The amino acid sequences of a yeast protein and a human protein having the same function are found to be 60% identical. However, the corresponding DNA sequences are only 45% identical. Account for this differing degree of identity.
The human genome has approximately 30,000 genes, but human cells can produce over 100,000 different polypeptides. Explain how this is possible
The genetic information contained in DNA consists of a linear sequence of coding units known as codons. Each codon consists of three adjacent DNA nucleotides that corresponto a single amino acid in a protien.
The E.coli DNA molecule contains 4.70 x 10^6 base pairs. Determine the number of codons that can be present.
Assuming that the average protein in E.coli consists of a chain of 400 amino acids, calculate the maximum number of protiens that can be coded by an E.coli DNA molecule.

- A lilP mutant called lilPXS is isolated that produces a truncated polypeptide of only 6 AA in length. Describe a single basepair DNA change that would lead to this truncated version of the protein. Multiple options are possible（100 words maximum）arrow_forwardTo hold bacterial DNA in a more compact configuration, specificproteins must bind to the DNA and stabilize its conformation.Several different proteins are involved in this process.

- Below is a sequence of 540 bases from a genome. What information would you use to find the beginnings and ends of open reading frames? How many open reading frames can you find in this sequence? Which open reading frame is likely to represent a protein- coding sequence, and why? Which are probably not functioning protein-coding sequences, and why? Note: for simplicitys sake, analyze only this one strand of the DNA double helix, reading from left to right, so you will only be analyzing three of the six reading frames shown in Figure 19.4.arrow_forwardState the properties of the WatsonCrick model of DNA in the following categories: a. number of polynucleotide chains b. polarity (running in same direction or opposite directions) c. bases on interior or exterior of molecule d. sugar/phosphate on interior or exterior of molecule e. which bases pair with which f. right- or left-handed helixarrow_forwardConsider the following DNA sequence, which codes for a short polypeptide: 5'-ATGGGCTTAGCGTAGGTTAGT-3' Determine the mRNA transcript of this sequence. You have to write these sequences from the 5' end to the 3' end and indicate those ends as shown in the original sequence in order to get the full mark.

- Within living cells, many different proteins play importantfunctional roles by binding to DNA. Some proteins bind to DNA butnot in a sequence-specific manner. For example, histones are proteinsimportant in the formation of chromosome structure. The positivelycharged histone proteins bind to the negatively charged phosphategroups in DNA. In addition, several other proteins interact with DNAbut do not require a specific nucleotide sequence to carry out theirfunction. For example, DNA polymerase, which catalyzes thesynthesis of new DNA strands, does not bind to DNA in a sequencedependentmanner. By comparison, many other proteins do interactwith nucleic acids in a sequence-dependent fashion. This means that a specific sequence of bases can provide a structure that isrecognized by a particular protein.Someexamples include transcription factors that affect the rate oftranscription and proteins that bind to origins of replication inbacteria.What topic in genetics does this question address?arrow_forwardWithin living cells, many different proteins play importantfunctional roles by binding to DNA.
