the-human-gene-for-82-lens-crystallin-has-the-components-listed-below-the-numbers-represent-nucleoti-18441

The human gene for 82 lens crystallin has the components listed below. The numbers represent nucleotide pairs that make up the particular component. Assume for simplicity that no alternative splicing is involved. $$\begin{array}{lr} 5^{\prime} \text { UTR } & 174 \\ \text { 1st exon } & 119 \\ \text { 1st intron } & 532 \\ \text { 2nd exon } & 337 \\ \text { 2nd intron } & 1431 \\ \text { 3rd exon } & 208 \\ \text { 3rd intron } & 380 \\ \text { 4th exon } & 444 \\ \text { 4th intron } & 99 \\ \text { 5th exon } & 546 \\ \text { 3' UTR } & 715 \end{array}$$ Answer the following questions about the 82 lens crystallin gene, primary transcript, and gene product. Questions asking where should be answered with one of the 11 components from the list or with None. Assume poly-A tails contain 150 As. a. How large is the 82 lens crystallin gene in bp (base pairs)? b. How large is the primary transcript for 82 lens crystallin in bases? c. How large is the mature mRNA for $B 2$ lens crystallin in bases? d. Where would you find the base pairs encoding the initiation codon? e. Where would you find the base pairs encoding the stop codon? f. Where would you find the base pairs encoding the $5^{\prime} \operatorname{cap} ?$ g. Where would you find the base pairs that constitute the promoter? h. Which intron interrupts the $3^{\prime}$ UTR? i. Where would you find the sequences encoding the $\mathrm{C}$ terminus? j. Where would you find the sequence encoding the poly-A tail? k. How large is the coding region of the gene in bp (base pairs)? 1. How many amino acids are in the $B 2$ lens crystallin protein? $\mathrm{m} .$ Which intron interrupts a codon? n. Which intron is located between codons? o. Where would you be likely to find the site specifying poly-A addition? You find in lens-forming cells from several different people small amounts of a polypeptide that has the same $\mathrm{N}$ terminus as the normal $\mathrm{B}$ lens crystallin, but it has a different $C$ terminus. The polypeptide is 114 amino acids long, of which 94 are shared with the normal protein and 20 are unrelated junk. No mutation is involved in the production of this 114 -amino acid protein. p. Outline a hypothesis for the process that would produce this protein. Your hypothesis should explain why 94 amino acids are the same as in the normal 82 lens crystallin. q. Explain why you would expect that a polypeptide such as the 114 -mer described above would on average have 20 amino acids of junk.

