Antisense RNA used for silencing a ceellular mRNA in RNAi has sequence complementary to antisense strand of mRNA.

Which of these statements about protein synthesis are NOT correct ? I. During transcription, mRNA synthesized from DNA nucleotides to have the same sequence of nucleotides as the DNA strand on which it was made. II. During transcription , tRNA is synthesized from RNA nucleotides and carries codons that are complementary to the sequence of nucleotides on the DNA strand on which it was made. III. During translation, mRNA is synthesized from RNA nucleotides to have the complementary sequence of nucleotides to that. Of the DNA strand on which it was made . IV. During translation ribosomes move on mRNA from '5' and '3' one codon at a time .This is called translocation

By producing complementary strand for the transcribed mANA results in making ds - mRNA which cannot be translated . Thus leading to silencing of the mRNA. This technique has proved to be beneficial for controlling nematode infection and increasing the yield n
