First of all a gene by definition codes for something so there is no such thing as a "non coding gene". To your question non-coding DNA is no more prone to mutation. A mutation in a non-coding region is far more likely to passed onto offspring because a mutation has no effect on the organism that gets it. A mutation in a gene is more likely to be bad thing than beneficial. So over time (many generations) there are more differences in non coding regions of DNA between individuals. This why DNA fingerprinting looks at differences in non coding regions between people to find unique profiles.
What else can I help you with?
Which types of mutation affects more genes a gene mutation or a chromosomal?
a gene is passed on from generations and a chromosome is just found in certain cells
Is it better to make copies of genes or non-coding segments for genetic research and experimentation?
When it comes to genetic research and experimentation, it is generally more beneficial to make copies of genes rather than non-coding segments. Genes contain the instructions for making proteins, which play a crucial role in determining an organism's traits and functions. Non-coding segments, on the other hand, do not code for proteins and their functions are not as well understood. Therefore, focusing on genes can provide more valuable insights and advancements in genetic research.
What are introns and pseudogenes Are they the same?
Introns and pseudogenes are not the same.An intron is a segment of DNA that "intrudes" into or "interrupts" a coding stretch of DNA. Many genes in humans have introns, but bacteria seem to have none. To take an extreme example, the human dystrophin gene has 79 exons (separate coding segments) spread over more than 2.3 million base pairs.A pseudogene is a DNA segment that resembles a functional (coding) gene, but does not itself code for a gene product. It seems likely that pseudogenes arise when a gene is copied within the genome, and one of the copies drifts away from the functional sequence. "Pseudogene" literally means "false gene".
In eukaryotes the noncoding portions of DNA are called what?
You get the entire organism from the single fertilized cell. There should be no doubt that this process is conducted by your genes only. So all the cells of your body are made in very particular order by your genes only. After the individual is formed, the functions of the most of the genes is over. You can easily check the function of the particular gene by sacking the same in zygote. The very important genes, which are involved in primary steps, will create the serious disorders in that particular animal. In such case the animal may not even survive. He may not have some important organ or system like liver or cardiovascular system or respiratory system. Step by step the function of the gene becomes less and less important, but then that is enough to cause some disorder like mucoviscidosis or poly-cystic kidney disease, in the patient, with slight variation. There are more than enough permutations and combinations, to produce all types of cells in the body of all the organisms on the earth, past, present and future. That is why 98 % genes in humans are noncoding. Some people call these sections "junk DNA" but more research has shown that they can play a significant role in controlling cell development.
Why do forensic labs analyze non-coding DNA and not genes?
Coding DNA or exons are varying among individuals. But non-coding DNA doesn't vary among individuals and they don't carry information about gene expression patterns. Therefore, non-coding DNA is used in forensic analyses.
Which types of mutation affects more genes a gene mutation or a chromosomal?
a gene is passed on from generations and a chromosome is just found in certain cells
Why are noncoding regions of DNA more discriminating than coding region?
Noncoding regions of DNA are often more discriminating than coding regions because they play critical roles in regulating gene expression, chromatin structure, and genome stability. These regions are involved in processes such as transcription factor binding and the formation of RNA molecules that can influence gene activity. As a result, mutations in noncoding regions can have significant functional impacts, making them subject to stronger evolutionary pressures. In contrast, coding regions primarily determine protein sequences, which are somewhat more tolerant to variation due to the redundancy in the genetic code.
Describe what genes are and explain what makes a disease genetic?
genes are what make up your DNA. each gene has two alleles, and whether those alleles are dominant or recessive determines what trait you get. Every trait has at least on gene coding for it, and some have more. a disease is genetic when there is a gene coding for it, as opposed to just a mutation or something environmental causing it.
Would a point mutation or a frame shift mutation more likely produce a neutral mutation?
A point shift mutation is more likely to produce a neutral reaction. This is because it involves a change in one nucleotide. A frame shift mutation is more deleterious because it involves the insertion or deletion of multiple base pairs within a gene's coding sequence.

Do chromosomes have the same or different genes?
There are many more genes than chromosomes. The Human Genome Project currently has identified about 20,000 protein-coding genes, while there are only 46 chromosomes in the human genome.
Do exons contain noncoding DNA?
Exons are the portions of a gene that code for the final protein product and typically do not contain noncoding DNA. Noncoding DNA is more commonly found in introns, which are the intervening sequences between exons.
What is the type of mutation that causes color blindness?
Color blindness is primarily caused by mutations in the genes responsible for producing photopigments in the cones of the retina, particularly the genes for red and green photopigments located on the X chromosome. The most common type of mutation is a point mutation, which can lead to the absence or alteration of these photopigments, affecting the ability to perceive certain colors. Since these genes are located on the X chromosome, color blindness is more prevalent in males, who have only one X chromosome.

Do humans have fewer or more proteins in their body than protein coding regions?
Number of proteins produced is of course more than the number of coding regions/genes/mRNAs. This is because of biological processes like alternate splicing and other post translational changes.

Mutations in introns are less likely to affect phenotype then mutation in exons?
Mutations in introns are less likely to affect phenotype because introns are not translated into protein, unlike exons which contain coding regions for proteins. Introns are involved in regulation of gene expression through processes such as alternative splicing, but mutations within introns typically have a more subtle impact on gene expression compared to mutations in coding regions (exons).
