RNA and Ribosomes (Biology 013)

Question 1

What is the difference between DNA and RNA

Answer 1

Deoxy is not present in RNA, RNA has uracil instead of thymine, RNA is single stranded, RNA is smaller than DNA and less stable

Question 2

What is the enzyme that is responsible for unzipping the DNA strand and adds RNA nucleotides

Answer 2

RNA polymerase

Question 3

What are the three types of RNA

Answer 3

mRNA, tRNA and rRNA

Question 4

What is the purpose of mRNA

Answer 4

Carries genetic information from DNA to ribosome

Question 5

What is a group of three bases in mRNA

Answer 5

Codon

Question 6

What is the purpose of tRNA

Answer 6

Carries the appropriate amino acid for translation, binds with mRNA in the ribosome

Question 7

What is a group of three bases in tRNA

Answer 7

Anticodons

Question 8

What is the purpose of rRNA

Answer 8

Connects amino acids together in ribosomes, makes up part of the structure of ribosomes

Question 9

What is a ribosome

Answer 9

A small structure that is found in all cells, site of protein synthesis
