A molecular state machine is implemented in a cell by designing the cell to use specific homology directed repair (“HDR”) templates for repairing double strand breaks in polynucleotides based on a current “state” of the cell. The state may be established by the presence of a molecule in the cell or by the availability of specific cut sites in the polynucleotides of the cell. Different HDR templates or different nucleases may be available for performing HDR based on the state. When the state is changed, the same signal or event will result in a different HDR template being incorporated into the existing polynucleotides of the cell. Signals that are internal or external to the cell may be used to change the state of the cell. The cell may create a log of molecular events, store binary data, or perform other synthetic biology/molecular computing functions based on state.

The present invention relates to a nucleic acid molecule comprising an annexin A5 (ANXA5) gene regulation element which comprises at least one point mutation, whereby said at least one point mutation (substitution) is selected from the group consisting of (i) a point mutation G to A at a position which corresponds to nucleotide 186 of SEQ ID NO: 2; (ii) a point mutation A to C at a position which corresponds to nucleotide 203 of SEQ ID NO: 2; (iii) a point mutation T to C at a position which corresponds to nucleotide 229 of SEQ ID NO: 2; and (iv) a point mutation G to A at a position which corresponds to nucleotide 276 of SEQ ID NO: 2. Furthermore, the present invention provides for a vector comprising the nucleic acid molecule the invention and a host transformed with the vector. The invention also relates to specific uses, in particular diagnostic uses of the nucleic acid molecules described herein. Moreover, the invention relates to a method for haplotyping an ANXA5 gene regulation element in an individual comprising the steps of: (a) isolating a nucleic acid from a sample that has been removed from the individual; (b) determining the presence of the nucleotides present at positions 186, 203, 229 and 276 of the individual's copy of the ANXA5 gene regulation element, wherein the position numbers are determined by comparison to SEQ ID NO: 2; (c) assigning the individuals a particular haplotype by comparison of the nucleotides present at said positions to the nucleotides recited in the haplotypes as defined herein.

The present invention is directed generally to eukaryotic cells comprising single-celled organisms that are introduced into the eukaryotic cell through human intervention and which transfer to daughter cells of the eukaryotic cell, and methods of introducing such single-celled organisms into eukaryotic cells. The invention provides single-celled organisms that introduce a phenotype to eukaryotic cells that is maintained in daughter cells. The invention additionally provides eukaryotic cells containing magnetic bacteria. The invention further provides eukaryotic cells engineered with single-celled organisms to allow for multimodal observation of the eukaryotic cells. Each imaging method (or modality) allows the visualization of different aspects of anatomy and physiology, and combining these allows the imager to learn more about the subject being imaged.

Provided herein are genetic circuits and cell state classifiers for detecting the microRNA profile of a cell. The cell state classifiers of the present disclosure utilize phosphorylation state of a transcription factor to control classifier output. Kinases and phosphatase pairs that function in phosphorylating or dephosphorylating the transcription factor are integrated into the circuit, their expression tuned by the presence of microRNAs of interest (e.g., in a cell). The genetic circuits and cell state classifiers may be used in various applications (e.g., therapeutic or diagnostic applications).
