BIO 112 EXAM 2 (CHAPTERS 6-10)
QUESTIONS AND ANSWERS
Diploid - Correct Answers -containing two complete sets of chromosomes, one from
each parent.
Haploid - Correct Answers -An organism or cell having only one complete set of
chromosomes.
Crossing Over - Correct Answers -the exchange of genes between homologous
chromosomes, resulting in a mixture of parental characteristics in offspring.
Independent Assortment - Correct Answers -One of Mendel's principles that states that
genes for different traits can segregate independently during the formation of gametes
Genome - Correct Answers -All the genetic information in an organism; all of an
organism's chromosomes.
Enzymes - Correct Answers -Catalysts for chemical reactions in living things. Proteins
that speed up chemical reactions.
Zygote - Correct Answers -a diploid cell resulting from the fusion of two haploid
gametes; a fertilized ovum or egg.
Chromosome - Correct Answers -a threadlike structure of nucleic acids and protein
found in the nucleus of most living cells, carrying genetic information in the form of
genes.
Autosome - Correct Answers -Any chromosome that is not a sex chromosome. 22 pairs
of autosomes with one X and either another X or a Y.
Endergonic - Correct Answers -A chemical reaction that requires the input of energy in
order to proceed.
Exergonic - Correct Answers -Chemical reactions that release energy
Coupled Reactions - Correct Answers -pairs of chemical reactions in which some of the
energy released from the breakdown of one compound is used to create a bond in the
formation of another compound
