a gene mutation can be acquired throughout life or it is genetic ex sickle cell anemia
chromsome mutations have more pronounced effects and are due to a change in the number of chromosomes or a change in the structural effect that are inherited.. ex downs syndrom

∙ 11y agoA Chromosome mutation is a mutation where you may get an extra chromosome and that chromosome may be mutated, a point mutation is at one point in a chromosome such as a curtain letter (A,C,T,G)

So basically it's the difference between a variation in a sequence of DNA that could cause a trait or disease versus DNA mutations can just be sequencing errors but chromosomes can have doubling errors in which correct sequenced DNA is accidentally doubled or tripled or left out

What can cause changes in DNA sequences?
mutations
Circular extra genomic DNA is called?
A circular band of DNA that exists separate of chromosomal DNA is called a plasmid. Plasmids reside within bacteria cells and can replicate independently of the chromosomal DNA.
Why are only neutral mutations useful for molecular clocks?
Only neutral mutations are useful for molecular clocks because they accumulate in the DNA of different species at the same rate, while other mutations do not.
How does polymerase prevent mutations?
It checks DNA for errors during replication.
The chromosomal DNA is duplicated in what?
I think the nucleus is the best answer.
Why is your DNA like no one else's?
Mutations and chromosomal crossover.
Name two major types of mutations What do they have in common How are they different Give an example of each?
Gene and chromosomal; both change DNA sequence that affects genetic information. Gene mutations involve a change in one ore several nucleotides in a single gene, whereas chromosomal mutations involve changes in the number or structure of whole chromosomes
What is extrachromosomal replicon?
+other than chromosomal DNA is known as extra chromosomal DNA like plasmids, mitochondria and chloroplast containing DNA.
What is the relative amounts of DNA in parent and daughter cells in mitosis?
The relative amounts of DNA in mother and daughter cells in mitosis are identical, as long as no chromosomal mutations occurred.
Changes in a DNA sequence that affect an entire chromosome or multiple chromosomes?
The DNA sequence of an entire chromosome is affected by a nitrogen base. A mutation is any mistake or change in the DNA sequence.
What is the difference between gene and chromosomal mutation?
A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome. A chromosomal mutation is a mutation involving a long segment of DNA, it is a any change in the structure or arrangement of the chromosomes. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.It is also referred to as a chromosomal rearrangement The differences between Gene mutation and Chromosome mutation are ; 1- Chromosome mutations involve changes in the structure of a chromosome OR the loss or gain of a chromosome while Gene mutations involve a change in the nucleotide -base sequence of a gene on a DNA molecule. 2- Chromosomal mutations are changes in the structure or the numbers of chromosomes (a gain or loss). Gene mutations involve changes in the nucleotide sequence of the DNA molecule. 3-A gene mutation is a permanent change in the DNA sequence that makes up a gene. Mutations range in size from a single DNA building block (DNA base) to a large segment of a chromosome while a chromosomal mutation is a mutation involving a long segment of DNA, it is a any change in the structure or arrangement of the chromosomes. These mutations can involve deletions, insertions, or inversions of sections of DNA. In some cases, deleted sections may attach to other chromosomes, disrupting both the chromosomes that loses the DNA and the one that gains it.It is also referred to as a chromosomal rearrangement 4-gene mutation is just a substitute in any old random nucleotide for any old random nucleotide chromosome mutation is missing of chromosome or +1 chromosome (down's syndrome).
What causes a baby to come out deformed?
Mutations in their chromosomal DNA. Each parent gives chromosomes to the baby, and when they meet sometimes there are doubles of chromosomes, missing chromosomes, or mutated chromosomes which cause abnormalities in the DNA and overall the child.
What are plasmid genes?
A plasmid is an extra chromosomal DNA molecule separate from the chromosomal DNA which is capable of replicating independently from the chromosomal DNA http://en.wikipedia.org/wiki/Plasmid I think this is far use.
Can mutations in human gives special abilities?
I don't think so. Mutations are changes in the genetic material of a cell, and the cause of a mutation in most cases are either point mutations (only a single base pair in a DNA is involved) or chromosomal mutations (involve rearrangements in big regions of chromosomes). But changing rearrangements does not exactly change what is in the DNA itself, and small changes could not give special abilities since we know you need a lot of changes to become Spiderman In most cases, mutations tent to be harmful (causing cancer) rather than be helpful.
What can cause changes in DNA sequences?
mutations
What is the difference between plasmid and episomes?
Plasmid DNA is an extra-chromosomal DNA molecule, it cannot link up with chromosomal DNA, and it contains the genetic informations that are necessary for its own replication. Episomes is any kind of extra-chromosomal DNA that can link up with chromosomal DNA. That is the main difference between them two. Episomes are usually larger than other extra-chromosomal DNA. An example of episome are the viruses, because they intergrate their genetic material into the host's chromosomal DNA.The only difference between the plasmid and the episome is the integration i-e plasmid can not integrate while episome can integrate into the genome.
The chromosomal DNA is duplicated in?
nucleus
