List the 4 bases of DNA and which bases bind together

Adenine binds with thymine, cytosine bonds with guanine

1

List the 4 bases of RNA. Which bases bind together

Adenine binds with uracil, cytosine bonds with guanine

2

What is the sugar in DNA

Deoxyribose

3

What is the sugar in RNA

Ribose

4

List the purines, describe their structure

Adenine and guanine, 2 rings

5

List the pyrimindines describe their structure

Cytosine and thymine, 1 ring

6

List the three differences between DNA and RNA

DNA is double stranded, RNA is single stranded, DNA has thymine, RNA has uracil, DNA=replication! RNA=transcription, 1 form of DNA, 3 forms of RNA (mRNA, tRNA, rRNA,) DNA -found only in nucleus, RNA -found in nucleus, cytoplasm, ribosome,

7

List the complete names of RNA and describe each RNA function, which is most abundant

Messenger RNA :carries DNA information to the ribosomes, ribosomal RNA : makes up the ribosome, transfer RNA : carries amino acids to the ribosomes where the amino acids join to make a protein, most abundant: rRNA

8

Where would you find DNA in the cell

In the nucleus

9

Where would you find mRNA in the cell

In the nucleus, cytoplasm, and ribosome

10

Where would you find tRNA in the cell

The ribosome

11

Where are proteins made

The ribosomes

12

What is the process called that makes RNA from DNA

RNA synthesis, transcription

13

What enzymes add the bases during replication

DNA polymerases

14

What enzyme unwinds the double helix before replication can occur

Helicases

15

What does DNA stand for

Deoxyribonucleic acid

16

What does ribonucleic acid stand for

Ribonucleic acid

17

What part of the cell does tRNA get the amino acids from

The cytoplasm

18

What carries the DNA code from the nucleus to the ribosomes

mRNA

19

How many strands does DNA have, RNA

2,1

20

Who developed the model for DNA

James Watson and Francis crick

21

Who did DNA research during X-rays what information did they learn about DNA

Rosalind Franklin , DNA is twisted, molecules are arranged at regular intervals

22

DNA and RNA are both _acids

Nucleic

23

The bases of DNA are held together by weak _bonds

Hydrogen bonds

24

What are the building blocks of DNA

Nucleotides

25

What is the sequence of 3 nucleotides of tRNA called

Anticodon

26

What is the sequence of 3 nucleotides of mRNA called

27

Where does replication occur

In the nucleus, during s phase of interphase

28

Where does translation occur

Ribosome

29

Where does transcription occur

The cells nucleus
