14. A restriction enzyme (for example BamH1): (2 points) a. Is a specific sequence of DNA b. Can be used to ligate DNA ends C. Recognizes palindromic DNA sequences d. Cuts random sequences of DNA
Write true or false ______ 1. The DNA sequence of one human being is on average 99.9% identical to another random human being. ______ 2. As of 2009, all living human beings have had their entire genome sequenced. ______ 3. The nucleotide bases present in a DNA sequence are A, U, G, C. ______ 4. Techniques that enabled scientists to clone genes were developed in the 1970s. ______ 5. A restriction enzyme is useful because it is a generic enzyme...
In a viral genome that is 10,000 bases long, C and G occure with a frequency of 1/3 and A and T occure with a frequency of 1/6. What is the expected number of occurences of the sequence ACGT assuming multinomial.i.i.d model for genome?
3.13 pts) The restriction enzyme known as Notl recognizes the following sequence: 5-GCGGCCGC-3 3-CGCCGGCG-5 However, if the cytosines in this sequence have been methylated. NotI will not cleave the DNA at this site. For this reason, Net is commonly used to investigate the methylation state of CpG islands. A researcher has studied a gene, which we will call T. that is found in com, and encodes a transporter involved in the uptake of phosphate from the soil. A CpG island...
2. The following sequence is a wild-type gene that encodes a tRNA-his molecule that recognizes the codon 5- CAU-3' on all mRNAs in the bacterial cell. The sequence given is from the point where transcription starts (called "+1") to the point where transcription ends (called the "terminator"). 5'-CCCGTTGCTCAGATCTGGATATCCTTCCTGCATAGAATCGCTTGCTGAAGCTGATACGCGCAACGGT-3' 3'-GGGCAACGAGTCTAGACCTATAGGAAGGACGTATCTTAGCGAACGACTTCGACTATGCGCGTTGCCA-5' a. Which strand (the upper or the lower) is used as the template in transcription? UNDERLINE THE CORRECT CHOICE b. Write out the amino acid sequence the protein, if any, that...
Which of the following restriction endonucleases produces 3' overhangs? (position where the enzyme cuts is indicated by an arrow) A. EcoRI (5'-G↓AATTC-3') B. HindIII (5'-A↓AGCTT-3') C. EcoRV (5'-GAT↓ATC-3') D. PstI (5'-CTGCA↓G-3')
6. Consider the enzyme HindIII cutting a DNA molecule of 40% GC a) What sequence does this enzyme recognise? b) What proportion of this DNA is made up of adenine bases? c) How often would HindIII cut this molecule (in bp)? d) If this DNA molecule was 21,000 bp in length, how many fragments would be produced on average? Could you please explain your reasoning for the answers so that i may actually understand it. so far I know HindIII enzyme recognises AAGCTT, but...
9. In many cases where a sequence of random variables converges in probability to some b, this b will be either the expected value or the limit of the expected values of the variables. However, this is not generally true. (a) Consider a sequence of random variables where for each n, xn comes from this distribution with P(Xn = n) = 1/n and P(Xn = 0) = 1 - 1/n. Find limn+ E(Xn). (b) Find the value b such that...
If one strand of DNA has the sequence C-T-A-C-C-G-T-T-A, what sequence would appear opposite it on the other strand? Enter the complementary sequence of letters separated by hyphens.
The bacterium Thermus thermophilus was first isolated from hot springs in Japan, living in an environment with an average temperature of 68 degree C (154 degree F). This temperature would kill you, but these organisms are adapted to it. One of the adaptations to this lifestyle includes DNA that is 70% G-C base pairs, one of the more extreme departures from the average 50%. The chromosome is about 2.13 times 10^6 bp in length, quite normal for a bacterial species....
