1 Genetics DNA Technology Evolution Potpourri DNA & PS

2 Having two different alleles for a trait EX Tt is called this

3 HETEROZYGOUS

4 Traits that have a bell curve of phenotypes (not just two or three) EX/ skin color, IQ, birth weight

5 POLYGENIC

6 How many chromosomes does a normal human have?

7 46

8 Where would you expect genes that assort independently to be found?

9 ON DIFFERENT CHROMOSOMES

10 If an organisms haploid number is 20, what is it’s diploid number?

11 40

12 What enzyme is used to add new DNA nucleotides to the new strands of DNA during DNA replication?

13 DNA POLYMERASE

14 Which kind of RNA brings the copy of the gene from the nucleus to the ribosomes for protein synthesis?

15 mRNA

16 Information in the cell goes from DNA  RNA  to what?

17 PROTEIN

18 If a DNA sample contains 13% Adenine, how much Guanine would it contain?

19 37%

20 This is where transcription takes place

21 NUCLEUS

22 In this process, external DNA is incorporated into a cell.

23 TRANSFORMATION

24 This process uses chopped up DNA in a gel to determine paternity or solve a crime

25 DNA FINGERPRINTING

26 DNA created by combining DNA from more than one source

27 RECOMBINANT DNA

28 These “molecular scissors” are used to cut up DNA into smaller pieces

29 RESTRICTION ENZYMES

30 Changing the sequence of DNA of an organism

31 GENETIC ENGINEERING

32 All of the genes in a population of organisms

33 GENE POOL

34 Body parts that once were useful but no longer are (EX/remnants of 3 rd eyelid & appendix in humans)

35 VESTIGIAL STRUCTURES

36 Genetic drift tends to occur more frequently if a population is this

37 SMALL

38 Natural selection acts upon these

39 PHENOTYPES PRESENT IN A POPULATION

40 When two species adapt and evolve in response to one another (EX/Bees and flowering plants)

41 COEVOLUTION

42 The two-word naming system developed by Linnaeus

43 BINOMIAL NOMENCLATURE

44 Using binomial nomenclature, which word gets capitalized?

45 GENUS ex/ Felis domesticus (Genus) (species)

46 Selection that favors the average phenotype (pressure against two extremes)

47 STABILIZING

48 Failure of chromosomes to separate during meiosis

49 NONDISJUNCTION

50 Genes contain the instructions for building these:

51 PROTEINS
