What is the No of chromosome in a diploid yeast cell?

Haploid S. cerevisiae have 16 nuclear chromosomes; thus diploid have 32.

Haploid S. pombe have 3 nuclear chromosomes; thus diploid have 6.

(etc. etc. etc. depending upon what "yeast" you are referring to)

How do proteins help condense chromosomes?

Proteins like histones help condense chromosomes by wrapping DNA around them to form nucleosomes. This compacts the DNA into a more condensed structure, making it easier to fit inside the cell's nucleus and regulate gene expression.

What are changes in chromosome structure called?

Changes in chromosome structure are referred to as chromosomal abnormalities. These abnormalities can include deletions, duplications, inversions, and translocations, which can lead to genetic disorders or other health conditions.

What is an example of chromosome?

Well, you only have two choices or examples: X and Y.

What is a chromosome unit?

A chromosome unit refers to a single chromosome, which is a long strand of DNA containing genetic information. In humans, a chromosome unit consists of two sister chromatids joined together at a centromere. Chromosomes are located within the nucleus of cells and play a crucial role in storing and transmitting genetic information during cell division.

How can you detect cystic fibrosis?

Cystic fibrosis can be detected through a combination of genetic testing, sweat chloride testing, and certain diagnostic imaging tests like chest X-rays or CT scans. Additionally, symptoms such as chronic respiratory issues, digestive problems, and salty skin can also be indicators of cystic fibrosis. A thorough medical evaluation by a healthcare provider is necessary for an accurate diagnosis.

Is DNA organized on chromosomes?

Yes, DNA is organized into structures called chromosomes in most cells. Chromosomes are made up of DNA and proteins, and they contain the genetic information that is passed from one generation to the next. Each species has a specific number of chromosomes that are located in the cell's nucleus.

What molecule is a chromosome made of?

A chromosome is made of DNA, which consists of long chains of nucleotides. These nucleotides are composed of a phosphate group, a sugar molecule, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine).

Is a chromosomes a DNA molecule?

Yes, chromosomes are made of DNA and protein molecules called histones. Edit from another user: False, they're made of material called chromatin. Edit from user #3: Chromosomes and chromatin are actually the same thing, except in different form. Both chromosomes and chromatin are made up of a strand of DNA wrapped around histone protein, except chromatin is in a long and stringy form while chromosomes are a compacted and twisted version of chromatin.

The y chromosome closely resembles many of the other chromosomes. What did you have to do to determine that it was the y chromosome?

Scientists identified the Y chromosome through karyotyping, a technique that stains and pairs chromosomes based on length, centromere position, and banding patterns. When studying a male individual's chromosomes, researchers observed that one pair was noticeably different from the others, identifying it as the Y chromosome due to its distinct characteristics and role in determining male sex.

What is the complicated process of chromosome separation?

Chromosome separation, or mitosis, is a highly orchestrated process that involves multiple steps. First, the chromosomes condense and align at the center of the cell. Then, they are pulled apart by spindle fibers attached to the centromere of each chromosome. Finally, the cell divides into two daughter cells, each with a complete set of chromosomes. Any errors in this process can lead to genetic abnormalities or cell death.

What do chromosomes and meiosis have to do with each other?

Chromosomes carry genetic information, which is passed on during the cell division process of meiosis. Meiosis involves two rounds of cell division that result in the formation of gametes (sperm and egg cells) with half the number of chromosomes as the parent cell, allowing for genetic diversity through the random assortment of chromosomes.

One half of a duplicated chromosome?

A duplicated chromosome consists of two identical sister chromatids joined at the centromere. Therefore, one half of a duplicated chromosome refers to one of these sister chromatids, which contains a copy of the genetic material from the original chromosome.

What are genes chromosomes?

if a cat has 38 chromosomes in each of its body celss, how many chromosomes will be in each daughter cell after mitosis?

How do you make y chromosomes stronger?

There is no way to make Y chromosomes stronger as they are a natural part of genetic makeup. Y chromosomes determine male characteristics and are passed down from father to son. Engaging in a healthy lifestyle, proper nutrition, and regular exercise can help maintain overall genetic health including Y chromosomes.

How do you spell chromosomes?

That is the correct spelling of the plural noun "chromosomes" (genetic structures in cells).

The haploid chromosome number is created when?

The haploid chromosome number is created during the process of meiosis, which involves two divisions that ultimately result in the formation of haploid gametes (sex cells) with half the number of chromosomes found in the original cell.

How many chromosomes does a mouse's liver have?

A mouse's liver cells have the same number of chromosomes as other body cells, which is typically 40 chromosomes.

What process results in the formation of chromosome c from chromosomes a and b?

Chromosome c can form through a process called genetic recombination or crossing over during meiosis. This process involves the exchange of genetic material between chromosomes a and b, leading to the creation of a new chromosome that contains a combination of genes from both parent chromosomes.

Does chromosome have a membrane?

No, chromosomes aren't organelles, membrane-bound or otherwise.

How many chromosomes in allium cepa?

Allium cepa, also known as onion, has a total of 16 chromosomes. These chromosomes exist as eight pairs, with each pair consisting of two homologous chromosomes.

Who has y chromosomes?

In humans, males have one Y chromosome and one x chromosome in addition to 44 other chromosomes, females have two Xs. Because of errors in gamete (egg or sperm) production, some humans have XYY, XXY, or some other combination of sex chromosomes.

What cell has the least chromosomes?

In humans, gametes (Ove and Sperm cells) have the least number of chromosomes

How many chromosomes do hermaphrodites have?

Hermaphrodites can have a variety of chromosome combinations, depending on the species. In humans, individuals with both male and female reproductive organs (a type of intersex condition) typically have the usual chromosome pair of 46, but may have variations such as XXY or XYY. In other species, such as earthworms or snails, hermaphrodites may have different numbers of chromosomes.

How many sperm chromosome do cats have?

Cats, like most mammals, have 38 chromosomes in total. However, when it comes to sperm cells, they only carry 19 chromosomes, half of the total number, which is due to the process of genetic recombination during meiosis.
