Match column with column II and select the correct option from the given codes. Column I Column II A. Translation (i) Aminoacyl tRNA synthetase B. Transcription (ii) Okazaki fragments C. DNA replication (iii) RNA polymerase
Translation requires the Aminoacyl-tRNA synthetases to catalyze aminoacylation of tRNAs by joining an amino acid to its cognate tRNA.The charged aminoacyl tRNA is readily protected by a protein that is very abundant in the cell and that carries the tRNA to the ribosome. Transcription is the process of the DNA coding for an mRNA with the help of the DNA dependent RNA polymerase enzyme. It forms a single stranded mRNA from the template of DNA. DNA replication happens bidirectionally and involves both the leading strand and lagging strand synthesis and the latter is characterized by the formation of okazaki fragments that are short segments of DNA that are synthesized discontinuously and later linked together by the enzyme DNA ligase to create the lagging strand during DNA replication.
So, the correct option is 'A-(i), B-(iii), C-(ii)'.
Which of the statements about denaturation has given below are correct? (a) Denaturation of proteins causes loss of secondary and tertiary structures of the protein. (b) Denaturation leads to the conversion of the double strand of DNA into the single strand. (c) Denaturation affects primary structure which gets distorted.
List two essential roles of ribosome during translation.
During translation, activated amino acids get linked to (RNA). This process is commonly called as
In a mRNA molecule, untranslated regions (UTRs) are present at
AUG codon is an
