1-Dont try to cram or spend more time here just read it fast and cover syllabus then practice MCQ's cheptor of same topic to check your progress. . |
2-Wrong options are also given but dont concentrate there, Right answer is in bold format. |

Q2 ⇒ In DNA sequencing, the primer specifies where the sequence begins [other wrong options] [Discuss in forum] specifies where the sequence ends both (a) and (b) generates variety of different sized fragments |
Q3 ⇒ The DNA that actually codes for a protein's primary structure in eukaryotes is portions of the gene called exons [other wrong options] [Discuss in forum] the entire gene portions of the gene called introns the promoter |
Q4 ⇒ RNA that is complementary to a segment of another RNA molecule to which it will bind is known as antisense RNA [other wrong options] [Discuss in forum] missense RNA nonsense RNA none of these |
