Question
1 ) Mitochondria are unusual organelles in that they contain their own genomes. The human mitochondrial genome is a
Select one:
single-stranded circular DNA molecule.
double-stranded circular RNA molecule.
single-stranded linear RNA molecule.
single-stranded linear DNA molecule
double-stranded circular DNA molecule.
2) Around 35,000 years ago the Neanderthals that had settled throughout Europe were restricted to living in a corner of Europe and became
Select one:
fully incorporated into the modern European group.
extinct.
more technically advanced than Homo sapiens.
more socially and culturally advanced than Homo sapiens.
the dominant population throughout Europe.
3) DNA chip technology can be used to compare the genomes of different individuals. The green and red spots on the DNA chip are illuminated with a laser to detect a DNA sequence that base pairs with a specific gene probe on the chip. Differing intensities of the green and red spots on the chip can indicate that
Select one or more:
some genes have been deleted or removed from the genome represented in one or both of the samples.
one or both of the DNA samples contain(s) different gene sequences than the control DNA sample library on the chip.
the karyotypes of the two individuals sampled will also differ.
these genomes come from identical twins.
there are gene copy number differences between the different genomes.
4) Mitochondria are maternally inherited, which means that an individual's mitochondrial genes are inherited from
Select one:
both the individual's mother and father.
the individual's mother's grandfather.
an X chromosome.
the egg cell that was fertilized to become the individual's zygote.
the individual's father.
5) Suppose you are designing a DNA fingerprint analysis. You want to improve the reliability of the fingerprint to tell the difference between the original sources of DNA samples. The best way to do this is to increase the number of DNA probes used in the fingerprint analysis.
Select one:
True
False
Explanation / Answer
1. Option e - It is a double standard circular DNA molecule.
2. They had fully incorporated into European groups. Due to effect of bottleneck ness and random matting
3. There are gene copy number difference between the different genomes.
4. The egg cell that was fertilized to form zygote - Because father does not contribute to nutrition they contribute only the nuclear DNA via sperm
5. True - The increased number of DNA probes will give more clearance and accurate results.
