Are genes composed of hormones?
No, genes are not composed of hormones. Genes are segments of DNA that contain the instructions for producing proteins, while hormones are chemical messengers produced by various glands in the body that regulate different physiological processes. While genes can influence the production and regulation of certain hormones, they are not composed of hormones.
Which exception to Mendelism involves the expression of traits that are controlled by multiple genes?
The exception to Mendelism that involves the expression of traits controlled by multiple genes is called polygenic inheritance. In this type of inheritance, multiple genes contribute to the observable trait, and the trait often shows a continuous variation instead of distinct categories. Examples of polygenic traits include height, skin color, and intelligence.
What are chemical factors that determines traits?
Chemical factors that determine traits include DNA, which encodes genetic information that determines an organism's characteristics, as well as hormones and other signaling molecules that regulate gene expression and cell function. Environmental factors can also influence trait expression by affecting how genes are activated or suppressed.
What cellular process leads to the production milk-specific mRNA molecules?
The process of lactation in mammary epithelial cells involves the upregulation of specific genes, including those responsible for producing milk-specific mRNA molecules. This process is controlled by hormones such as prolactin and glucocorticoids, which stimulate the expression of genes involved in milk production. The milk-specific mRNA molecules are then translated into proteins needed for milk synthesis.
Eukaryotic are controlled by what group of proteins?
Eukaryotic cells are controlled by a group of proteins called transcription factors. These proteins regulate the transcription of genes by binding to specific DNA sequences and influencing the expression of those genes. They play a crucial role in gene regulation and cell function in eukaryotic organisms.
What are sexlinked genes?
Genes that are location on the sex chromosomes.
What can sometimes influence expression of genes?
Several factors determine the final outcome of gene expression. They include the cell's environment, the presence of other cells, and the timing of gene expression. hope this helped! -Steph
What three ways are human traits controlled?
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.

Are all characteristics controlled by only 1 gene?
No, characteristics can be controlled by multiple genes interacting with each other. This is known as polygenic inheritance. Additionally, environmental factors can also influence the expression of these genes, further complicating the determination of specific genetic control.
What does the operon model attempt explain?
The operon model attempts to explain how genes are regulated in prokaryotic cells. It describes how genes are grouped together into operons, which are clusters of genes that are transcribed together as a single mRNA molecule. The model also explains how the expression of these operons is controlled by regulatory elements such as promoters, repressors, and activators.
The trait of an organism is controlled by what?
The trait of an organism is controlled by its genes, which are segments of DNA that provide instructions for building and maintaining the organism. Genes influence various traits such as physical appearance, behavior, and susceptibility to diseases. Environmental factors can also play a role in the expression of traits.
What are chemical factors that determines traits?
Chemical factors that determine traits include DNA, which encodes genetic information that determines an organism's characteristics, as well as hormones and other signaling molecules that regulate gene expression and cell function. Environmental factors can also influence trait expression by affecting how genes are activated or suppressed.
What are the traits of an organisms are controlled?
Traits are controlled by the genes of the parents.
