How would a human cell normally change its expression of the gene for tyrosine aminotransferase? adipose cells will turn on this gene in the presence of glucocorticoids liver cells will turn on this gene in the presence of glucocorticoids liver cells will turn on this gene in the absence of glucocorticoids liver cells will turn off this gene in the presence of glucocorticoids adipose cells will turn off this gene in the absence of glucocorticoids
Gene Interactions
When the expression of a single trait is influenced by two or more different non-allelic genes, it is termed as genetic interaction. According to Mendel's law of inheritance, each gene functions in its own way and does not depend on the function of another gene, i.e., a single gene controls each of seven characteristics considered, but the complex contribution of many different genes determine many traits of an organism.
Gene Expression
Gene expression is a process by which the instructions present in deoxyribonucleic acid (DNA) are converted into useful molecules such as proteins, and functional messenger ribonucleic (mRNA) molecules in the case of non-protein-coding genes.
How would a human cell normally change its expression of the gene for tyrosine aminotransferase?
- adipose cells will turn on this gene in the presence of glucocorticoids
- liver cells will turn on this gene in the presence of glucocorticoids
- liver cells will turn on this gene in the absence of glucocorticoids
- liver cells will turn off this gene in the presence of glucocorticoids
- adipose cells will turn off this gene in the absence of glucocorticoids
The function of a gene can be studied through expression in a particular cell and its interactions with other genes. The gene undergoes transcription to form mRNA that can be used to study the expression.
