Describe four types of mutation resulting from the breakage of chromosome?
Deletion: a segment of the chromosome is lost during breakage. Duplication: a segment of the chromosome is copied and inserted back into the chromosome following breakage. Inversion: a segment of the chromosome is reversed and re-inserted following breakage. Translocation: a segment of the chromosome breaks off and joins a different chromosome.
A segment of DNA on a chromosome that codes for a specific trait?
A gene is a segment of DNA that contains the instructions for making a specific protein or RNA molecule, which determines a particular trait or characteristic. Each gene is located at a specific position on a chromosome in the cell's nucleus.
What is partial tandem duplication?
The extra chromosome segment may be located immediately after the normal segment in precisely the same orientation forms the tandemWhen the gene sequence in the extra segment of a tandem in the reverse order i.e, inverted , it is known asreverse tandem duplicationIn some cases, the extra segment may be located in the same chromosome but away from the normal segment - termed as displaced duplicationThe additional chromosome segment is located in a non-homologous chromosome is translocation duplication.
What is a loss of complete chromosome called?
deletion-occurs when an end of a chromosome breaks off or when two simultaneous breaks lead to the loss of an internal segment
What is a segment with information to make a protein?
A segment of DNA on a chromosome that controls the production of a protein is called a gene. Chromosome a cellular structure that contains DNA.
What is it called when a segment of a chromosome is repeated?
The mutation in which a segment of a chromosome is repeated is known as duplication.

A segment of DNA on a chromosome that codes for a specific trait?
A gene is a segment of DNA that contains the instructions for making a specific protein or RNA molecule, which determines a particular trait or characteristic. Each gene is located at a specific position on a chromosome in the cell's nucleus.
4 chromosome mutations?
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
What is partial tandem duplication?
The extra chromosome segment may be located immediately after the normal segment in precisely the same orientation forms the tandemWhen the gene sequence in the extra segment of a tandem in the reverse order i.e, inverted , it is known asreverse tandem duplicationIn some cases, the extra segment may be located in the same chromosome but away from the normal segment - termed as displaced duplicationThe additional chromosome segment is located in a non-homologous chromosome is translocation duplication.
What is biological term for segment of a chromosome that controls each characteristic?
Genes
What is a loss of complete chromosome called?
deletion-occurs when an end of a chromosome breaks off or when two simultaneous breaks lead to the loss of an internal segment
What is the shorter segment of a chromosome?
Just a DNA strand
What are the four types of chromosomal mutations?
There are four different types of chromosomal mutations: Deletions, Translocations, Duplications and Inversions
What is an mutation?
An Inversion mutation is a mutation that causes a reversal in the order of a segment of a chromosome within the chromosome, or a gene.
If a segment of a chromosome breaks away and joins to a non-homologous chromosomes what is it called?
When a segment of a chromosome breaks away and joins a non-homologous chromosome, it is called a translocation. This can lead to gene disruptions and potentially cause genetic disorders.
A segment of DNA found on a chromosome that codes for a protein?
a gene
