Additional Problems
Transposons are made of:a. segments of RNAb. segments of DNAc. protein
A transposon can do all of the following except:a. move from a plasmid into the recipient cell genomeb. move from one site on the host genome to another site on the host genomec. move from a host genome to a plasmidd. make a copy of itself, leaving the copy in the original position as it movese. lyse the host chromosome to which it is transferred
Transposons are...a. segments of messenger RNAb. plasmidsc. segments of transfer RNAd. segments of DNA
A scientist study the role of PITX1 in the development of hard tissues in the Antler Eel finds that PITX1 is expressed in the spines of the fins and that an almost identical gene is expressed in the antlers. This second gene probably arose due toa. a change in a regulatory gene  b. a change in a coding gene  c. gene duplicationd. changes in histone acetylation  e.  changes in bicoid
A transposon can only enter a bacterial cell by a bacteriophage.a. Trueb. False
A transposon can move from the host DNA to a plasmid.a. Trueb. False
Which of the following individuals is most likely to be a chimera? a. A man who has no siblings b. A person created through in vitro fertilizationc. A person with an identical twin d. A woman who has had children
A genetic change that caused a certain Hox gene to be expressed along the tip of a vertebrate limb bud instead of farther back helped make possible the evolution of the tetrapod limb. This type of change is illustrative of:a. the influence of environment on development.b. heterochrony.c. a change in a developmental gene or its regulation that altered the spatial organization of body parts.d. gene duplication.
The full set of genes of an individual is called _____.a. a genomeb. a vectorc. a plasmidd. recombinant DNA
It is estimated that there are _____ human genes.a. 100b. 250c. 500d. 1000+
Transposable elements: a. Are segments of RNA found in chromosomesb. Are another name for translocationsc. Are DNA sequences that can "jump" within the genomed. Result from damage to the chromosomes by things like radiatione. Are formed during transcription
What is the role of gene duplication in the process of evolution?A. Gene duplication has been essential to the destruction of new genes.B. Gene duplication has been essential to the origin of new genes.C. Gene duplication is the only source of gene mutation.D. Gene duplication prevents gene mutation.
