Almost all the cells in an organism are genetically identical, but different types of cells look different which results from differential gene expression. Genes are expressed by turning on and turning off its expression as a result of interaction with regulatory proteins.

Expert Solution & Answer

Answer to Problem 1MCQ

Correct answer:

A pancreas cell has a different function and structure from a brain cell, but the cells have identical DNA. Therefore, option d is correct.

Explanation of Solution

Reason for the correct statement:

Differential gene expression is responsible for the specialization of different cells with the same genome to perform different functions within an organism. Hence, all the cells in a body contain similar DNA.

Hence, option d is correct.

Reasons for incorrect statements:

Option (a) is given as “because the cells contain different genes”.

The entire cells in a body contain similar genetic content. Hence, it is a wrong answer.

Option (b) is given as “because the cells contain different chromosomes”.

The entire cells in a body contain similar chromosomes. Hence, it is a wrong answer.

Option (c) is given as “because the cells have different replication proteins”.

All the eukaryotic cells contain same replication protein. Hence, it is a wrong answer.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

The entire cells in a body contain similar DNA. Differentiation is the process by which cells become different in structure and function.

After you feel comfortable with your counting method and identifying cells in the various stages of mitosis, use the four images below of whitefish blastula to count the cells in each stage until you reach 100 total cells, recording your data below in Data Table 1. (You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.) Data Table 1Stage Totals PercentInterphase Mitosis: Prophase Metaphase Anaphase Telophase Cytokinesis Totals 100 100% To find the length of time whitefish blastula cells spend in each stage, multiply the percent (recorded as a decimal, in other words take the percent number and divide by 100) by 24 hours.
