1 Biology I DNA- unit 5

2 Mating two living things breeding

3 The DNA message Depends on the order of the: Nitrogen bases

4 A change in DNA code mutation

5 An exact copy of a living thing clone

6 A chemical that acts as a messenger for DNA RNA

7 Formed from the same fertilized egg twins

8 Type of DNA that results from gene splicing recombinant

9 Energy given off by atoms radiation

10 Breeding to bring out the best characteristics of both parents selective

11 Chemical that controls traits DNA

12 Process by which DNA copies itself Replication

13 A section of DNA with bases TAAGCG will line up with what bases? ATTCGC

14 Recombinant DNA is used in making insulin

15 DNA makes up a part of chromosomes

16 What are the cell parts where protein is made? Ribosomes

17 A short section of DNA that codes for a trait is a: Gene

18 The messages of the genes of the chromosome are carried to ribosomes by RNA

19 True / False. In DNA A always joins with C. False

20 Uracil is found only in (DNA or RNA) RNA

21 If twins result from one egg fertilized by one sperm, they are : Identical

22 T/F. A mutation may occur when DNA copies itself True

23 T/F? Mutations may cause harmful traits to appear. True

24 When DNA transcribes RNA, what RNA base lines up with the DNA base “A” or adenine U, uracil. RNA has uracil instead of thyamine “T”.

25 T/F? DNA is found in cytoplasm. False. DNA is in the nucleus

26 Crossing two species of dog to get a faster more efficient tracker is an example of: Breeding

27 DNA forms the code for the making of : Proteins

28 What are two ways in which a mutation might occur? 1) radiation, 2) some chemicals, or 3) mistakes when DNA is copied

29 T/F? Cloning can result in a new kind of plant or animal. False. A new kind of plant or animal would be the result of a mutation that is passed on

30 How can DNA be used to arrest and convict a person guilty of violent crimes? Blood, hair, or sperm cells can be collected from the crime scene. They all contain DNA which is different in every person
