What else can I help you with?
What results if a fragment of a chromosome breaks off and then reattaches to the original chromosome at the same place but in the reverse direction?
This is a type of chromosomal rearrangement called an inversion. Inversions do not typically result in the loss or gain of genetic material, but can affect gene expression by disrupting the normal order and orientation of genes. Inversions can be inherited or arise spontaneously during cell division.
What is it called when a fragment of a chromosome breaks off and then reattaches to the original chromosome at the same place but in the reverse direction?
This process is called an inversion mutation. It involves a fragment of a chromosome breaking off, flipping, and rejoining at the same location but in the reverse orientation. Inversions can have different effects on gene expression and can sometimes lead to genetic disorders.
What is the DNA chromosome called that breaks off and reattaches to a homologous chromosome that is paired up in meiosis?
This is a type of mutation called translocation.
Why electric field breaks the space-inversion symmetry while magnetic field breaks the time-reversal symmetry?
Electric field breaks space-inversion symmetry because it changes the sign of charges under spatial inversion. Magnetic field breaks time-reversal symmetry because reversing the direction of time changes the direction of the field's rotation or flux lines.
What is it called when one chromosome breaks off and is added to a different chromosome?
translocation i'm doing the same worksheet for my finals study guide, and in my book it discussed this.
