Why do different cells synthesize the same protein if their genetic code is identical? If DNA in all cells is identical, how can a kidney cell be different (do a different job) from a thyroid cell? How are chromatin, chromosomes, and DNA related? How do the different DNA nucleotides...
Four of these clones were real U3 snRNA genes because they were transcribed in frog oocytes and the DNA sequences corresponding to the U3 snRNA were identical to the U3 snRNA of HeLa cells. The nucleotide sequences of four true U3 snRNA genes, 537 nucleotides on the 5′-flanking region ...
The LTRs are identical and exhibit the following features: a terminal inverted 6-bp repeat, a Goldberg–Hogness (TATAAA) sequence, sequences which have been implicated in polyadenylation and the termination of transcription, and an open reading frame. The open reading frame of the R-LTR starts...
Let g(n) be the length of a longest binary string containing at most n distinct squares (two identical adjacent substrings). Then g(0) = 3 (010 is such a string), g(1) = 7 (0001000) and g(2) = 18 (010011000111001101). How does the sequence \\Phi g(n) \\Psi behave? We ...
38 To identify mRNA sequences shared by sEV-enriched isoforms, we conducted bioinformatic analysis in the MEME Suite39 on 928 sEV-enriched isoforms. A tool called STREME40 was used to discover motifs ab initio and identified 42 significantly enriched 8–15 base pair sequences (Figure 5A; Table...
sequencedneffrom several positive MDM and CD4 QVOA wells from participant CP36. Thenefsequences from the two positive MDM wells were identical but all CD4nefsequences were distinct. Although this does not indicate clonality on the part of MDMs, as it is only a fraction of the full viral ...

How many 8 elements DNA sequences - Do not end with C or T? - Start with A and ends with T? How many strings over the alphabet (a, b, c, d, e) of length 13 have exactly four (4) c's? Let S = {0, 1, 2, 3, 4, ...}, A ...
1995. The N-terminal sequence (TKLGXLRLXYE) of an unidentified RER membrane protein (Görlich et al., 1992) is identical to the predicted N terminus of STT3-A following removal of the initiator methionine, hence STT3-A has an uncleaved signal sequence that serves as the first of 13 ...
Another method for preparing a mutated nucleic acid sequence according to the invention, and the corresponding protein, consists in carrying out a random mutagenesis of short target DNA sequences via PCR with degenerate oligonucleotides, or by <<doping>> each of the four nucleosides involved in the...
