Which of the following is the most accurate description of when gene expression is regulated in eukaryotic cells? question 15 options: a. regulation happens in many points along the process of the central dogma (genes to proteins). b. regulation only occurs at the time of transcription. c. regulation can not occur before proteins are made. d. regulation only happens during rna splicing.

The correct answer is first option A. Regulation happens at several points along the process of central dogma.

Central dogma is the the process of formation of mRNA from DNA and then the formation of proteins from the mRNA.

DNA -> mRNA -> Protein

The first process is transcription and the later is called translation. Regulation occurs at both the process. In fact, regulation is a process to turn certain genes on or off. Certain transcription factors bind to the regulatory region of a gene and regulate the rate of transcription. Processing of RNA and the rate of translation everything is regulated to take care of the amount of protein being formed/needed.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
