What else can I help you with?
What amino acid would be made form the mRNA code for a a a?
AGT codes for the amino acid serine and CTT codes for the amino acid leucine.
What codon code is for amino acid (Lys)?
The amino acid lysine (Lys) is encoded by three codons: AAA and AAG. These codons are found in the messenger RNA (mRNA) and are recognized by transfer RNA (tRNA) during protein synthesis.
For which amino acid is the one letter code q?
glutamine This is the side chain amidated form of Glutamate, so it is quite polar but carries no formal electrical charge when present in a polypeptide. You can find a good introductory description of the amino acids, their structures and classification, at this web site www.bio.davidson.edu/Biology/aatable.html
What anti codon bonds with the RNa codon CCa?
The tRNA anticodon is GGU, which codes for the amino acid proline (pro).
Why is the mRNA code for amino acids said to be redundant?
The code for creating amino acids is said to be redundant because some codons code for the same amino acid (i.e. there is redundancy because several codons have the same function). For example, the RNA codons AAA and AAG both code for the amino acid Lysine. The codons ACU, ACC, ACA and ACG all code for Threonine.
What is the amino acid sequence that is coded for the mRNA sequence AUG-ACG-AAA-AGA-AGG-GGA-GCC-GCU-UCC-UAA?
The amino acid sequence is: UUU-UCU-UCC-CCU-CGG-CGA-AGG-AUU.

What does it mean to say that the genetic code is triplet?
Prior to understanding the details of transcription and translation, geneticists predicted that DNA could encode amino acids only if a code of at least three nucleotides was used. The logic is that the nucleotide code must be able to specify the placement of 20 amino acids. Since there are only four nucleotides, a code of single nucleotides would only represent four amino acids, such that A, C, G and U could be translated to encode amino acids. A doublet code could code for 16 amino acids (4 x 4). A triplet code could make a genetic code for 64 different combinations (4 X 4 X 4) genetic code and provide plenty of information in the DNA molecule to specify the placement of all 20 amino acids. When experiments were performed to crack the genetic code it was found to be a code that was triplet. These three letter codes of nucleotides (AUG, AAA, etc.) are called codons. The genetic code only needed to be cracked once because it is universal (with some rare exceptions). That means all organisms use the same codons to specify the placement of each of the 20 amino acids in protein formation. A codon table can therefore be constructed and any coding region of nucleotides read to determine the amino acid sequence of the protein encoded. A look at the genetic code in the codon table below reveals that the code is redundant meaning many of the amino acids can be coded by four or six possible codons. The amino acid sequence of proteins from all types of organisms is usually determined by sequencing the gene that encodes the protein and then reading the genetic code from the DNA sequence.

How is it that a code consisting of only 4 letters as in DNA can specify all the different parts of an organism and account for all the diversity of organisms on this planet?
VERY simplified, genes can be looked at as strings of codons. Each codon is a section of 3 base pairs which code for an amino acid. When the genetic material is processed it takes the amino acids and strings them together into proteins of many combinations and lengths which perform all the different tasks.
Why does a base substitution mutation in a gene not always result in a different protein?
A base substitution mutation in a gene may not always result in a different protein because of redundancy in the genetic code. Some amino acids are encoded by multiple codons, so a mutation may still code for the same amino acid. Additionally, mutations in non-coding regions or silent mutations that do not change the amino acid sequence may not alter the protein product.
A peptide has the sequence nh2-phe-pro-lys-gly-phe-pro-cooh what sequenes in the coding strand of the DNA codes for this peptide?
The sequence in the coding strand of the DNA that codes for this peptide is 5'-TTC-CCT-AAG-GGC-TTC-CCT-3'. DNA sequences are read in groups of three nucleotides (codons). Each codon corresponds to a specific amino acid in the peptide sequence.
What anticodon matches the codon cuc?
The anticodon sequence would be GAG-UUC-ACG-AAG.
Why are there 20 amino acids in a protein?
There are 64 DNA codons (possible sequences of the 3-letter nucleotide bases A - adenine, T - thymine, which is replaced by U - uracil in RNA, C - cytosine and G - guanine) but only 20 possible amino acids because of the possibility of mutations that would replace one nucleotide base with another. For example, both AAA and AAG code for the production of lysine. This means that if a codon sequence was originally AAA and a mutation or an error in copying the DNA strand placed guanine in place of the final adenine, lysine would still be coded for. Though there are many possible errors that would cause an incorrect amino acid to be produced - for example, if cytosine was in place of the final adenine, asparagine would be coded for - having more than one codon per amino acid reduces the chances of a wrong amino acid being produced.
