What does a replicate chromosome consist of?
A replicated chromosome consists of an exact copy (assuming no mutations) of the original chromosome, which is composed of DNA and proteins called histones.
Do alleles consist of Many genes?
No, alleles do not consist of many genes. An allele is a specific variant of a gene that occupies the same position on a chromosome as another variant of that gene. While a gene can have multiple alleles, each allele represents a single version of that gene, rather than a collection of multiple genes.
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 are found in pairs?
Humans typically have 23 pairs of chromosomes, totaling 46 chromosomes. These pairs consist of 22 pairs of autosomes and one pair of sex chromosomes, which are XX in females and XY in males. Each chromosome in a pair carries similar genetic information, with one chromosome inherited from each parent.
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.
How is gene and DNA related?
chromosome consist of gene
What does a replicate chromosome consist of?

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 chromosome consist 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.
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
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.
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 name is given to a unit of a bacterial chromosome that controls the expression of a specific set of genes?
The unit of a bacterial chromosome that controls the expression of a specific set of genes is called an operon. Operons consist of a promoter, operator, and genes that work together to regulate gene expression in bacteria.
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.
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.
What is the simplest level of packing of the eukaryotic chromosome?
The simplest level of packing of the eukaryotic chromosome is the wrapping of DNA around histone proteins to form nucleosomes. Nucleosomes consist of DNA wrapped around a core of histone proteins, which serves as the basic unit of chromatin packaging in eukaryotic cells.
When chromosomes become visible at the beginning of cell division what does each chromosomes consists of?
