Which of the following amino acid residues are often involved in proton transfers in enzyme-catalyzed reactions? a. histidine, aspartate, lysine, and serine b. histidine, aspartate, glutamate, arginine, and lysine c. glutamine, asparagine, lysine, and...
Answer and Explanation: The nine essential amino acids are: histidine isoleucine leucine lysine methionine phenylalanine threonine tryptophan valine These amino acids are...
Anticodons are the regions on the tRNA molecules that are complementary to the codons on mRNA. A codon on the mRNA will be recognized by the appropriate anticodon, bringing the appropriate amino acid into the ribosome to be added to the growing protein chain...
What is the minimum number of single-nucleotide substitutions that would be necessary for the amino acid replacement Tyr {eq}\to {/eq} Gly? Codons: Codon is the term used in the central dogma of biology that refers to the 3 nucleotide...
1. What is the mRNA sequence for the following segment of DNA: --AAACCAAGAGGCTCT--? 2. Based upon the mRNA sequence, what is the peptide? What amino acids do the following ribonucleotide codons code for? (a) AAU (b) GAG (c) UCC (d) CAU (e) A...
What would be the complementary sequence? (2) How many codons are in this sequence? a. What is the mRNA sequence for the following segment of DNA: --AAACCAAGAGGCTCT--? b. Based upon the mRNA sequence, what is the peptide sequence? a. What is the...
If the base sequence along a segment of DNA were TCGTA, what would be the antisense oligonucleotide synthesis from this sequence? (1) Consider the DNA sequence ACGATTGCC. What would be the complementary sequence? (2) How many codons are in this seq...
