RNA

Question 1

RNA stands for

Answer 1

Ribonucleic acid

Question 2

Name 5 differences between DNA and RNA

Answer 2

RNA is
1) single stranded
2) contains the sugar RIBOSE instead of deoxyribose
3) contains the nitrogen base URACIL instead of thymine (pairs with adenine )
4) RNA can leave the nucleus with DNA’s instructions
5) 3 types : mRNA, rRNA, tRNA

Question 3

What are the three types of RNA ?

Answer 3

1) messenger RNA (mRNA)
2) ribosomal RNA (rRNA)
3) transfer RNA (tRNA)

Question 4

Which type of RNA …
copies instructions (nitrogen base sequence ) from DNA in nucleus and delivers them to the ribosomes

Answer 4

Messenger RNA (mRNA)

Question 5

Which type of RNA …
Makes up the structure of the ribosome (remember ribosomes aren’t membrane bound like other organelles !)

Answer 5

Ribosomal RNA (rRNA)

Question 6

Which type of RNA …
delivers the necessary amino acids to the ribosomes for protein assembly.

Answer 6

Transfer RNA (tRNA)

Question 7

Codon are 3 nitrogen bases on

Answer 7

mRNA

Question 8

Anticodon are 3 nitrogen bases on

Answer 8

tRNA
