Since the discovery of the green fluorescent protein gene, fluorescent proteins have impacted molecular cell biology. This protocol describes how expression of distinct fluorescent proteins through genetic engineering is used for barcoding individual cells. The procedure enables tracking distinct populations in a cell mixture, which is ideal for multiplexed applications.

Optical detection of ultrasound is impractical in many imaging scenarios because it often requires stable environmental conditions. We demonstrate an optical technique for ultrasound sensing in volatile environments with miniaturization and sensitivity levels appropriate for optoacoustic imaging in restrictive scenarios, e.g. intravascular applications.

2023
Many human diseases are associated with mutations or variations in genetic sequences. Some of these genetic variants are heritable, passed down from generation to generation, while others arise sporadically during an organism’s life and cause diseases such as cancer. Researchers are trying to identify and characterize these genetic alterations in the hopes of improving diagnosis and therapeutic options for patients.In this video, we will examine the history of genetic disease research, and...

Genetic Crosses

2023
To dissect genetic processes or create organisms with novel suites of traits, scientists can perform genetic crosses, or the purposeful mating of two organisms. The recombination of parental genetic material in the offspring allows researchers to deduce the functions, interactions, and locations of genes. This video will examine how genetic crosses were influential in developing Mendel's three laws of inheritance, which form the basis of our understanding of genetics. One genetic crossing...

FAQs
Interpretation begins by relating a DNA sequence or chromosome change to biological pathways and observable clinical traits. This genotype–phenotype connection helps distinguish a molecular finding that may explain disease from information that is useful for risk assessment or management. It also provides the biological basis for more informed clinical decisions and counseling.
Different methods reveal different forms of genetic information. Sequencing examines DNA sequence, whereas karyotyping addresses chromosome-level changes; family inheritance analysis adds evidence about how a trait or disorder appears across relatives. Considering these approaches together can broaden interpretation when one type of test alone does not fully explain the clinical picture.
Responsible interpretation is essential because genetic data must be linked carefully to clinical traits and biological pathways. A result may contribute to diagnosis, risk assessment, or treatment selection only when its significance is understood in context. This caution supports appropriate counseling and reduces the chance that genetic information will be used without adequate clinical meaning.
Testing may include sequencing, karyotyping, or analysis of family inheritance patterns, depending on the genetic information being sought. The resulting findings are then connected with biological pathways and clinical traits, rather than considered in isolation. This workflow supports diagnosis, risk assessment, or management when the evidence is relevant to the clinical situation.
Applications extend across several clinical decisions. For rare disorders, testing can help investigate a suspected molecular cause; carrier and prenatal screening address inherited-risk questions; and cancer predisposition evaluation examines genetic risk relevant to cancer. Each use asks a different question, so interpretation must remain aligned with the purpose of the assessment.
When a molecular cause is identified, genetic findings can help guide selection of targeted treatments. Medical genetics also informs genetic counseling by translating results into clinically relevant risk or management discussions. This connection between molecular evidence and care supports precision medicine, while responsible use of genetic data remains necessary throughout decision-making.
