Recent research has highlighted the role of viral relics in the human genome in early embryonic development. Explain the function of MLT2A1 in embryonic gene activation and discuss its potential significance in assisted reproductive technologies.
Tips for your answer
- Begin with the biological context: Briefly explain embryonic gene activation (zygote genome activation) and why it is essential for early human development. This sets conceptual clarity from the first paragraph.
- Explain the mechanism concisely: Clearly state how MLT2A1, a viral relic, forms hybrid RNA molecules that help locate target genes and recruit activating proteins. Avoid excessive technical jargon; focus on the cause–effect link.
- Link to application and relevance: Conclude by connecting the discovery to assisted reproductive technologies, especially embryo viability assessment in IVF, to show applied understanding—key for higher marks.