In order for a gene to be expressed, it must be transcribed into RNA, which is done by RNA polymerase. RNA polymerase resembles DNA polymerase because they both use a single strand of DNA as their template, they both need a pool of nucleoside triphosphates to incorporate into the growing nucleic acid strand, and they both always synthesize nucleic acids in the 5’ to 3’ direction (both read their DNA template strands in the 3’ to 5’ direction). They differ in a few ways too. RNA polymerase synthesizes RNA using nucleoside triphosphates, while DNA polymerase synthesizes DNA using deoxynucleoside triphosphates; in RNA, uridine is substituted for thymidine. The final product of RNA polymerase is single-stranded, while DNA is famously double-stranded, so that the new strand synthesized by DNA polymerase remains base-paired to its complementary template strand. Another difference is where synthesis begins: DNA replication begins at origins of replication, while transcription begins at promoters. To a first approximation, a promoter is a region of DNA with a sequence that is recognized by proteins which can bind to it, thereby recruiting RNA polymerase. A promoter is a stretch of DNA which says to RNA polymerase "start transcription here". Finally, unlike DNA polymerase, RNA polymerase is able to unwind DNA on its own to create a short region of single-stranded DNA to use as a template, and it does not require a double-stranded region to elongate: in other words, it can add the first few complementary RNA nucleotides all by itself. We will first consider transcription in the bacterium E. coli (a prokaryote). Promoters in E. coli (and also in eukaryotes) do not have an exact fixed DNA sequence, but they do often have a consensus sequence: in other words, a favored nucleotide for each position. In general, the closer a promoter adheres to the consensus sequence, the "stronger" a promoter it will be: transcription initiates more often at a strong promoter than at a weak one, leading to the production of more RNA. A promoter in E. coli usually has 2 small blocks of consensus sequence separated by 15-19 random nucleotides: the first has a consensus sequence of TTGACA and the second has a consensus sequence of TATAAT, with the preferred spacing being 17 nucleotides. As is always the case, the DNA sequence is given in the 5’ to 3’ direction (unless otherwise noted). Remember that DNA is double-stranded: it is also conventional to give the DNA sequence of only one strand, generally NOT the template strand (the one which is actually being "read" by RNA polymerase), but instead the one that will most closely resemble the RNA product of transcription, which is variously referred to as the sense strand, coding strand, or RNA-like strand. Promoters are directional, in that the way they are oriented sends RNA polymerase off in the correct direction to transcribe the gene, which is thus referred to as being "downstream". The first consensus sequence is called the "-35 element" because the beginning of it lies about 35 nucleotides upstream of where RNA polymerase will place the first RNA nucleotide (the "+1" position); the second consensus sequence is correspondingly called the "-10 element" because the beginning of it lies about 10 nucleotides upstream of where transcription begins. a. Draw a double-stranded region of DNA containing a promoter in the space below; for the regions outside the promoter, you can just use double lines as before, but within the promoter use the consensus sequence of bases. Use "N" for the unspecified nucleotides in the spacer region, and also in the region downstream of the -10 element until you reach the first nucleotide that will be incorporated into RNA, which should be designated with an "X". NB: there is no "0" position; counting goes straight from -1 to +1. Your drawing should look something like this: -----------------NNNX------------------ -----------------NNNX------------------ Be sure to label the 5’ and 3’ ends of each strand, and provide the correct complementary sequence for the consensus sequences.

as-a-result-of-a-substitution-mutation-a-normal-dna-base-triplet-3-atc-5-is-charged-to-3-act-5-describe-specifically-what-effect-this-would-have-on-the-resulting-protein-use-your-codon-sheet-02627

As a result of a substitution mutation, a normal DNA base triplet 3’ ATC 5’ is changed to 3’ ACT 5’. Describe specifically what effect this would have on the resulting protein. (Use your codon sheet, Fig. 6 in the transcription and the translation sections.) This would be a nonsense mutation that would prematurely terminate the protein. Both ATC and ACT are transcribed into stop codons. This would be a missense mutation resulting in one wrong amino acid in the protein. 6. What is the function of a peptide bond? A peptide bond joins the amino group of one amino acid to the carboxy group of another amino acid. 7. Which of the following DOES NOT describe transcription? Synthesis of RNA occurs. Complementary base pairing occurs. Complementary copying of a portion of one strand of DNA occurs. tRNA carries amino acids to the ribosomes. The enzyme RNA polymerase is involved. 8. Which one of the following describes a DNA nucleotide? A nitrogenous base, a molecule of deoxyribose, and a phosphate molecule. 9. As a result of a substitution mutation, a normal DNA base triplet 3’ ATC 5’ is changed to 3’ ACT 5’. Describe specifically what effect this would have on the resulting protein. (Use your codon sheet, Fig. 6 in the transcription and the translation sections.) This would be a nonsense mutation that would prematurely terminate the protein. This would be a sense mutation resulting in no change to the final protein. The protein ATC codes for the amino acid lle. ACT codes for the amino acid Thr. 10. Which one of the following describes the function of mRNA during Bacterial protein synthesis? mRNA is made complementary to a gene in the DNA. mRNA consists of the series of codons that determines the amino acid sequence of a polypeptide or protein. 11. The sequence of anticodons along a gene ultimately determines the order of amino acids in proteins.
