Mitochondria and chloroplasts have some of their own DNA. Their sequences are homologous with the DNA of some bacteria, which is evidence that supports the endosymbiont hypothesis. Answer and Explanation:1 Any time that DNA is copied, there is a chance that an error ...
Deoxyribonucleic acid (DNA) is a polymer of deoxyribonucleotides. Each deoxyribonucleotide consists of a deoxyribose sugar, a nitrogen base, and a phosphate group. The nucleotides are linked by phosphodiester bonds.Answer and Explanation: The negative charge of DNA is due to the phosphate groups ...

Since no protein involved in general DNA metabolism is present in the mitochondrial genome of Arabidopsis, gene expression in this organelle is under nuclear control. A consequence of this is that extensive anterograde (nucleus to organelle) and retrograde (organelle to nucleus) signalling is required...
DNA was extracted from saliva, and 15 single-nucleotide polymorphisms were analysed. Allele and genotype frequencies were related to the enamel loss of the specimens. Single-marker and haplotype analyses were performed using sex as a covariate. Mean enamel loss was higher for male donors than for...

DNA evidence is a trusted more than eye witness accounts for obvious reasons, but what downfalls occur with DNA forensics? Once DNA has been extracted from cells, how can it be used in the medical field? How is it used by forensic scientists?
Explain the process of DNA gel electrophoresis. How is this procedure used to analyze extracted DNA? DNA, because it has a ___ charge, moves to the ___ end of the field in gel electrophoresis; ___ DNA molecules migrate the most quickly. a. positive; posit...
