What broken part of a chromosome becomes attached to a nonhomologous chromosome with no molecular loss?
A broken part of a chromosome that becomes attached to a nonhomologous chromosome without molecular loss is known as a translocation. This can lead to genetic disorders if the translocated segment disrupts the function of important genes located on the chromosome.
A chromosome that has been broken and rejoined in a reversal sequence has undergone?
A chromosome that has been broken and rejoined in a reversal sequence has undergone an inversion mutation. This can lead to changes in gene expression and potentially affect the phenotype of an organism.
In which phase are the spindle broken down the chromosome uncoil and the cytoplasm divides to yield two new diploid cells?
telophase telophase
How does acute lymphoblastic leukemia arise?
Acute Lymphoblastic Leukemia arises due to attachment of a broken part of one chromosome to another.
The Y chromosome is larger and carries fewer genes than the X chromosome?
No. The Y chromosome is much smaller than the X chromosome. There are only about 70 active genes on the Y chromosome and many more deleteriously mutated one. The X chromosome contains many more active genes and only crosses over marginally with the Y chromosome.
Is an x chromosome and chromosome the same thing?
An x chromosome is specifically a feminine chromosome. With a x and y chromosome its male, with a x and x, it is a female.
Which chromosome contains the sex gene?
chromosome 1 chromosome 1
What are the name of 23 chromosomes in human body?
No, there are 46 chromosomes in one cell. A gamete, or sex cell, has 23 chromosomes because during fertilization, the female and male gametes (egg and sperm, respectively) come together to form a new cell with 46 chromosomes
What is the designation for the short arm of a chromosome?
Chromosome # + pso the short arm of Chromosome 11 is referred to as 11p
Does an x chromosome looks the same as a y chromosome?
No. An 'X' chromosome looks like an 'X'. The 'Y' chromosome looks like a deformed 'X'. It is noticeably different to an 'X' chromosome. Also, the 'Y' chromosome is only a third of the size of an 'X' chromosome - an 'X' chromosome is 155 million base pares, while the 'Y' chromosome is only 58 million base pairs.
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 the difference between Edward's syndrome and Patau's syndrome?
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
