EXAM-Biology Ch.10: Nucleic Acids&Protein Synthesis

Question 0

What is molecule of DNA made of?

Answer 0

Deoxyribose sugar
Nitrogenous base (A, T, C, G)

Question 1

What is the primary function of DNA?

Answer 1

To store & transmit genetic information

Question 2

What is DNA named for?

Answer 2

Deoxyribose sugar

Question 3

Who are Watson and Crick?

Answer 3

Discovered the structure of DNA (double helix)

Question 4

What are the bases in DNA? RNA?

Answer 4

DNA- A,T,C,G

RNA- A,U,C,G

Question 5

How do the bases pair up?

Answer 5

DNA- A➡T, G➡C

RNA- A➡U, G➡C

Question 6

What are the differences between DNA and RNA?

Answer 6

DNA- 2 strands, deoxyribose

RNA- 1 strand, ribose

Question 7

What is the function of the types of RNA (tRNA, mRNA, rRNA)?

Answer 7

1) tRNA-brings correct amino acids to ribosome
2) mRNA-takes info. from DNA out of autosomes
3) rRNA- what ribosomes are made of

Question 8

What happens during transcription?

Answer 8

DNA is copied into a strand of mRNA

Question 9

What happens during translation?

Answer 9

The mRNA is read by the ribosome. The tRNA matches amino acids to the codon on mRNA to make a protein.
