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?

Below is an mRNA sequence. When it is read, what is the sequence of amino acids that would be found in the protein? Remember to follow the rules for how mRNA is read. 5′ C C G A U G G G C C U C U A U U A A A C C 3′

Which of the following is a similarity between mitosis and meiosis?

What is true of linked genes?

In your body, different cells have different structures and functions. What is the primary reason cells within your body have different structures and functions?

Above are four diagrams illustrating cells during division. In all cases, the parent cell was a diploid cell with two pairs of chromosomes. Cell A is in [a] of [b]. Cell B is in [c] of [d]. Cell C is in [e] of [f]. Cell D is in [g] of [h].

A large group of plants are growing in neutral (pH 7) soil, and produce pink flowers every year when they bloom. Acid rain decreases the pH of the soil to 5.5, making it acidic. Once the soil becomes acidic, the same plants produce blue flowers when they bloom. What is the most likely reason for this?

Choose the recursive formula for the Fibonacci series, (where n>=1).
