Summary Introduction

To review:

Whether one should get tested for BRCA1 and BRCA2 as a blood test is available easily.

Introduction:

Breast cancer refers to the disease of cancer, which primarily affects the breasts of the individual, mostly females. This cancer can be genetic and BRCA genes are breast cancer genes. They are called so because mutations in these genes can cause breast cancers in both females and males. They can be passed down to the child from either parent.

Expert Solution & Answer

Explanation of Solution

There are genetic tests available to find out if the BRCA gene in an individual is mutated or not, but genetic testing is recommended to those people with high risks of developing breast cancer. For example, if a person has a family history of breast cancer, ovarian cancer or a family member with a mutated BRCA gene.

Due to the cost and time consumption, this test is not recommended to every individual who is experiencing breast cancer. This test is not recommended otherwise because there are only slight chances that a family member is a carrier of this gene mutation. Moreover, emotionally such tests impact severely and may hamper the psychosocial life of the individual and their family members.

Conclusion

Thus, it can be concluded that genetic tests are expensive and impact the person emotionally. They are only recommended to people who have a family history of breast cancer.

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. (Example: If percent is 20%, then Time in Hours = .2 * 24 = 4.8) Record your data in Data…
