Concept explainers
To estimate: The percentage of the testcross progeny a/a · b/b if the two genes are unlinked.
Introduction: The unlinked genes or genes that occur on separate chromosomes assort independently during gamete formation.
To estimate: The percentage of the testcross progeny a/a · b/b if the two genes are completely linked.
Introduction: The genes that are found on the same chromosome forms a linkage and are inherited together. This means that they are assorted in a non-independent way.
To estimate: The percentage of the testcross progeny a/a · b/b if the two genes are 10 m.u. apart.
Introduction: The map unit or the physical distance between the two genes is used to determine the percentage of recombinants that are formed after the cross. As for map unit = % recombination.
To estimate: The percentage of the testcross progeny a/a · b/b if the two genes are 24 m.u. apart.
Introduction: The map units indicate the distance between two gene loci and the recombination frequencies of the progenies.

Transcription and Translation Practice: (Video 10-1 and 10-2) A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense DNA strand and label the 5' and 3' ends. B. Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forwardWhat is the structure and function of Eukaryotic cells, including their organelles?

Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas.
