RNA

Question 1

Where is RNA made? What is it made by?

Answer 1

• RNA is made in the nucleus by DNA

Question 2

What does RNA stand for?

Answer 2

Ribonucleic acid

Question 3

What is RNA involved in?

Answer 3

• protein synthesis

Question 4

What is the structure of RNA?

Answer 4

• RNA is also a polymer made up of nucleotides, but it differs in structure from DNA

Question 5

How does RNA differ in structure from DNA?

Answer 5

• it consists of a single strand
• the strand is much shorter than that of DNA
• the sugar is ribose, NOT deoxyribose
• it has 3 bases in common with DNA, but a base called uracil replaces thymine

Question 6

What is the function of RNA?

Answer 6

• carries instructions from DNA in the nucleus to the ribosomes in the cytoplasm of a cell
  -> where it controls the synthesis of proteins from amino acids

Question 7

What are the similarities between DNA and RNA?

Answer 7

1. DNA and RNA are both made up of:
   - polymers
   - nucleotides that are made up of a sugar (ribose), phosphate and nitrogen base
   - 4 nitrogenous bases
2. They are both responsible for the synthesis of proteins
