Understand the concept of sister chromatids: Sister chromatids are identical copies of a single chromosome that are connected by a centromere. They are formed during DNA replication in the S phase of the cell cycle.
Identify the chromosomes in the image: Look for structures that appear as X-shaped figures, which represent duplicated chromosomes consisting of two sister chromatids.
Count the number of X-shaped figures: Each X-shaped figure represents one pair of sister chromatids. Therefore, count each X-shaped figure to determine the total number of sister chromatids.
Multiply the number of X-shaped figures by two: Since each X-shaped figure consists of two sister chromatids, multiply the number of X-shaped figures by two to find the total number of sister chromatids.
Verify your count: Double-check your count to ensure accuracy, considering that each chromosome should have two sister chromatids.
