The expression of a gene may depend on _______.
- a. the type of organism
- b. environmental conditions
- c. the type of cell
- d. all of the above

Concept introduction: Genes are the fundamental units of heredity, which are composed of DNA. Each gene specifies a particular protein. For this, the genes will be converted into a useful product through the process of gene expression. Gene expression involves the conversion of DNA into RNA through the process of transcription. Then, this RNA will be converted into proteins through the process of translation.
Answer to Problem 1SQ
Correct answer: The expression of a gene may depend on the type of organism, environmental conditions and the type of cell.
Therefore, option d. is correct.
Explanation of Solution
Reason for the correct statement:
The gene expression depends upon many factors including the type of organism, environmental conditions and the cell type.
Based upon the type of organism (simple and complex) the gene expressions vary.
Every cell has its own environmental conditions which contain the proteins. Depending upon the location of each of these proteins, the gene expressions may vary.
There are many types of cells that perform different specialized functions. Each cell will adjust to the metabolism by adjusting the gene expression. Also, the multicellular organisms will modify their body structure and function by regulating the gene expression.
Hence, option d. is correct.
Reasons for the incorrect statements:
Option a. is given as, “the type of organism”.
The organisms can be simple or complex depending upon their physiology and anatomical organization. Based upon the type of organism, the gene expressions vary. The given option is correct but the gene expression also depends upon the environmental conditions and the type of cell.
Hence, option a. is incorrect.
Option b. is given as, “environmental conditions”.
Every cell has its own environmental conditions (extracellular and intracellular conditions) which contain the proteins. Depending upon the location of each of these proteins, the gene expressions may vary. The given option is correct but the gene expression also depends upon the type of organism and the type of cell.
Hence, option b is incorrect.
Option c. is given as, “the type of cell”.
There are many types of cells that perform different specialized functions. Each cell will adjust to the metabolism by adjusting the gene expression. The given option is correct but the gene expression also depends upon the environmental conditions and the type of organism.
Hence, option c. is incorrect.
Hence, options a., b., and c. are incorrect.

What would be the protein needs of a man named Josh who exercises moderately and is the same age and size as Wayne? Josh is 5 ft, 8 in tall and weighs 183 lb. Round the number of grams to the nearest whole number. During calculations, use numbers rounded to the first decimal place.
