The following phenotypic classes reflect offspring that were generated as a result of a crossover event
- miniature wings
- garnet eyes
Explanation:
When the miniature wings and garnet eyes links up with the 8 map unit that are present between them. After that the presence of two recombinant classes must complement together and make 8% of total i.e. they contribute 4% each. together the parental classes make up to 92% by contributing 46% one.
This can be understood through a phenotypic ratio calculation, which can be expected from it.
wild type: 4% x 800 = 32
miniature wings: 46% x 800 = 368
garnet eyes: 46% x 800 = 368
miniature wings, garnet eyes: 4% x 800 = 368
Answer:
The model is in the annex
Explanation:
According to the model presented below, after the transition the RNA is in a state called pre-mRNA where we can see the presence of exons and introns. Introns are not sequences of nitrogenous bases that can participate in the production of proteins and therefore are removed from the RNA molecule through a process called splicing. Once the introns are removed, the mRNA is ready and leaves the nucleus towards the cytoplasm, by a process called exportation. Reaching the cytoplasm, the mRNA in association with the tRNA and the ribosomes will give rise to a polypeptide chain, in a process called translation, where the nitrogenous bases are transformed into amino acids.
The polypeptide chain has a linear sequence of amino acids. This chain will undergo several folds in a process called folding, where it will form a three-dimensional structure, the protein.
The right answer is D.
Mitochondria is a cellular cytoplasmic organelle that plays an essential role in respiratory and energetic phenomena. It is present in eukaryotic cells (with exception).
Plastids are plant organelles that often contain a pigment. This is the site of photosynthesis. It is present only in certain eukaryotes.
The fact that the mitochondria is better answered justifies the hypothesis that mitochondria have endosymbiosis before plastids.
