RNA

• What is the main topic of the video?

  Structure of RNA and its function
• What is RNA classified as?

  A polymer
• What is the monomer that makes up RNA?

  A nucleotide
• What type of sugar is found in RNA?

  Ribose sugar
• How many carbons does ribose sugar contain?

  Five carbons
• What are the four possible nitrogenous bases in RNA?

  Adenine, guanine, cytosine, uracil
• What is the phosphate group in RNA?

  One phosphate group
• How does RNA differ from DNA in terms of sugar?

  RNA contains ribose, DNA contains deoxyribose
• What nitrogenous base does RNA have instead of thymine?

  Uracil
• What is the general function of RNA?

  To copy and transfer genetic information
• What are the three types of RNA?

  mRNA, tRNA, rRNA
• What does mRNA stand for?

  Messenger RNA
• What is the role of mRNA in protein synthesis?

  It is a copy of one gene from DNA
• Why can mRNA leave the nucleus?

  It is shorter than DNA
• How long does mRNA typically exist?

  Short-lived
• What does a codon on mRNA represent?

  Three bases coding for one amino acid
• What shape does tRNA take?

  Cloverleaf shape
• What holds the cloverleaf shape of tRNA in place?

  Hydrogen bonds
• What is the function of tRNA?

  To transfer amino acids
• How does tRNA attach to mRNA?

  Through complementary base pairing
• What does rRNA stand for?

  Ribosomal RNA
• What is the function of rRNA?

  Combines with protein to make ribosomes
• What are the differences between RNA and DNA?

  Differences in monomers:

  • RNA contains uracil; DNA contains thymine
  • RNA has ribose; DNA has deoxyribose

  
  

  Differences in polymers:

  • RNA is shorter than DNA
  • RNA is single-stranded; DNA is double-stranded
• Why is DNA much larger than RNA?

  DNA contains all genes; RNA is a copy
• What is the structure of RNA compared to DNA?

  RNA is single-stranded; DNA is double-stranded
• What does the 'r' in RNA represent?

  Ribose
• What is the role of ribosomes in protein synthesis?

  They facilitate the assembly of amino acids
• What happens to mRNA after it codes for a protein?

  It gets degraded
• Why can't DNA leave the nucleus?

  It is too large to exit
• What is the significance of codons in mRNA?

  They determine specific amino acids
• What is the primary purpose of the video?

  To explain RNA structure and function
