Select the best answer for the question.
8. what is the role of the enzyme primase in dna replication?
a. primase relaxes the dna double helix so that other enzymes can
reach the dna.
b. primase initializes replication by building short rna primers
complementary to the template.
c. primase is the enzyme that connects the ribosome to the dna.
d. primase seals any gaps between okazaki fragments or other
fragments of dna.

The correct answer will be option B (Making short RNA primers)

Explanation:

Primase is a RNA Polymerase enzyme involved in the replication of DNA in organisms. for e.g- Dna-G (Prokaryotes) or AEP (Archaeo-Eukaryote Primase).

Role of primase in replication

1.Primase enzymes are activated by Helicase and form primosome complex.

2. Primase then synthesizes primers- short RNA molecules from ss-template DNA of 4-15 nucleotides long.

3.These primers are recognised by the enzyme DNA polymerase  which adds and elonagte  by adding nucleotides to the primer.

thus, option B is correct.

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.
