What Happens during movement of chromosome to a non homologous chromosomes?
chromosomal Translocation
How many chromosomes would be found in a male fruit fly regular body cell?
there is 4 pairs of chromosomes in each cell for a fly!
What genes are found in the y chromosome?
The Y chromosome contains more than 59 million blocks of DNA and represents almost 2% of the total DNA in cells within the body. The Y chromosome contains between 20,000 to 25,000 genes within the human genetic make-up.
How can you identify the difference of a female chromosome and a male chromosome?
What differentiates a male from a female based off the chromosomes that are present is that a male organism will have X and Y chromosomes whereas a female organism will have X and X chromosomes.
Mitosis results into two genetically identical daughter cells as the parent cell.
What are chromosomes that have similar genetic information called?
Chromosomes that are similar are called homologous chromosomes. Chromosomes that have similar paired genes are called homolegous chromosomes. These copies have the same loci. These loci provide points along each chromosome that enable a pair of chromosomes to align.
Are prokaryotic chromosomes linear or circular?
Yes and no. Where Eukaryotes (like people, plants, fungi and ect) have multiple linear chromosomes Bacteria have one circular chromosome.
Yes Bacteria have one chromosome
No Bacteria don't have chromosomes
What is the chromosome number of a chicken?
A chicken has 78 chromosomal pairs (77 somatic & 1 sex pair). Chromosomes carry the genes with DNA. Chromosomes come in pairs because one is contributed by the father and the other comes from the mother.
The number of chromosomes in the two new daughter cells is identical to that of the mother cell. During cell division, such as mitosis, the chromosomes are replicated and evenly divided, ensuring that each daughter cell receives the same chromosome number as the original mother cell. Thus, if the mother cell has a specific number of chromosomes, each daughter cell will also have that same number.
How many copies do you have of each chromosome?
There will be two copies of each chromosome in all somatic cells called homologous chromosome..In case of reproductive cells there will be only one set during gamete formation...
What is the role or proteins in a chromosome?
Chromatin is tightly coiled and wrapped around proteins called histones to form structures called chromosomes
What is random distribution of homologous chromosomes during meiosis called?
Segregation distortion, non-mendelian segregation.
What is the sequence of DNA on a chromosome called?
A small section that codes for one amino acid is called a codon. A section that codes for proteins is called a gene.
What is bigger than a chromosome?
A molecule. elements are a series of atoms that form an element and several elements form a molecule.
What is homologous chromosomes frequently exchange portions of their DNA called?
It's called crossing over, and it generally only happens between homologous chromosomes.
A male child will inherit what chromosome?
Most males have XY chromosomes while most females have XX chromosomes.
How do differ chromatids differ from homologous chromosomes?
Sister chromatids are identical while homologous chromosomes are merely similar.
They are different because they separate the cells and then they become babies but only the homologous chromosomes do.
How is the haploid chromosome number?
The haploid chromosome number is half the chromosome number of the body cells. For example, in humans, body cells have 46 chromosomes. In human haploid cells (sex cells), there are 23 chromosomes.
Each half is called a sister chromatid.
There is much more DNA in the X chromosome. The Y has genes for addition growth and most of the testosterone that the body makes. A person can live with only one X but here are no people without the X and only the Y.
