How many nucleotides define one codon for one amino acid? If a DNA sequence is TCCGAATGC, what is its complimentary DNA strand and RNA strand? What is the DNA structure of eukaryotic cells? Suppose a 100-base-pair, double-stranded DNA molecule consists of 23% cytosine bases. How many tot...
During transcription, how many RNA nucleotide bases would usually be encoded by a sequence of 99 DNA nucleotide bases? a) 297 b) 99 c) 33 d) 11 e) The answer is impossible to determine with the information given. How many nucleotides on mRNA code for one amino acid, and what...
Shared intron position was highly predictive of sequence similarity in the case of CeHD-5 and -7 and in the case of CeHD-9,-13, and -22. The library is currently being exhaustively screened, and the genes are being mapped to the Cambridge YAC polytene grids (many thanks to Alan Coulson...
In order to provide a sequence, Sanger sequencing makes use of chemical analogs of the nucleotide bases. The analogs, called dideoxyribonucleotides (ddNTPs), are missing the hydroxyl group that is required for extension of a DNA polynucleotide chain....
To determine how many base pairs in the gene are needed to code for the enzyme lysozyme, which contains 129 amino acids, we can follow these steps: Step 1: Understand the coding relationship between amino acids and base pairs.- Each amino acid is coded by a sequence of three nucleotide b...
DNA is so important that the United States government has spent enormous amounts of money to sequence DNA in the human genome in hopes of understanding and finding cures for many genetic diseases. Finally, from the DNA of one cell, we can clone an animal, a plant or perhaps even a human...
coli), leads to the recognition of mismatch bases in the “daughter” strand and creates an incision at specific sites up to 1kb from the mismatch base. Exonucleases remove the part of the DNA from the incision to the mismatch, allowing DNA polymerase d (Polymerase III in prokaryotes) to ...
How many genes does the Human Genome contain? The Human Genome Project has revealed that there are probably about 20,000-25,000 'haploid' protein coding genes. The completed human sequence can now identify their locations. But only about 1.5% of the genome codes for proteins, while the rest...
Data, 0 or 1, was represented by a short piece of single-stranded DNA, called an oligonucleotide, that contained a series of bases: adenine, thymine, guanine and cytosine. (In nature, the sequence of bases codes for a gene.) For example, two inputs of 1 (DNA strands 1 and 2) would...
"Short palindromic repeats" refers to sequences that read the same forward and backward, like the words "kayak" and "racecar."DNAconsists of two paired strands twisted around each other in a helix. A DNA palindrome thus refers to a string of DNA letters, or bases — A (adenine), C (...
