Question 11.
Answer- Plasmid DNA
Plasmids are extra chromosomal DNA found in bacteria independent of genomic DNA. They help in surviving bacteria during harsh conditions and carry antibiotic resistance genes.

9. Different genes are located on different kinds of genetic elements - autosomes, W chromosomes, the mitochondrial genome, etc. Different elements are inherited in different ways, so different offspring inherit different elements from different parents. For each case, answer "both parents', 'mother', 'father, or 'neither parents. For instance, sons inherit autosomal genes from both parents, but sons inherit W chromosome genes from neither parent (because males are ZZ, and don't have a W chromosome...) (1 point per answer) Sons inherit...

Question 23 (1 point) The A and B alleles in ABO blood types can give rise to an individual that is blog type AB. This specific blood type is an example of: A) multiple alleles B) epistasis C) codominance D) partial dominance Imagine the gene encoding the lac repressor was mutated so that lactose (more technically allolactose) no longer bound to the repressor. However, the lac repressor was still capable of binding DNA at the operator sequence....

Question 12 (1 point) Which of the following conditions would kill amp' lac his bacteria? amp = ampicillin (an antibiotic), lac = lactose (a carbohydrate), his = histidine (an amino acid) A) growing the bacteria in media that contained ampicillin, had lactose as the sole metabolic carbon source, and contained the amino acid histidine. B) growing the bacteria in media that contained ampicillin, had lactose as the sole metabolic carbon source, but did not contain the...

genetics-gene mapping
Question 6 1 pts You identified 3 genes (A, B and C) located in the third chromosome of the Arabidopsis plant. After many crosses you determine the following genetic distances: A - 30- MU - B - 20 MU -C Out of the 500 hundred three point cross progeny you have found 10 double cross plants. Is there genetic interference happening? What is the coefficient of coincidence? I = 1 - c.o.c where c.o.c. = (observed DCO)/(expected DCO)...
