Read the following statements:
$A.$ Variation at genetic level arises due to mutations.
$B.$ Technique of $DNA$ fingerprinting was initially developed by Alec Jeffreys
Only $(B)$ is correct
Both $(A)$ and $(B)$ are correct
Only $(A)$ is correct
Both $(A)$ and $(B)$ are incorrect
$DNA$ generally acts as template for the synthesis of
Which of the following statements are correct?
$i. r-RNA$ provides the template for synthesis of proteins.
$ii.$$ t-RNA$ brings amino acids and reads the genetic code.
$iii. $$RNA$ polymerase binds to promoter and initiates transcription.
$iv. $A segment of $DNA$ coding for polypeptide is called intron.
Give scientific reasons : It is essential that $ tRNA$ binds to both amino acids and $mRNA$ codon during
protein synthesis.
Match List $I$ with List $II$:Choose the correct answer from the options given below :
List $I$ | List $II$ |
$A$ $RNA$ polymerase $III$ | $I$ snRNPs |
$B$ hline Termination of transcription | $II$ Promotor |
$C$ Splicing of Exons | $III$ Rho factor |
$D$ $TATA$ box | $IV$ SnRNAs, tRNA |
Consider the following
1.Structural gene
