What are three environmental factors that can alter gene expression?
Environmental factors such as food, drugs, or exposure to toxins can cause epigenetic changes by altering the way molecules bind to DNA or changing the structure of proteins that DNA wraps around.
What are some environmental factors that can influence gene expression quizlet?
What are some environmental factors that can influence gene expression? Temperature, nutrition, light, chemicals, infectious agents, age, and gender/sex.
What are 3 environmental factors that can affect traits?
Food, temperature, sunlight, and water are examples of environmental factors that can affect an organism’s traits. Many characteristics of plants and animals involve both inheritance and the environment.
How does temperature affect gene expression?
Generally, increasing temperature caused acceleration in development and the higher the temperature, the earlier the expression response of any specific targeted gene. In more detail, larval yolk utilization and growth rates increased, while yolk utilization efficiency decreased with increasing temperature.
What are two internal factors that affect gene expression?
Changes in gene expression can be induced by external factors like environment (diet, smoking), internal signals such as stress (hypoxia, nutrient deprivation), inflammation and tissue repair, and even genetic material such as non-coding RNAs.
Which of the following is an example of environmental impacts on the expression of traits?
Which of the following is an example of environmental impacts on the expression of traits? Animal coat color shifts in response to seasonal changes in day length and temperature.
What influences gene expression by affecting the rate of translation quizlet?
Ribosomes, aminoacyl tRNAs, initiation factors, and elongation factors are all required for the translation of mRNA molecules. The availability of these components affects the rate of translation and therefore influences gene expression.
What type of genes affect other gene expression quizlet?
In the steps, adenine is paired with thymine and guanine is paired with cytosine. Each pair of bases is held together by a hydrogen bond. A gene consists of a sequence of bases. Sequences of three bases code for an amino acid (amino acids are the building blocks of proteins) or other information.
