Assertion : In transcription only a segment of DNA and only one of the strands is copied into RNA. Reason : The process of replication, once set in, duplicates the total DNA os an organism.

Assertion (A): The newly formed mRNA has same sequence as the coding strand of transcriptional unit with uracil present at place of thymine. Reason (R): The rule of complementarity guides the formation of DNA and RNA.

Read the following statements A) In E .coli transcription and translation takes place in cytoplasm. (B) In humans,exons are interrupted by introns. (C) Introns are segment of DNA. (D) The principle of complementarity does not govern the process of transcription How many statements are incorrect?

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

Read the following statements carefully and choose the correct statements. A. In a transcription unit, the promoter located at the 5' end of coding strand B. The single strand DNA having the polarity 5' rarr 3' is the template strand C. RNA polymerase binds to the operator during transcription. D. Single base DNA differences occur in humans are called Single Nucleotide Polymorphism (SNPs).

Transcription I. IS the coping of a complementary mRNA on a DNA strand II. Requires a template, activated precursors, a divalent metal ion and RNA polymerase III. Is the first step in activation of amino acid IV. Directs the order of specific amino acids to form a polypeptide or protein
