. Sugar utilized in RNA is ribose sugar. Ribosomal RNA is a component of the ribosomes. The molecules of RNA are smaller and found outside of the nucleus in the cytoplasm.

Work by John Sutherland and others demonstrated that RNA could form spontaneously. The RNA exists as a single-stranded molecule. Messenger RNA carries copies of instructions for assembling proteins from DNA to the ribosomes.

Any of various nucleic acids that contain ribose and uracil as structural components and are associated with the control of cellular chemical activities is called also ribonucleic acid. CIn eukaryotes transcription takes place in the cytoplasm and requires many enzymes. Ribozymes may function in RNA splicing.

Which of the following statements about RNA is not correct. Science Biology QA Library Which of the following is true about RNA synthesisa Synthesis of RNA is always in the 5 to 3 directionb RNA polymerase requires a primer for initiating transcriptionc U is inserted opposite T in transcriptiond New nucleotides are added on the 2-OH of the ribose sugar. Check out a sample QA here.

The sigma factor is associated with RNA polymerase during elongation and termination. Biology questions and answers. Ribose nucleic acid RNA is a single strand or chain which is formed by the end to end polymerization of a number of ribonucleotides.

The C-terminus of the RNA polymerase must be phosphorylated for RNA synthesis to begin. A It is a site for active ribosomal RNA synthesis. Translation can only occur after transcription termination.

B it is a membrane-bound structure. The correct option is A i and iii Viruses are the smallest among all microorganisms. ARNA editing removes the exons from pre-mRNA leaving only the introns in the final molecule.

RNA stands for the ribonucleic acid and the DNA is deoxyribonucleic acid. Ribonucleic acid RNA - Made up of nucleotides consisting of pentose sugar which is ribose Phosphoric acid and bases Adenine Guanine cytosine and uracil - RNA hence has a double stranded -helix structure. Which of the following statements is not true about RNA.

In most cases RNA is single-stranded and not produced complementary base pairing because it is single-stranded. The DNA has a deoxy sugar in the nucleotideDNA and RNA differ in the size. Which of the following is true.

Which of the following statements about gene expression is falsea More than one RNA polymerase can be transcribing a specific gene at a given timeb More than one ribosome can be translating a specific transcript at a given timec Translation begins at a site called a promoterd Transcription stops at a site called a terminatore Some amino acids are coded for by more. Share It On Facebook Twitter Email. C larger nucleoli are present in dividing cells.

Environmental factors such as minerals and temperature are thought to have played key roles in the evolution of the first cells. Which of the following is not true of RNA processing. Structure is always important to function in all organic molecules.

Except option b all the given statement is true about the RNA Ribonucleic acid. A It is primarily double-stranded B It has a phosphate and deoxyribose backbone C It has the same purine bases as DNA but differences in the pyrimidine base usage D It is primarily short with simple and random structure E None of the above 2. Which of the following is true about RNA.

RNA or ribonucleic acid is the genetic material of many organisms like viruses. Transfer RNA carries amino acids to the ribosomes for assembly into proteins. All the types of RNA polymerase transcribes different RNAs.

Neither DNA or RNA contain uracil C. It consists of nucleotides that are composed of 3 elements particularly sugar molecules element bases and phosphate. Viruses consist of a genetic material DNA or RNA enclosed within a protein coat.

RNA stands for ribonucleic acid it contains the ribose sugar and has 4 base pairs of adenine guanine cytosine and uracil. RNA contains uracil D. Because RNA has a single helix structure whereas DNA has a double helix structure.

The correct option is A RNA synthesis is always in the 5 3 directionIn transcription as in DNA replication nucleotides are added on to the 3 OH of the g. A It is a site for active ribosomal RNA synthesis. Explore related topics on NEET at BYJUS.

RNA contains uracil D. Want to see the full answer. Which of the following is true of transcription.

2-each strand of the double helix serves as a template fro synthesis of a new complementary strand of DNA one old strand makes two new strands 3- DNA enzyme use each strand as a template to assemble new complementary strands of DNA from free nucleotides- DNA enzymes seal any. Neither DNA or RNA contain uracil C. D it takes part in spindle formation.

Thus the option B and D are true statements about RNA. The DNA has the genetic code which makes the RNA and RNA contain the code to make the primary sequence of the amino acid to make proteins. DNA contains uracil Expert Solution.

One of the types of RNA polymerase transcribes hnRNAs be it I II or III. Both DNA and RNA contain uracil B. Transcription is the process by which the information stored in the strand of DNA gets copied into a new molecule of mRNA which is messenger RNA.

RNA is involved in protein synthesis but in some viruses it also serves as genetic material. Which Of The Following Is True For Nucleolus. Both DNA and RNA contain uracil B.

DNA and RNA are chemically similar except the nature of sugar. Nucleotides may be added at both ends of the RNA. Choose the correct answer from the alternatives given.

Viruses lack a cellular framework and need the host cell to multiply reproduce. Which of the following is true of prokaryotic transcription. Because double stranded structure always belong to DNA -helix structure belongs to the secondary structure of proteins.

RNA splicing can be catalyzed by spliceosomes. 1- a cell replicates its DNA before it divides cells divide and need an exact copy of DNA. Check out a sample QA here.
