STRUCTURE OF RNA Q. 1 All of the following statements about Ribozymes are false, EXCEPT: A They are DNA molecules B They are not present in ribosomes C They plays a key role in RNA synthesis D They play a key role in post-transcriptional conversion of pre-mRNA to mature mRNA Q. 1 All of the […]
STRUCTURE OF RNA STRUCTURE OF RNA RNA is a polymer of ribonucleotides held together by 3’-5’ phosphodiester bridges. Sugar present in RNA is ribose. RNA contains uracil. RNA is a single stranded Mainly seen in cytoplasm. It does not obey Chargaff’s rule. Types of RNA- Messenger RNA (mRNA)- 5-10% Transfer RNA (tRNA)- 10-20% Ribosomal RNA
Structure of RNA Q. 1 The anticodon region is an important part of the A r-RNA B m-RNa C t-RNa D hn-RNa Q. 1 The anticodon region is an important part of the A r-RNA B m-RNa C t-RNa D hn-RNa Ans. C Explanation: C i.e. t – RNA Q. 2 About t-RNA, TRUE is:
Structure of RNA Introduction: RNA are unbranched polymeric molecules composed of nucleoside monophosphates joined together by phosphodiester bonds. They are considerably smaller than DNA. does not possess thymine except in rare cases. single-stranded and does not exhibit the equivalence of adenine with uracil and cytosine with guanine. “S” is the Svedberg unit, which is related to
