mRNA is formed with the help of ribose sugar residues where the nitrogenous bases are associated. All the nucleotides are attached with the phosphodiester linkage but the sugar is different at a single residue from that of a DNA. The structure is single-stranded and the resultant formation of m...
How do the bases of RNA differ from bases of DNA? A DNA strand has the code ATG. What would the complementary sequence mRNA stand have? What are the complementary base pairs that form in DNA? A) A - U and G - C B) A - T and G - C C) A - G...
Glycosylases travel along and flip the bases of each DNA strand in order to evaluate the status of each base pair. If a faulty base is detected, it is removed, and an AP endonuclease cuts the phosphodiester backbone. DNA polymerase will subsequently fill in the correct nucleotide. This ...
For example, if one strand reads "GATC" in one direction, these DNA bases will pair up with "CTAG" on the opposite strand because G always pairs with C and A always pairs with T. When read backward, CTAG becomes the original sequence, GATC. These repeats are "regularly interspaced," me...
Newly developed gene-editing tools aim to overcome the limitations of the CRISPR/Cas9 platform. Base editing, for example, is a highly precise method that allows programmable alterations to single DNA bases. Currently, three types of base editors are available: CBEs that convert C:G to T:A, ...
Each base yields characteristic bands that can be used to identify the nucleotides. Because the SERS spectra of the unthiolated DNA strands contain features associated with all of the constituent bases, it should be possible to detect even single changes in the DNA sequences. Such an analysis ...
DNA is found in all cells asbase pairsmade of four differentnucleotides. Each base pair is formed from two complementary nucleotides bonded together. The four bases in DNA's alphabet are: Adenine Cytosine Guanine Thymine Adenine and thymine always bond together as a pair, and cytosine and guanin...
You gaze around the room, searching for someone to call on. But no students meet your eyes, and most hunker down in their chairs to get out of sight. Most of us know the existential dread of being called on in class when we’re not sure what to say, but little do we know the ...
1. What do we know about the robot? A.It can recognize and respond to human emotions. B.It can develop new machines for children. C.Its color can be changed easily. D.Its material is very common.2. Who was one of the designers of the robot? A.Albert Einstein. B.Dr. Hanson. C...
DNA is made up of four different nucleotide bases; adenine, thymine, guanine, and cytosine. The four nucleotide bases pair up in a specific manner to form DNA. Adenine and thymine are one pair and are bonded with two hydrogen bonds. Guanine and cytosine are the second pair and are bonded...
