[ 1 ] Between 5% and 42% of women seen for ultrasound assessment with a positive pregnancy test have a pregnancy of unknown location, that is a positive pregnancy test ...
Although ectopic expression can be caused by a natural condition, [1] it is uncommonly seen in nature because it is a product of defects in gene regulation. In fact, ectopic expression is more commonly used for research purposes. Artificially induced gene expression helps to determine the function of a gene of interest.
Ectopic recombination is typically mediated by sequence similarity at the duplicate breakpoints, which form direct repeats. Repetitive genetic elements such as transposable elements offer one source of repetitive DNA that can facilitate recombination, and they are often found at duplication breakpoints in plants and mammals.

An ectopic pregnancy is a common complication that can be life-threatening to the mother if left untreated. Here's what you need to know.
Hyperemesis gravidarum, which is a severe form of nausea and vomiting of pregnancy can lead to nutritional deficiencies, weight loss, electrolytes imbalance and is one of the leading causes of hospitalization in the first trimester of pregnancy. [36] Constipation is another GI symptom that is commonly encountered during pregnancy. It is ...
With ectopic pregnancies back in the news, here's what you need to know.
Ectopic recombination can occur during both meiosis and mitosis, although it is more likely occur during meiosis. [3] It occurs relatively frequently—in at least one yeast species (Saccharomyces cerevisiae) the frequency of ectopic recombination is roughly on par with that of allelic (or traditional) recombination.
