RNA

Question 1

Types of RNA

Answer 1

• tRNA = transfer RNA
• mRNA= messenger RNA
• rRNA = ribosomal RNA

Question 2

Function of m RNA

Answer 2

• created in the nucleus
• leaves the nucleus to carry copy of genetic code of one gene to a ribosome in the cytoplasm

Question 3

Features of mRNA

Answer 3

• short
• short lived
• single stranded
• carry out function quickly before being break down by enzymes
• codons in the sequence code for specific amino acids

Question 4

Functions of tRNA

Answer 4

• attach to amino acids, transfer to ribosomes to create polypeptide chain
• codons of mRNA complementary to anticodons of tRNA

Question 5

Functions of rRNA

Answer 5

• makes up the bulk of ribosomes
• combines with protein to make ribosomes
