The gene atg-12 codes for a protein associated with abnormal rates of cell destruction and recycling of cell contents. Scientists studying bacterial plasmids devised an experiment using recombinant DNA techniques to remove a section of DNA (gene atg-12) of a bacterial plasmid (POKE103) and create a new plasmid (POKE104) that did not contain the gene atg-12. The new plasmid was then incorporated within the DNA of the fungus Neurospora crassa in cellular studies. Which statement explains the expected heredity of fungi that incorporate POKE104? Fungi that incorporate POKE104 will produce the protein from gene atg-12 and have increased rates of malignant tumors. Fungi that incorporate pOKE104 will not produce the protein from gene atg-12 but will have a normal appearance. The prokaryotic DNA will remain separate within the fungal cells, produce the protein from gene atg-12, and have increased rates of malignant tumors. The prokaryotic DNA will remain separate within the fungal cells and not produce the protein from gene atg-12, but will have a normal appearance.

Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
Question
Transcribed Image Text:The gene atg-12 codes for a protein associated with abnormal rates of cell destruction and
recycling of cell contents. Scientists studying bacterial plasmids devised an experiment
using recombinant DNA techniques to remove a section of DNA (gene atg-12) of a
bacterial plasmid (POKE103) and create a new plasmid (POKE104) that did not contain
the gene atg-12. The new plasmid was then incorporated within the DNA of the fungus
Neurospora crassa in cellular studies.
Which statement explains the expected heredity of fungi that incorporate POKE104?
Fungi that incorporate pOKE104 will produce the protein from gene atg-12 and have
increased rates of malignant tumors.
Fungi that incorporate pOKE104 will not produce the protein from gene atg-12 but will have
a normal appearance.
The prokaryotic DNA will remain separate within the fungal cells, produce the protein from
gene atg-12, and have increased rates of malignant tumors.
The prokaryotic DNA will remain separate within the fungal cells and not produce the
protein from gene atg-12, but will have a normal appearance.
Transcribed Image Text:Fragile X syndrome, caused by a change in the FMR1 gene, is the most common form of
intellectual disability. In patients with this syndrome, a small part of the gene is repeated
several times in one area of the chromosome. This defect in the gene makes the body
unable to produce adequate amounts of a protein needed for normal brain functioning. In
males, this syndrome causes a moderate intellectual disability, and in females, a mild
intellectual disability.
A family that exhibits Fragile X syndrome is shown in the pedigree. In the pedigree, squares
represent males and circles represent females. Shaded symbols represent a person with
the disorder.

Which of the following correctly predicts the outcome if offspring 11 mated with a
homozygous normal female, based on the inheritance pattern shown in the pedigree?
The male offspring would exhibit Fragile X syndrome because Fragile X is an X-linked
recessive trait.
The female offspring would exhibit Fragile X syndrome because Fragile X is a recessive
autosomal trait.
None of their offspring would exhibit Fragile X syndrome because Fragile X is an X-linked
dominant trait.
Both the male and female offspring exhibit Fragile X syndrome because Fragile X is a
dominant autosomal trait.
