Which of the following options is correct? Amino acids are monomers of a. disaccharides. b. proteins. c. nucleotides. d. steroids. Which of the standard amino acids is not enantiomeric? Which of the following 2 amino acid...
State which compounds can act only as hydrogen-bond donors, which can act only as hydrogen-bond acceptors, and which can act as both hydrogen-bond donors and hydrogen-bond ac What types of covalent bonds are pres...
Deoxyribonucleic Acid (DNA). This is a double-stranded structure that has nucleotides and is bonded together by covalent bonds between the deoxyribose and the phosphatic groups. The DNA helps in the expression and in the encoding of information. Answer and Explanation: Become...
In order to ensure an efficient antisense effect in the plant cells the synthesized antisense RNA should exhibit a minimum length of 15 nucleotides, preferably of at least 100 nucleotides and most preferably of more than 500 nucleotides. Furthermore, the DNA sequence encoding the antisense RNA shou...
The points of fusion with the human C regions are indicated with arrows. The putative sites of cleavage of the signal peptide are indicated by open triangle. The numbers refer to the nucleotides in the original cDNA clones. In our copending application Ser. No. 353,632, now abandoned, (...
The two types of nucleic acids, DNA and RNA, make up the genetic material of a cell. The nucleic acid monomer is called a nucleotide, and contains a pentose sugar, a nitrogenous base and a phosphate group. Nucleotides bind via covalent bonds as the phosphate group of one joins with the ...
Upon GPCR catalyzed GDP-GTP exchange on a G protein signaling partner, GTP-bound Gα subunits are generated, which interact directly with nucleotidyl cyclases to control the intracellular concentration of cyclic nucleotides by stimulating or inhibiting their production. The phototransduction system in ...
Some DARPins inhibited exchange of N-methylanthraniloyl (MANT) derivatives of guanosine nucleotides and were designated as nucleotide exchange inhibitors, while others directly blocked the interaction between active, GTP-loaded Ras and Raf and were designated Ras/Raf inhibitors. The amino acid sequence...
The isolated cDNA of USE1 lacked 259 nucleotides at the 5′ end, designated USE1short. Hence, it was necessary to also test full-length USE1, which is extended N terminally5. The complete USE1 cDNA was therefore cloned into the prey vector and a yeast two-hybrid assay was carried out ...
What enzyme matches RNA nucleotides to complementary DNA nucleotides? What will be a strand of complementary RNA for the DNA strand ATGACGGATCA? Which of the following represents a nucleotide of RNA? Phosphate-Sugar-Adenine Phosphate-Sugar-Uracil Phosphate-Sugar-Thymine The first and second answers ...
