MCAT Biological and Biochemical Foundations of Living Systems Flashcards: 2c Cell Differentiation Development

Study 2c Cell Differentiation Development in MCAT Biological and Biochemical Foundations of Living Systems with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

Identify the mechanism: a microRNA binds an mRNA and reduces its protein output.

ANSWER

Post-transcriptional gene silencing via mRNA degradation or translation inhibition. MicroRNAs pair with target mRNAs to recruit RISC, leading to cleavage or translational repression for fine-tuned gene regulation.

Practice questions

1 of 50Practice questions for this set

Researchers observe that two daughter cells produced by an asymmetric division show different levels of a fate determinant protein (Det-1). The daughter with higher Det-1 later expresses a lineage marker; the daughter with lower Det-1 does not. Blocking polarized localization of Det-1 before division makes both daughters similar and reduces marker expression overall. Cellular principle assessed: asymmetric segregation of cell fate determinants. Which mechanism best explains the development of different cell types?
