- What part(s) of a nucleotide (namely, phosphate, sugar, and/or base) is/are found in the major and minor grooves of double-stranded DNA, and what part(s) is/are found in the DNA backbone? If a DNA-binding protein does not recognize a specific nucleotide sequence, do you expect that it binds tothe major groove, the minor groove, or the DNA backbone? Explain.arrow_forwardIf the DNA sequence A-T-T-G-G-C-C-T-A on an informational strand mutated and became A-C-T-G-G-C-C-T-A, what effect would the mutation have on the sequence of the protein produced?arrow_forwardIn the DNA double-helix structure, the larger of the two grooves formed by the helical twist where certain base pairs are exposed is called the:arrow_forward
- Spontaneous deamination of cytosine bases in DNA takes place at low but measurable frequency. Cytosine is converted into uracil by loss of its amino group. After this conversion, which base pair occupies this position in each of the daughter strands resulting from one round of replication? Two rounds of replication? (a) How many different 8-mer sequences of DNA are there? (Hint: There are 16 possible dinucleotides and 64 possible trinucleotides.) We can quantify the information- carrying capacity of nucleic acids in the following way. Each position can be one of four bases, corresponding to two bits of information (2² = 4). Thus, a chain of 5100 nucleotides corresponds to 2 × 5100 = 10,200 bits, or 1275 bytes (1 byte =8 bits). (b) How many bits of information are stored in an 8-mer DNA sequence? In the E. coli genome? In the human genome? (c) Compare each of these values with the amount of information that can be stored on a computer compact disc, or CD (about 700 megabytes).arrow_forwardWhat is the name of the enzyme that add nucleotides to a growing DNA strand? What kind of bonds does this enzyme form between the nucleotides?arrow_forwardIn NOT more than 200 words, explain how the double-helical structure of DNA suggests a mechanism for DNA replication?arrow_forward
