Rating

The authors of the research presented in this special collection used the first description of the B73 maize genome to probe some of the most intriguing questions in genetics and plant biology. Read about maize centromeres, new insights into transposon types and distribution, the abundance of very short FLcDNAs encoding predicted peptides, and many other "genetic jewels" contained herein.

7.4 Matter Cycling & Photosynthesis - Unit Overview
Unrestricted Use
CC BY
Rating

This unit on matter cycling and photosynthesis begins with students reflecting on what they ate for breakfast. Students are prompted to consider where their food comes from and consider which breakfast items might be from plants. Then students taste a common breakfast food, maple syrup, and see that according to the label, it is 100% from a tree.

Based on the preceding unit, students argue that they know what happens to the sugar in syrup when they consume it. It is absorbed into the circulatory system and transported to cells in their body to be used for fuel. Students explore what else is in food and discover that food from plants, like bananas, peanut butter, beans, avocado, and almonds, not only have sugars but proteins and fats as well. This discovery leads them to wonder how plants are getting these food molecules and where a plant’s food comes from.

AMINO ACID FREQUENCY
Unrestricted Use
CC BY
Rating

Introduction: Genetic information contained in mRNA is in the form of codons, sequences of three nucleotides, which are translated into amino acids which then combine to form proteins. At certain sites in a protein's structure, amino acid composition is not critical. Yet certain amino acids occur at such sites up to six times more often than other amino acids. In the 1960's, molecular biologists sought to determine if amino acid composition was a reflection of the genetic code or if certain amino acids were naturally selected as optimal.

Question: Are frequencies of particular amino acids simply a consequence of random permutations of the genetic code or instead a product of natural selection?

ANTIBODY BINDING
Unrestricted Use
CC BY
Rating

Introduction: Antibodies are proteins that react with foreign invaders during a humoral immune response. Antigens, small substituents of foreign invaders, elicit an immune response when they bind to the antibody. Variable regions of amino acid chains comprising the antibody create binding sites. A particular antibody has specificity to bind to one or more particular antigens.

Questions: How is antigen binding to an antibody related to antigen concentration? How can we determine binding properties of antibodies?
