There is a reason why random mistakes occur. The genes themselves carry a code for mutation which is expressed randomly without generational continuity. It may be considered recessive in the extreme. The ability for random mutation to "test out" new designs is at the very core of Darwinian evolution. These mistakes are supposed to happen. If they did not happen we would not be sharing this very info with each other as we would not exist.

What are known as gene mutations and occur at a single point in the DNA sequence?
Mutations that occur at a single point in the DNA sequence are Point Mutations.
Discuss the causes of variation Living organisms?
Causes of variation is random mutation. Random mutations constantly occur in the genomes of organisms; these mutations create genetic variation. If all living things were same, we will all use up one type of food as our nutrient source and eventually we will run out of food to consume.. making less likely for us to survive..
Is substitution mutations or insertion mutations worse?
Insertions generally are more harmful. An insertion causes a "frameshift" to occur, thus changing the entire amino acid sequence of the entire strand. Substitutions only change one base, which can sometimes not mess up the amino acid sequence at all.
What is one way that changes occur in a DNA Sequence?
Mutations (point mutations, inversions, translocations...) cause changes in DNA Simply stated, a mistake made while DNA copies causes changes in DNA.
What are mistakes that can happen during the coping of DNA?
Some common mistakes that can occur during the copying of DNA are: Insertion or deletion of bases: Errors in DNA replication can lead to the insertion or deletion of nucleotides, resulting in a frameshift mutation. This can alter the reading frame and disrupt the protein-coding sequence. Substitution of bases: Substituting or swapping one base for another can result in a point mutation. This can lead to changes in the amino acid sequence during protein synthesis, affecting protein function. Replication errors: DNA polymerase enzymes can make mistakes by incorporating incorrect nucleotides during replication, resulting in mismatched base pairs. Proofreading mechanisms usually help to correct these errors, but some mistakes can still get through, leading to mutations.
Sometimes random mistakes occur in a DNA sequence. These mistakes are referred to as .?

What is a random sequence limit?
To the best of my knowledge, a random sequence limit imposes restrictions on random number generation. For example, one may want to generate random numbers such that any number does not occur consecutively three times. Another definition of a random sequence limit is the number that a sequence of random measurements of some property converge to as the number of measurements increase.
Are mutations predictable?
No, they are random, This means that they occur in no set numerical order. So, though they can not be predicted it is certain, with the mistakes made in replication and other factors, that they will occur.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
How do mutations occur in an organism?
In the base sequence of the DNA part of the DNA changes which causes a change in the whole DNA which is called a mutation.
The order in which the actions occur is known as sequence of what?
Sequence of Events.
What do you call events that occur in a sequence?
You call them 'sequence of events'.
How and why variation occur in rate and sequence of development and learning?
how and why variation occur in the rate and sequence ot develpment and learning
What can occur as a result of a change in the sequence of nucleotides in a strand of DNA?
The addition or deletion of a nucleotide can lead to a Frameshift mutation. The Frameshift mutation causes a "shift" in the reading frame of the codons in the mRNA. This may lead to the change in the amino acid sequence at protein translation.
What do scientists mean by mutations are random?
Mutations are changes in the nucleotide sequence of an organism's SNA, ultimately creating genetic diversity.They can be caused by mutagens--chemical or physical agents that interacts with DNA and causes mutations.They can also occur simply by error in DNA copying during cell reproduction.These situations are random, as in they are not planned and can happen to any DNA strand at any time.
Hind iii recognizes a sequence of 6 nucleotides aagctt as a cut site what are the odds that this sequence will occur in a random chain of DNA?
1 out of 4,096 (4 x 4 x 4 x 4 x 4 x 4)
Why are giants not on the main sequence?
Because, giants can only occur once they leave the main sequence.
