When chromosome become visible at the beginning of cell division what does each chromosome consist of?
Each chromosome consists of two identical sister chromatids that are held together by a centromere. These sister chromatids contain the genetic information needed for the cell to function and are divided evenly between the two daughter cells during cell division.
What chromosomes typically make up the sex chromosomes in a human male, and how do they determine the individual's biological sex?
The sex chromosomes in a human male typically consist of one X chromosome and one Y chromosome. The presence of a Y chromosome determines the individual's biological sex as male, while the absence of a Y chromosome results in a female biological sex.
What are chromosomes that are of the same size and function and the centromere is at the same location yet are not homologous?
These are known as isochromosomes. They consist of two identical arms due to an abnormal chromosome division where the centromere is duplicated. Despite their similarity in size and centromere position, they lack the genetic diversity found in homologous chromosomes.
What 2 substances do chromosomes consist of?
DNA and idk the other one or are you looking for chromosomes are composed of two chromatids held together by a centromere
How many base pairs do real human chromosomes consist of?
Real human chromosomes consist of different number of base pairs. For example, chromosome 1 is the largest and contains about 249 million base pairs, while chromosome 21 is the smallest and contains about 48 million base pairs. In total, all 46 human chromosomes contain approximately 3.2 billion base pairs.
When chromosomes become visible at the beginning of cell division what dose each chromosome consist of?
sperm
When chromosomes become visible at the beginning of cell division what does each chromosomes consists of?
The consist of DNA and various HistonesIn eukaryotes,genetic information is passed on by chromosomes. Well before cell division, each chromosome is replicated(copied). When copying occurs, each chromosome consists of two identical ''sister''chromatids.
When chromosome become visible at the beginning of cell division what does each chromosome consist of?
Each chromosome consists of two identical sister chromatids that are held together by a centromere. These sister chromatids contain the genetic information needed for the cell to function and are divided evenly between the two daughter cells during cell division.
Mitosis is cell division in which the chromosome number is what?
Mitosis is cell division in which the chromosome number stays the same. Although at some points throughout the cell cycle, chromosomes may consist of two sister chromatids
Where is a chromosome located inside a cell?
The chromosomes are located inside the nucleus of a eukaryote.
How chromatin reticulum become chromosome?
During cell division, the chromatin reticulum condenses further into visible structures called chromosomes. This condensation allows for the organized distribution of genetic material to daughter cells. The chromosomes consist of DNA wrapped around protein scaffolds, which help to package and protect the genetic material during cell division.
What are the parts of a chromosomes?
Chromosomes consist of DNA tightly wound around histone proteins, forming a structure known as chromatin. The key parts of a chromosome include the centromere, which helps in chromosome segregation during cell division, and the telomeres, which protect the ends of the chromosome from degradation. Chromosomes also have specific regions called genes that contain instructions for making proteins and controlling various cellular functions.
What chromosomes typically make up the sex chromosomes in a human male, and how do they determine the individual's biological sex?
The sex chromosomes in a human male typically consist of one X chromosome and one Y chromosome. The presence of a Y chromosome determines the individual's biological sex as male, while the absence of a Y chromosome results in a female biological sex.
What is organized in to 23 pairs?
Chromosomes are organized into 23 pairs in the nucleus of human cells. These pairs consist of one chromosome inherited from each parent, resulting in a total of 46 chromosomes.
What are chromosomes that are of the same size and function and the centromere is at the same location yet are not homologous?
These are known as isochromosomes. They consist of two identical arms due to an abnormal chromosome division where the centromere is duplicated. Despite their similarity in size and centromere position, they lack the genetic diversity found in homologous chromosomes.
What are Telomere?
Chromosomes consist of two arms that extend out from a specialized region of DNA , called Centromere. Centromere or primary constriction gives a particular shape to chromosomes due to its position. The chromosome extremities or terminal regions on either side are called telomeres.
What 2 substances do chromosomes consist of?
DNA and idk the other one or are you looking for chromosomes are composed of two chromatids held together by a centromere
