$1.$ Large scale gene expression analysis can be done by: $$ Microarray $$ PCR $$ Sanger $$ Gel electrophoresis $2.$ Which of the following is not a future of DNA? o Base pairs joined by hydrogen bonds o Base unit is the nucleoside o Strands of complementary and anti$-$parallel o Sugar phosphate backbone $3.5-3$ patterns of sequence of DNA DNA strands are oriented in opposite directions, with one strand running from the $5\text{'}$ to $3\text{'}$ end and the complementary strand running from $3\text{'}$ to $5\text{'}.$ This orientation is crucial for processes like replication and transcription. $4.$ What is the intermediate between a gene and polypeptide? The intermediate is mRNA $($messenger RNA$),$ which is transcribed from DNA and then translated into a polypeptide. $5.$ Which of the following will play a role in structural support? $$ rRNA $$ mRNA $$ tRNA $$ bDNA $6.$ Which of the following is a secondary RNA structure? Secondary structure: the $2-$D analysis of the $[$hydrogen$]$ bonds between different parts of RNA. where RNA becomes double$-$stranded, where RNA f
