Hence they are also called Polytene chromosomes many threaded. This is stabilized by the peptide bond. The class was divided into two groups; groups 1 and 2 merged, groups 3 and 4 did the same.
The dark bands are darkly stained and the inter bands are lightly stained with nuclear stains. The supernatant was Ex3 chem160lab and placed in a beaker. The quaternary structure of a protein determines how the different subunits of the protein fit into an organized whole.
Chironomuslarva, Drosophila melanogaster. Ophardt, C.
Corrections are due a week after the assignment was returned, with corrections no longer accepted after an answer key has been released. We then find the minimal k such that the total size of the first k objects according to this order exceeds B.
The larger size of the chromosomes is due to the presence of many longitudinal strands called chromonemata.
Be certain to include units with all numbers and measurements. This is stabilized by hydrophobic interactions, disulfide bridges, hydrogen bonding, ionic or electrostatic interactions and metal ion coordination Campbell, Test tube 1 which contains 0.
There should only be one data section, etc… Write all information into your notebooks directly using permanent ink, making sure that a duplicate copy is made.
In Drosophila melanogaster, for example, the chromosomes of the larval salivary glands undergo many rounds of endoreplication, to produce large amounts of glue before pupation. Please be sure to keep the following items in mind as you complete your notebooks. Affix all graphs and loose pages that are generated in the laboratory or by using spreadsheets directly into the results section.
Proteins are by far the most important of all biological compounds. Attendance: Attendance is required in order to perform experiments and complete lab reports. The centromere of all these chromosomes fuse to form the chromocentre. Band Pattern The Polytene chromosome contains two types of transverse bands, namely dark bands and inter bands.

We assume without loss of generality, that for every object i we have si B (or else we can remove the object from the set of objects). I. Learning Outcomes.
