What is the minimum number of bases necessary to code for each amino acid? (1 point)
Answer :
three
Proteins are built from a basic set of 20 amino acids, but there are only four bases. Simple calculations show that a minimum of three bases is required to encode at least 20 amino acids. Genetic experiments showed that an amino acid is in fact encoded by a group of three bases, or codon.

What is the minimum number of nucleotides needed to code for 100 amino acids?
four nitrogen bases in sequence make up the DNA code for an amino acid. True or False?
A protein consists of 300 amino acids. How many bases will be necessary in the processed mRNA, to code for this protein? Assume introns have been extracted from the processed mRNA.
The genetic code is "redundant" because: Question 1 options: Each amino acid is specified by only a single codon Most amino acids are specified by multiple codons Codons are groups of four consecutive DNA bases Each codon can specify multiple amino acids Question 2 (1 point) A mutation in the DNA may not result in change in protein function because: Question 2 options: Many different amino acids share similar chemical properties, so can substitute for one another without altering function...

Modify the structures (if necessary) to show the predominant form of the amino acid tyrosine at each pH. Be sure to include the proper number of hydrogen atoms on heteroatoms and the correct formal charges on atoms. At pH 2.5 = At pH 12.0 =
What is the one-letter code for the amino acid that has a side chain that contains a secondary alcohol? T K A E G Correct answer is T What is the one-letter code for the amino acid that has a methyl group as its side chain? E A T G K Correct answer is A
What is isoelectric point? The amino acid glycine has two ionizable groups: 1) a carboxyl acid group with a pKa of 2.72 and 2) an amino group with a pKa of 9.60. Calculate the pI of glycine.
Which amino acid is not used for the synthesis of purine or pyrimidine bases? Select one: a. glycine b. glutamine c. aspartate d. asparagine
The genetic code is considered degenerate because most amino acids are encoded by at least two different codons. Some researchers have hypothesized that during evolution the genetic code has been optimized for its intended use in different organisms. Reseachers can study this by examining the relationship between the frequency with which an amino acid appears in all the proteins in an organism and the total number of codons for an amino acid. An optimized organism would use amino acids in...
