YÖKDİL Fen Bilimleri Advanced Exam 3

The ---- of certain genes during embryonic development is regulated by a complex interplay of transcription factors and epigenetic modifications that silence or activate specific genomic regions.

Chromosomal abnormalities, such as trisomy and monosomy, arise when errors in meiotic cell division lead to the unequal ---- of chromosomes among daughter cells.

CRISPR-Cas9 technology enables researchers to introduce precise modifications into the genome by ---- a specific DNA sequence and inducing a double-strand break at the target locus.

Polygenic traits, which are determined by the cumulative effects of multiple genes, exhibit a pattern of ---- variation that typically follows a normal distribution in a given population.

The identification of oncogenes, which are mutated forms of normal genes called proto-oncogenes, has been ---- in understanding how uncontrolled cellular proliferation leads to tumour formation.
