What is the DNA chromosome called that breaks off and reattaches to a homologous chromosome that is paired up in meiosis?

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?
an inversion
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?
an inversion.
In inversion a chromosomal fragment breaks free and reattaches itself?
c. in reverse order
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.
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 occurs when a segment breaks of chromosome breaks off and reattaches to another chromosome?
translocation
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?
an inversion.
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?
an inversion
If a segment of a chromosome breaks away and joins to a non-homologous chromosomes what is it called?
a translocation
What are mutations in which a piece of code breaks flips and reattaches backwards?
Inverstions
What is 3 P duplication syndrome?
3p is product,price and process or promotion 3p is product,price and process or promotion 3P duplication syndrome is caused by a the inheritance of a portion of genetic information on chromosome 3 from its homologous partner. During meiosis, a portion of chromosome 3 breaks off from one copy of the chromosome and is inserted into the genetic information on the other chromosome 3. This leads to double copies of certain genes being inherited by the individual.
During crossing-over what happens to portions of chromatids?
breaks off and attach to adjacent chromatids on the homologous chromosome
In inversion a chromosomal fragment breaks free and reattaches itself?
c. in reverse order
What do the four types of chromosomal mutations do?
The four types of chromosomal mutation are deletion, duplication, inversion and trasnlocation. Deletion is the loss of all or part of a chromosome. Duplication is where a segment of a chromosome is copied. Inversion is where a section of a chromosome is reversed. Translocation is the process in where a part of one chromosome breaks off and attaches to a non-homologous chromosome.
The chromosome abnormality that occuswhen part of one chromosome breaks off and is add to a different chromosome is?
Translocation
What occurs in each stage of meiosis?
=Meiosis is a nuclear division process that divides the parental chromosome number in half. Meiosis differ from mitosis, a nuclear division mechanism. Meiosis sorts chromosomes into parcels not one but twice. Meiosis occurs only in specialized reproductive cells. Meiosis consist of two divisions: Meiosis I and Meiosis II. In meiosis I, each duplicated chromosome aligns with its partner, homologue to homologue. after they are sorted and arranged this way, each homologous chromosome is pulled away from its partner. all homologues move apart from their partners and end up in two new nuclei. when the cytoplasm divides, there are two daughter cells with one of each type of chromosome. the chromosomes are still duplicated. Then, during Meiosis II, the 2 sister chromatids of each chromosome separate. they become individual, unduplicated chromosomes. there are now four parcels of chromosomes; each contains one unduplicated chromosome of each type. new nuclear envelopes begin to enclose them as 4 nuclei inside 2 cells.==Meiosis I: Prophase I, Metaphase I, AnaphaseI, Telophase I (Interphase: DNA is replicated prior to meiosis I)==Meiosis II: Prophase II, Metaphase II, Anaphase II, Telophase II (No interphase DNA is not replicated prior to meiosis II)=
What distinguishes prophase 1 of meiosis from prophase of mitosis?
In Prophase I of meiosis, a tetrad is formed between 2 homologous chromosomes and their replicates. Small pieces are exchanged between the chromosomes and the tetrad breaks up. Then things happen as usual. So really the only difference is that there's genetic recombination.
