In a laboratory experiment, scientists investigate the regulation of gene expression through transcription. They observe that a specific transcription factor binds to enhancer regions upstream of a gene, leading to increased transcription activity. What role does this transcription factor play in the regulation of gene expression?

If a heterozygous plant (Rr) is crossed with another heterozygous plant (Rr), what is the expected phenotypic ratio of the F2 offspring according to Mendel’s laws?

In a genetics research project, scientists isolate a DNA sample from a newly discovered species of plant. After analysis, they determine that the DNA sample contains 30% adenine. What percentage of the nucleotide base would be guanine (G) in this DNA sample?

A father with normal vision (not colorblind) and a carrier mother have children. What is the expected probability that a son will be colorblind?

A geneticist is studying a gene associated with a rare genetic disorder. They sequence the gene and identify several segments: one segment contains the coding sequence for the protein, while another segment does not code for protein but is transcribed into mRNA. Identify the the 1st and 2nd segment in the question stem.

Which stage of cellular respiration generates the majority of ATP molecules through oxidative phosphorylation?

Which stage of cellular respiration takes place in the cytoplasm of the cell?

Which step of the scientific method involves making predictions based on the hypothesis and designing experiments to test them?

Which organelle in eukaryotic cells is responsible for the synthesis of proteins?

If a pea plant with yellow seeds (YY) is crossed with a pea plant with green seeds (yy), what will be the genotype of the F1 generation?
