What holds homologous chromosomes together?
Homologous chromosomes are held together by a protein structure called the synaptonemal complex during meiosis. This complex helps align the chromosomes and facilitate genetic recombination between homologous chromosomes.
Copies of chromosomes liked together at their centromeres at the beginning of meiosis are called what kid of chromatid?
At the beginning of meiosis, copies of chromosomes linked together at their centromeres are called sister chromatids. These sister chromatids are duplicated copies of a single chromosome and are held together by proteins called cohesins.
When the chromosomes make an exact copy of themselves what are they then called?
When chromosomes make an exact copy of themselves, they are called sister chromatids. Sister chromatids are identical copies of a chromosome that are held together by a structure called the centromere.
What structures hold the chromosomes together?
A chromosome is made up of different parts: nucleotides (base pairs), sugar and phosphate (a full chromosome contains other stuff too but that is for a more complex explanation). The nucleotides are what codes for proteins, so that is the useful or 'coding' information. The sugar and phosphate form a sugar-phosphate backbone, holding all of the nucleotides together. (type base pairs into Google image to find a picture of this). A Chromosome is a long strand of these nucleotides which are held together with the sugar-phosphate backbone. IF UR TALKING ABOUT MEIOSIS then they are held together by spindle fibers.
What are the links between DNA genes chromosomes and proteins?
Chromosomes are long strands of DNA which are held together by proteins.
What are homologous pair held together with?
Homologous pairs of chromosomes are held together by a structure called the synaptonemal complex during meiosis. This complex facilitates the pairing and alignment of homologous chromosomes, allowing for genetic recombination or crossing over. Additionally, cohesion proteins help maintain the connection between sister chromatids within each homologous chromosome.
When one chromosome of a homologous pair replicates the two identical copies are referred to as what and are held together by what?
They are held together by centrioles and I think you're referring to the daughter chromosomes..
What is sister chromatids held together by?
Sister chromatids are held together at a region of highly condensed DNA called the centromere. The centromere region is very important during the process of cell division where chromosomes have to segregate into daughter cells. In addition, chromosomes are classified into different groups based on the position of the centromere
Where are chromatic held together?
Chromatics are held together at a region called the centromere
What is the period during witch chromosomes duplicate is?
Chromosomes duplicate during the S phase of interphase in the cell cycle. This is when DNA replication occurs, resulting in each chromosome being duplicated to form two sister chromatids held together at the centromere.
The replicas of chromosomes that form during prophase are called what?
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.
A structure having two chromatids held together at a centromere?
This structure is called a chromosome. Chromosomes contain the genetic material of a cell and are replicated before cell division to ensure that each daughter cell receives a complete set of chromosomes. The two chromatids are identical copies of the same DNA molecule.
