DNA's structure is what?

Double helix/twisted ladder

5

Structure of the DNA was determined by whom?

Watson and Crick

6

Basic unit of DNA

Nucleotides

Three types of nucleotides

Deoxyribose sugar
Phosphate group
Nitrogen base

8

What are the nitrogen bases and how do they pair?

Adenine-Thymine
Guanine-Cytosine

9

What do hydrogen bonds do?

Hold together nitrogen bases

10

During what phase of interphase does replication occur?

S

11

What does the ribosome in the cell do?

Makes proteins

12

What does RNA stand for?

Ribonucleic acid

13

What is the form of RNA?

Single stranded

14

What does RNA contain?

Ribose sugar

15

In RNA, what are the four nitrogen bases?

Adenine, uracil, cytosine, guanine

16

What are the three types of RNA?

Messenger (mRNA)
Transfer (tRNA)
Ribosomal (rRNA)

17

What are the two parts to proteins synthesis?

Transcription and translation

18

Where does transcription happen and what is it?

It happens in the nucleus of the cell and it is the process of forming RNA from DNA

19

DNA _____ the _____, while RNA _____ the _____.

Stores the information
Makes the protein

20

What does Helicase do?

Unzips and zips up DNA

21

What is a group of three bases on mRNA that codes for an amino acid?

Codon

22

What makes up amino acids, and what do amino acids make up?

Nucleic acids make up amino acids and amino acids make up proteins

23

Where does translation happen and what is it?

It happens in the ribosome and it is the making of protein from RNA

24

Which form of RNA carries anticodons?

tRNA

25

What is a set of three bases on tRNA that compliments a codon on mRNA?

anticodon

26

What is a peptide?

It holds amino acids together

27

List the 2 steps of the replication process…

DNA unzips
the bases attach to the open strands of DNA
