1

How many codons do you need for one amino acid

Three

2

Codon

A sequence of three on an RNA strand

3

Replication

Copying of nucleic acid (DNA)

4

Translation

mRNA codons are interpreted by ribosomes. Amino acid codons compliment mRNA codons

5

What is the enzyme called that unzips DNA?

RNA polymerase

6

What is the codon? What is the anti-codon

Codon: mRNA
Anti-codon: Amino acid
example: AAA (mRNA) UUU (Amino acids)

7

What is the job of RNA

To create proteins

8

What are the differences between DNA and RNA

DNA: Sugar is deoxyribose, double stranded, and A w/ T; G w/ C
RNA: Sugar is ribose, single stranded, Thymine is replaced with uracil, A w/ U; G w/ C

9

What type of strands do RNA and DNA have

RNA: single stranded
DNA: Double stranded

10

Instead of the base pair "A and T", what replaces what in RNA

"U" replaces "T"

11

what does RNA stand for

ribonucleic acid

12

DNA makes protein (True or false)

False. RNA creates proteins

13

Transcription

-Created in nucleus
-RNA polymerase binds to DNA and opens DNA into separates strands
-RNA polymerase uses one DNA strand to assemble the RNA molecule
-Thymine is replaced with uracil
- RNA BEING BUILT

14

Since DNA can't make proteins, what happens instead?

The instructions from the DNA are copied to be changed into RNA

15

What are the three types of RNA and what is theyre purpose?

-Messenger RNA: Carries copies of the DNA's instructions to the rest of the cell.
-Ribosome RNA: Makes up ribosomes, along with protein
-Transfer RNA: Uses mRNA to transfer amino acids from the cytoplasm to the ribosomes

16

Gene

The coded instructions on a DNA strand, controls production of protein. (3 bases on each strand with six total)

17

Protein Synthesis

The making of protein

18

Amino Acid
