In the
(b)
Interpretation:
The 5' and 3'ends should be labeled.
Concept Introduction:
In a phosphodiester bond, both DNA and RNA are formed by the link between the 3'-OH (3 end) group of one nucleotide and the 5'-phosphate (5 end) of a second nucleotide
(c)
Interpretation:
Three- or four-letter abbreviation for the two nucleotides needs to be determined.
Concept Introduction:
Nucleotides are repeating monomers units present in the nucleic acid. There are two types of nucleotide namely DNA and RNA.
(d)
Interpretation:
Whether the given molecule is ribonucleotide or deoxyribonucleotide should be explained.
Concept Introduction:
Nucleic acids are consisting of repeating monomers called nucleotides.
There are two types of nucleotides. They are DNA and RNA. Nucleic acids are composed of monomers called nucleotides.
(e)
Interpretation:
The dinucleotide should be named.
Concept Introduction:
Nucleic acids are consisting of repeating monomers called nucleotides.
There are two types of nucleotides. They are DNA and RNA. Nucleic acids are composed of monomers called nucleotides.
The name of the dinucleotide begins with the nucleotide with the 5' end.

- a Describe the three components of a nucleotide. b How does the structure of an RNA nucleotide differ from that of a DNA nucleotide?arrow_forwardThere are 41 = 4 mononucleotides of DNA, there are 42 = 16 possible dinucleotides, and so on. If a segment of DNA were completely random, how many nucleotides long would it need to be in order to have one possible sequence for each person on Earth (currently about 7.5 billion people)?arrow_forwardIf a codon consists of two nucleotides, how many codons would be possible? Would this be a workable code for the purpose of protein synthesis?arrow_forward
- The base sequences in mRNA that code for certain amino acids are Glu: GAA, GAG Val: GUU, GUC, GUA, GUG Met: AUG Trp: UGG Phe: UUU, UUC Asp: GAU, GAC These sequences are complementary to the sequences in DNA. a. Give the corresponding sequences in DNA for the amino acids listed above. b. Give a DNA sequence that would code for the peptide trp-glu-phe-met. c. How many different DNA sequences can code for the tetrapeptide in part b? d. What is the peptide that is produced from the DNA sequence TACCTGAAG? e. What other DNA sequences would yield the same tripeptide as in part d?arrow_forwardMust the ratio of guanine to cytosine be 1:1 in RNA? Explain.arrow_forwardWhat codons code for each amino acid? a. glycine b. isoleucine c. lysine d. glutamic acidarrow_forward

For keyboard navigation, use the up/down arrow keys to select an answer. phosphate b. base sulfate saccharidearrow_forwardWhich statement about RNA and DNA is incorrect? O a. The bases adenine, guanine and cytosine are found in both RNA and DNA. Ob. The carbohydrates in nucleic acids are ribose in RNA and 2-deoxyribose in DNA. O c. In both RNA and DNA, guanine and cytosine always pair by forming one hydrogen bond. Od. In DNA adenine and thymine always pair by forming two hydrogen bonds Oe. The fourth base is uracil in RNA and thymine in DNA.arrow_forward2arrow_forward
