Which of the following molecules are involved in pattern formation during development? A) transcription factors B) cAMP C) cytoplasmic determinants D) miRNAs

A.) transcription factors

Explanation:

Transcription factors are often very important in initiating patterns of gene expression that result in major developmental changes.

Option C, cytoplasmic determinants

Explanation:

Cytoplasmic determinants are the protein molecules and mRNA which guide the early stage development. This information is stored in the nucleus and cytoplasm of the cell. Pattern is controlled by the position of cell in an embryo. The regulatory molecules with in the cells are responsible for encoding genes for positional information. Genes such as hox genes determines the shape of the body along the body axis

Hence, option C is correct
