Question 1

Know the structural differences between DNA & RNA

Answer 1

DNA = Double Stranded, Deoxyribose sugar 
RNA= Single Stranded, Ribose sugar

Question 2

Be able to tell the difference between DNA sequence & RNA sequence

Answer 2

DNA= ATGC ( Adenine, Thymine, Guanine, Cytosine)
RNA= Adenine, Uracil, Guanine, Cytosine

Question 3

Know which bases are complementary:

Answer 3

A-T
G-C
A-T

Question 4

Know the three components of a nucleotide:

Sugar, Phosphate, Nitrogenous Base

Answer 4

DNA= Deoxyribose, Po4^3-, THYMINE

RNA= Ribose sugar, Uracil

Question 5

DNA REPLICATION

• Def.
• Occurs?
• Makes?

Answer 5

• The process the CELL uses to copy its own DNA
• Occurs in S-phase of cell cycle
• Make identical sister chromatids

Question 6

Transcription

Answer 6

DNA TEMPLATE is used to make a strand of RNA

Question 7

Where does Transcription Occur

Answer 7

NUCLEUS

Question 8

TRANSLATION

Answer 8

MRA is use to make a protein

Question 9

TRANSLATION OCCURS

Answer 9

Happens in RIBOSOME (CYTOPLASM OR RER)

Question 10

Where can DNA, MRNA, TRNA be found in the Cell?

Answer 10

DNA= Nucleus 
tRNA= Cytoplasm
mRNA= Cytoplasm

Question 11

Function of the DNA

Answer 11

Stores genetic information

Question 12

Function of mRNA

CARRIES

Answer 12

Carries messages from the NUCLEUS to the Cytoplasm

Question 13

Function of tRNA

READ

Answer 13

READ messages of NUCLEIC ACID or NUCLEOTIDE and TRANSLATES them into PROTEIN
