BIOLOGY 1610 FINAL EXAM REVIEW -SOLVED
The amount of energy required to raise the temperature of 1 gram of a substance
(which might not be water) by one degree Celsius. - ANSWER-Specific Heat
Which of the following may be an example of X-linked inheritance in human males?
a. selective advantage of HbA Hb S heterozygotes
b. the higher incidence of hemophilia in males than females
c. trisomy 21
d. codominance of Ia and Ib alleles in heterozygotes
e. the presence of Barr bodies - ANSWER-a. selective advantage of HbA Hb S
heterozygotes
The distance between linked genes.
(This is not an absolute, standardized unit of measurement, but is relative and
represents a 1% chance of recombination.) - ANSWER-Map Unit
Fragments of DNA from two different species, such as bacterium and mammal,
spliced together in a laboratory to create one single molecule. - ANSWER-
Recombination DNA
Where does transcription occur in eukaryotes? - ANSWER-Nucleus
Where does translation always begin? - ANSWER-Cytosol
The assembly of a protein on the ribosomes, using mRNA to specify the order of
amino acids. - ANSWER-Translation
Coupled transcription and translation occur in? - ANSWER-Prokaryotic Cells
The lagging strand is synthesized as a series of smaller DNA pieces called? -
ANSWER-Okazaki Fragments
These are edited off the primary transcript in eukaryotes. - ANSWER-Introns
This micro evolutionary mechanism is usually associated with small population size.
- ANSWER-Genetic Drift
Assuming complete dominance, how could you determine the unknown genotype of
a dominant phenotype individual? - ANSWER-Testcross
When looking at Morgan's crosses, which term did we use to indicate the most
common phenotype found in nature for any given character? - ANSWER-Wild Type
What are Francis Cricks THREE contributions to biology and genetics. - ANSWER-1.
Double Helix Model
, 2. Wobble
3. The Central Dogma of Biology
The structure of DNA, in which two complementary polynucleotide strands coil
around a common helix axis. - ANSWER-The Double Helix Model
In genetics, the phenotype or genotype that is characteristic of the majority of
individuals of a species in a natural environment. - ANSWER-Wild Type
The realized expression of the genotype; the physical appearance of functional
expression of a trait. - ANSWER-Phenotype
The genetic constitution underlying a single trait or set of traits. - ANSWER-
Genotype
A junction between adjacent animal cells that allows the passage of materials
between the cells. - ANSWER-Gap Junction
The vehicle by which hereditary information is physically transmitted from one
generation to the next. - ANSWER-Chromosome
One pair of chromosomes of the same kind located in a diploid cell. - ANSWER-
Homologue
When there is only one set of chromosomes present (n) - ANSWER-Haploid
When there are two sets of chromosomes present (2n) - ANSWER-Diploid
A haploid reproductive cell - ANSWER-Gamete
The diploid (2n) cell resulting from the fusion of male and female gametes. -
ANSWER-Zygote
This type of molecule transfers amino acids from the cytoplasm to the site of
translation. - ANSWER-tRNA (transfer RNA)
Briefly, what is the population that is IN the Hardy Weinberg equilibrium doing or
not doing?
a. it is gradually evolving
b. its members are not randomly mating
c. it is experiencing a bottleneck
d. it is not evolving at this time
e. it is rapidly evolving - ANSWER-d. it is not evolving at this time.
During the translations initiation, what binds to the mRNA start codon? - ANSWER-
initiation RNA
What model is the accepted model for DNA replication? - ANSWER-semi
