In which of the following ways are dna and mrna similar?
a) they are both always kept in the nucleus to keep them safe from damage.
b) they are both double stranded and must be unzipped during replication and transcription.
c) they both contain the entire genetic sequence of the original dna from their parent cell.
d) they both copy genetic code by forming a complementary sequence of nucleotides with an existing strand of dna.

Option (D).

Explanation:

DNA is present as a genetic material in all organisms except some viruses. DNA replication is the process of formation of copy of DNA molecule from the parental strand. Transcription is the process of formation of RNA molecules from the template DNA strand.

DNA and RNA copy the genetic code by the process of replication and transcription, respectively,  during which nucleotides complementary to the template DNA strands are added to the growing DNA or RNA chain.

Thus, the correct answer is option (D).

i am positive it is c. condensing but i may be wrong

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.
