You decide to move a human mitochondrial gene to the nuclear genome, placing it under the control of a nuclear promoter that causes constitutive transcription. Predict how the protein resulting from transcription of this gene in the nucleus and its translation in the cytoplasm will differ from this gene transcribed and translated in the mitochondria? Group of answer choices No protein will be made The resulting proteins would be identical The translated protein is likely to be shorter when transcribed and translated in the mitochondri

Is each of these statements true of chloroplast or mitochondrial genomes, both, or neither?a. contain tRNA genesb. encode proteins that participate in electron transport pathwaysc. all genes necessary for function of the organelleare presentd. vary greatly in size from organism to organism
The diagram below shows the structure of DNA from the level of a gene to a condensed mitotic chromosome. At each of the four locations marked, indicate how a gene may be regulated by selecting from the choices given. Some answer choices may fit into more than one position; however, you should use each answer choice only once. Choices given: Alternative splicing within the gene sequence can lead to different forms of mRNA. A promoter region can be blocked by another protein. Histone deacetylation can prevent DNA from unwinding. A regulatory region can be bound and increase transcription rates.
Yeast chromosome XII contains the HAP1 gene that contains codes to regulate proteins involved with cellular division. The SCM4 gene, on chromosome VII, produces membrane proteins and has a binding site for HAP1 in its promoter region. The diagram shows the location of the binding site for HAP1. Which of the following claims could scientists make regarding the interaction between HAP1 and SCM4? A - HAP1 would prevent translation of all SCM4 proteins by blocking the binding sections of messenger RNA and amino acids. B - HAP1 would decrease the translation of SCM4 proteins because promoter sections first bind transfer RNA and amino acids. C - HAP1 would stimulate transcription factors such as RNA polymerase and prevent all SCM4 proteins from beginning transcription. D - HAP1 would increase the transcription of SCM4 proteins because promoter sections bind RNA polymerase and initiate transcription.

You add a chemical to a cell that prevents all of the chromatin from uncoiling so that the chromosomes remain highly coiled, even after the completion of mitosis. If you add a transcription factor that triggers the transcription of mRNA for the protein Pitx in this situation what would happen. Group of answer choices A)All transcription of Pitx is stopped by the transcription factor B)Nothing because the Pitx gene is already being transcribed at the maximum ratea C)Nothing, because the Pitx gene cannot be transcribed in this highly coild state D)The amount of transcription of Pitx is greatly increasedt

The human mitochondrial genomes code for 37 genes but mitochondria produce only 13 proteins. What would most likely account for mitochondrial genomes having more genes than needed to code for the proteins produced? A. Several genes have been inactivated over evolutionary time and no longer code for proteins. B. Several genes are coded on both the top and bottom strands of DNA. Therefore, they code for the same proteins. C. Several genes code for products that are not translated. D. Several genes, and the proteins they code for, are of viral origin. They are not human mitochondrial genes.
Antibiotics such as chloramphenicol, tetracycline, and erythromycin inhibit protein synthesis in bacteria, but have no effect on the synthesis of proteins encoded by eukaryotic nuclear genes. Cycloheximide inhibits the synthesis of proteins encoded by nuclear genes, but has no effect on bacterial protein synthesis.
