Where are alleles located?
Alleles are located on chromosomes, which are found in the nucleus of a cell. They can exist in pairs on homologous chromosomes, with one allele from each parent. Alleles are the different forms of a gene that can code for different traits or characteristics.
An allele is either what two things?
Alleles are different forms of a gene found on chromosomes on sites called loci
What is the name given to a pair of chromosomes that have matching locations for alternate forms of the same gene?
homologous chromosomes
How do you write the definition of homologous chromosome using the terms gene and allele?
Homologous chromosomes are pairs of chromosomes in a diploid organism that share the same genes at the same loci. Each gene may have different forms, called alleles, on the homologous chromosomes.
What has chromosomes?
Any living thing has chromosomes; different species have different amounts!
What is the condensed form of DNA referred as?
The highly condensed forms of DNA (and proteins) are known as chromosomes.
What happens to the chromosomes at the end of propahse 1 that is different fomr mitosis?
prophase produces mitosis and forms more cells to make even more cells!
What do you call DNA in the nucleus before it condenses to form chromosomes?
DNA forms nucleosomes (beads on the string) by combining histone proteins, nucleosomes condense into chromatins before it forms Chromosomes
Process during which chromosomes appear?
Chromosomes replicate during cell division, so are present as a new cell forms.
How is the chromosomes in the eukaryotes different from the structer of chromosomes in prokaryotes?
in eukaryotic chromosomes it produces DNA to live and in prokaryotic chromosomes it is nothing but bacteria.
Do Different Eukaryote organisms have different amount of Chromosomes?
Yes, different eukaryotic organisms can have different numbers of chromosomes. For example, humans have 46 chromosomes, while corn plants have 20 chromosomes. The number of chromosomes can vary widely among eukaryotic species.
How may chromosomes does sperm cells have?
Well, every species is different as different species have different numbers of chromosomes. So it would depend on the organism. But, if you are asking about humans. Humans have 46 chromosomes. So a human sperm would have 23 chromosomes.
