This will be relatively simple when studying conditions such as breast cancer, which occur in both sexes, but 99% of cases are women, or pregnancy states for obvious reasons. In contrast, coronary heart disease (CHD) is roughly equal between men and women between the ages of 40 and 59 ...
1). Clogging occurs when backed-up RNAPs occupy the promoter, blocking transcription initiation and reducing the rate of transcription (Sigurdsson et al. 2010; Washburn et al. 2003; Yuzenkova et al. 2014). This phenomenon is more likely to occur when the roadblock is strong, and when the ...

Is ribosomal RNA formed by transcription? What type of macromolecule is messenger RNA? What is the process of assembling a protein from RNA? Where would RNA polymerase attach? Why do cells need messenger RNA? Where does RNA polymerase begin transcribing a gene into mRNA?

During transcription, double-stranded DNA is transcribed into a complementary molecule of: a. single-stranded DNA. b. double-stranded DNA. c. single-stranded mRNA. d. single-stranded tRNA. If a section of double-stranded DNA contains 19 % Adenine, how much...
OK, so what does thereal datalook like? Here’s a plot for 20 years in the past and 20 years in the future, showing the actual days in each year when total and partial solar eclipses occur (the small dots everywhere indicatenew moons): ...
Guided by Holehouse's detective work, Powers went on to mutate certain ARFs so they would all make their way into the nucleus. They found that, as long as the ARFs can make it into the nucleus to bind DNA, when auxin is present, transcription will occur, no matter the cell type. ...
Although several studies have investigated the transcriptional changes that occur during sexual development and attempted to identify genes that may be involved, the molecular basis of sexual conversion has been elusive. Recent work has identified an apicomplexan-specific transcription factor as a key regu...
