Introduction:

DNA is considered as a blueprint of a cell, as it plays an important role in long-term information storage. DNA is the genetic material of all living organisms and viruses except RNA viruses. Proteins are polymers of amino acids that play structural, functional and regulatory roles in cells.

Expert Solution & Answer

Explanation of Solution

DNA: DNA is present in all living organisms and in some viruses. DNA is made up of the ribose sugar, a nitrogenous base, and a phosphate group. DNA plays an important role in a cell as it contains all the information required by a cell for its development and function. It acts as a genetic material and helps in the transfer of hereditary information.

Protein: Proteins are complex biomolecules, made up of long chains of amino acids. Proteins play many important roles in a cell. Proteins are needed for structure (keratin), function (hemoglobin), and regulation (enzymes).

Conclusion

DNA and protein playing important roles in a cell are considered as molecules of life. The proteins help in the maintenance of a normal structure and function in the body.

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…

Question #5: Assume that two genes are identified that confer gametophytic facultative apomixis in soybean. The genes show independent assortment. Recessive alleles at both loci are required for the facultative apomixis. Facultative apomixis is triggered when the temperature at pollination is above 20 degrees C. At temperatures below 20 degrees C, all reproduction is sexual, independent of genotype. A facultative apomict male, capable of producing viable pollen, was crossed with a sexually reproducing female. Assuming the parents are completely inbred, what are the predicted phenotypic ratios (apomict: non-apomict) for the F1, F2, and DH (F1-derived) generations at each of the following temperatures*: a) 15°C? b) 25°C? *for full credit, show crosses and genotypes where appropriate. Remember to position the female first (left side) in the cross. Type your answer here:
