How arrangement of codons in the genetic code minimize the impact of mutations?

Based on the DNA or RNA, based on the organism and based on the process of RNA and DNA the arrangement of codons will occur.
During translation process in mRNA the tRNA's anticodon region comes and binds to the start codon ( AUG, GUG, UUG) of the mRNA where the translation process initiated and the process was and at the stop codon ( UAG, UAA, UGA) region the translation process was terminated. From organism to organism the arrangement of the codons will changed based on the number of basepairs.

What is a genetic wheel?
Because of four different bases, there are 64 possible three-base codons (4x4x4=64). the genetic wheel shows all 64 possible codons of the genetic code.
All organisms have a genetic code made of?
All organisms have a genetic code made of these three nucleotide sequences called codons.
What is the genetic code read in?
Three-base triplets called codons. Each codon will be translated into an amino acid during the process of translation.
The genetic code is universal but what does this mean?
this means that the same genetic code that is used in humans is used in all other types of organisms as well. anything from animals to plants to bacteria uses the same system of triplet nucleotide bases (codons) to code for a single amino acid when building a polypeptide. remember that the genetic code is also degenerate- each codon only codes for one amino acid, but there can be several different codons that call for the same amino acid.
How is genetic code made of?
Codons are three nucleotides in length. These nucleotides correspond with a specific amino acid or stop signal during protein synthesis.
What do point mutations and frame shift mutations have in common?
go look in your text book u have one u lazy ;) ;p

How many mutations are there in DNA?
Idealy, you would have possibly thousands of gene mutations. Gene mutations the word itself is very vague because it only describes one of the off spring genes being different then the parental one. Blue eyes are genetic mutations because the gene of brown-eyes were mutated to form blue-eyes. Technically speaking every single cell in your body can have a genetic mutation and you will still be able to do normal human functions. If you are looking for gene disorders, it varies according to how many genetic diseases you have such as Sickle-Cell disease, Huntington's syndrome or Haemophilia
Does the genetic code consist of overlapping codons?
No these are non-overlapping.
What are Genetic instructions are written in 3-base 'words' called?
Codons
WHAT IS FUNCTION OF THE CODONS UAAUAGUGA?
UAA, UAG, UGA are the 3 stop codons in the genetic code. Stop codons don't code for an amino acid because they cannot be recognized by a tRNA.
Ultraviolet radiation can cause mutations in the DNA of skin cells that have been overexposed to the sun This mutated DNA has no effect on future offspring because?
Mutations may occur in the rna codons
How are alleles and mutations related?
A gene is made with four bases adenine, guanine, cytosine and thymine. when proteins are synthesized the DNA unzips and complementary bases are matched up A-T and G-C. A codon is 3 bases which translate to an amino acid e.g. glycine is guanine, guanine and cytosine.
All organisms have a genetic code made of?
All organisms have a genetic code made of these three nucleotide sequences called codons.
Two causes of mutation?
Two types of mutations are Point Mutations and the other is Frameshift Mutations. Piont mutations include; deletions, insertions, and substitutions. These mutations casue a slight change in the amino acid usually resulting in a change in one amino acid. The second type, frameshift mutations involve many changes and almost always results in many changes in the codons.
Do mutations always cause pheynotypic changes?
No, because of the redundancy in the genetic code (several base triplets or codons code for the same amino acid) a point mutation, for instance, (a change in one base) may have no effect on the amino acid sequence in the protein, and so no effect on the expressed phenotype.
What is an example of a genetic disorder that is caused by insertion of an extra codons in the X sex chromosome?
Fragile X Syndrome
