Flashcards in Nucleotides & Nucleic Acids Definitions Deck (19):
1

Nucleotide

A molecule containing a:
-Pentose ring
-Purine or pyrimidine base
-One to three phosphates

2

Ribonucleic Acid (RNA)

Contains hydroxyl group

3

Nucleic Acid

Nucleotides connected by phosphodiester bonds

4

Deoxyribonucleic Acid (DNA)

Lacks hydroxyl group

5

Tertiary Structure

Double Helix

6

Quaternary Structure

Strands and Proteins create complex structures

7

Adenine

DNA Base (Purine)

8

Thymine

DNA Base (Pyrimidine)

9

Transcription

DNA to RNA

10

Uracil

Only found in RNA (Pyrimidine)

11

Guanine

DNA Base (Purine)

12

Cytosine

DNA Base (pyrimidine)

13

Double Helix

Tertiary structure of DNA
Double helix is cause by H bonds between bases

14

Anti-parallel

DNA Strands run Anti-parallel to each other

15

Palindrome

Same backwards and forwatds, refers to nucleotide sequencing in DNA & RNA

16

Histone

Any group of basic proteins found in chromatin

17

Nucleosome

DNA Interacts with histones and forms NUCLEOSOMES

18

Chromosome

Contains genetic info

19

Explain some of the - Similarities and differences between RNA and DNA

-RNA contains Hydroxyl group making it more reactive than DNA
- DNA found in Nucleus
- RNA found throughout cell
