Question
An occurrence when a section of a chromosome relocates itself to a non-homologous chromosome is called a/an:
Inversion mutation
Translocation mutation
Transformation mutation
Duplication mutation
a group formed to evaluate moral and ethical concerns arising from the Human Genome Project is:
ELSI
NIES
MORA
SILES
Patterns made by restriction fragments in an agarose gel creates a/an:
Southern Blot
Northern Blot
VNTR
DNA fingerprint
Mutations and polymorphisms both involve changes in DNA, but polymorphisms are more common because:
mutations are always lethal.
more people have them.
mutations refer to a real situation, whereas polymorphisms are more hypothetical and used by biologists to explain genetic changes in an entire population.
they affect phenotype less severely and allow individuals to reproduce and transmit them to future generations.
The promoter of a gene is the part of a gene that marks the:
start point of translation
start point of a gene
end point of transcription
end point of translation
Histone proteins:
control gene expression through chemical interactions that expose parts of the DNA to translation factors.
bind to tRNAs to prevent translation
control gene expression through chemical interactions that expose parts of the DNA to transcription factors.
bind to mRNAs to prevent translation
A retrovirus produces an enzyme called reverse transcriptase, which copies the RNA genome into the DNA of the host. This process is the opposite of the central dogma of DNA because:
a retrovirus mutates too much to follow the central dogma of DNA.
a retrovirus lacks RNA.
the central dogma states that DNA is copied into RNA.
a retrovirus cannot exist in human cells
Which of the following is most correct regarding genes, DNA, and protein?
A gene is a section of a chromosomal DNA composed of many amino acids.
DNA is composed of many genes, which are formed from amino acid sequences
DNA is composed of many amino acids, which encode the protein and genotype
A gene is a section of DNA whose sequence encodes a particular protein, which is composed of amino acids.
If the sequence of one strand of a DNA molecule is 5' ATGGCAT 3', the sequence of the complementary strand would be:
5' ATGGCAT 3'
3' ATGGCAT 5'
5' TACCGTA 3'
3' TACCGTA 5'
Interphase consists of:
mitosis and cytokinesis
S, G2, and prophase
G1, S, G2
prophase, metaphase, anaphase, and telophase
The DNA of dizygotic twins is:
identical in the number and distribution of alleles, but not necessarily identical in gene sequence
different in the number and distribution of alleles, but identical in gene sequence
identical in the number and distribution of alleles, and identical in gene sequence
as alike as the DNA of any two full-siblings
X inactivation is controlled by:
the XIST gene
the SRY gene
the XTASY gene
the INACT gene
In genomic imprinting, the expression of a genetic disorder depends on:
the age of the mother when she became pregnant
whether the trait is X-linked or autosomal
the number of autosomal genes transmitted
which parent transmits the disease-causing allele
Greg experiences severe withdrawal symptoms when he stops taking hydrocodone which is a drug he originally took to alleviate his leg pain, but hasn't been able to quit. Greg is exhibiting:
tolerance
paranoia
ideation
dependence
SSRIs treat depression by:
inhibiting the production of serotonin
preventing postsynaptic neurons from releasing serotonin from the synapse
preventing pre-synaptic neurons from taking up serotonin from the synapse
releasing endorphins in the plasma membranes of the postsynaptic neurons
Explanation / Answer
An occurrence when a section of a chromosome relocates itself to a non-homologous chromosome is called a/an:
The answer is Translocation mutation
If only one chromosome have this out of two, that organism is called as translocation heterzygote and if both are involved in that translocation that is reffered as translocation homozygote.
If that section of choromosome relocates to a homologues it will an duplication mutation.
a group formed to evaluate moral and ethical concerns arising from the Human Genome Project is:
The answer is ELSI.
ELSI stands for Ethical, Legal, and Social Implications. This ELSI is an integral part of the Human Genome Project which is launched in 1990.
Patterns made by restriction fragments in an agarose gel creates a/an:
The answer is DNA fingerprint.
