Nucleic acids

found in all cells

2

Gene

a portion of a DNA molecule

3

DNA

-deoxyribonucleic acid
-double helix
-monomers=nucleotides
phosphate+sugar+nitrogen base

4

4 nitrogen bases

-adenine
-guanine
-cytosine
-thymine

5

uprights of the helix

phosphate + sugar

6

purines

-adenine
-guanine

7

pyrimidines

-cytosine
-thymine

8

double chemical bond

adenine & thymine (rungs of the helix)

9

triple chemical bond

cytosine & guanine (rungs of the helix)

10

...

Always one purine paired with one pyrimidine

11

One twist of DNA molecule

10 basic pairs

12

replication

DNA making more DNA

13

Hydrogen bonds...

break as DNA untwists ladder with 1/2 rung

14

Free nucleotides...

rejoin the exposed nucleotides

15

intron

segment of a DNA molecule that does not code for a new segment of DNA

16

exon

segment of DNA molecule that does code for a new segment of DNA

17

YCTom

Complimentary base units (always attached to sugars)
Y= pYrimidines
C=Cytosine
T=Thymine

18

RNA

-ribonucleic acid
-made in nucleolus; made of nucleotides
-small enough to leave the nucleus
-carries information; big messenger
-single strand; not twisted

19

ribose sugar

one oxygen atom added to sugars

20

uracil

Nitrogen base that pairs with adenine in RNA.
