- the expression of a gene can affect cell function in more than one way.
- a gene may be expressed in different cell types in a multicellular organism.
- a gene may be expressed at different stages of development.

- Which of the following mutations will result in cancer? a. homozygous recessive mutation in a tumor-suppressor gene coding for a nonfunctional protein b. dominant mutation in a tumor-suppressor gene in which the normal protein product is overexpressed c. homozygous recessive mutation in which there is a deletion in the coding region of a proto-oncogene, leaving it nonfunctional d. dominant mutation in a proto-oncogene in which the normal protein product is overexpressedarrow_forwardWhat piece of a transcript is utilized to localize the mRNA and why is this critical to development? a. 3'UTR; protein gradients have a large influence on gene expression of cells b. 5'UTR; protein gradients have a large influence on gene expression in cells c. the promoter; it has a large influence on protein production within a cell d.

- How may genes play a role in the susceptibility of inheriting cancers? The reproductive system discusses reproductive disorders like breast and prostate cancer. So, if an individual has a mutated gene such as the BRCA gene do you think the environment could play a role in gene expression?arrow_forwardFragile 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? A - The male offspring would exhibit Fragile X syndrome because Fragile X is an X-linked recessive trait. B - The female offspring would exhibit Fragile X syndrome because Fragile…arrow_forwardFragile X syndrome, caused by a change in the FMR1 gene, is the most common form of intellectual disability.
