Prokaryotic and eukaryotic cells can regulate gene expression. Which of the following mechanisms is seen in eukaryotes, but NOT in prokaryotes?

In organisms that reproduce sexually, what contributes to genetic variation among offspring?

A red-flowered plant is crossed with a white-flowered one. All the offspring produce pink flowers. What can we conclude from this?

A diploid cell that goes through meiosis will always produce _____.

An individual has the genotype AaBbCcDd (the four genes are unlinked). The individual produces gametes. Which of the following gamete genotypes could only occur if there were mistakes during meiosis? Choose both correct answers.

What carries out each of the following processes?

What is true of genes?

In an insect, large wings (L) are dominant to small wings (l). Two insects are crossed. If the offspring are 104 small-winged and 302 large-winged, what are the most likely genotypes of the parents?

Earlier in the course, we looked at four groups of macromolecules: proteins, nucleic acids (ribonucleic acid and deoxyribonucleic acid), carbohydrates, and lipids (fats, phospholipids, and steroids). Transcription synthesizes [a] . Translation synthesizes [b].

The human genome project revealed that humans have approximately 20,000 protein-coding genes, but produce well over 20,000 different proteins. What best explains this?
