each other and hold the 2 strands of
Dna
together in the double helix
Slide6The 2 halves of the
DNA double helix
are comprised of H bonded complementary, but
anti-parallel, deoxyribonucleotide base pairs.
Slide73
DNA
contains the code to make what macromolecule?
GlucoseProteinCarbohydrates
Lipids
Slide83 DNA
contains the code to make what macromolecule?
Glucose
ProteinCarbohydrates
Lipids
Each gene contains the pattern for a particular protein (the order in which to put amino acid monomers together to build the polymer called a protein.
Proteins are the tools that carry out all the jobs and build most of the structures in our cells.

two strands of DNA are bonded together in the middle by their…
Sugars
Phosphates Nitrogen bases

Deoxyribose
SugarsPhosphates groups
Nitrogenous bases
H
hydrogen
bonds between the complementary base pairs
temporaily
join them the two strands—the Hydrogen bonds are broken to allow DNA replication or transcription when mRNA is made.
Slide125 What type of bonds are between the sugars and phosphates in DNA?
Hydrogen
Covalent
IonicMetallic
Slide135 What
type of bonds are between the sugars & phosphates in DNA?
Hydrogen
CovalentIonicMetallic
Strong permanent covalent bonds link sugars and phosphates into the sides (backbones) of the double helix
