What is the composition of a bivalent at the beginning of prophase 1?
A bivalent at the beginning of prophase I is composed of two homologous chromosomes that have already replicated into sister chromatids. Each homologous chromosome consists of two sister chromatids joined by a centromere. The bivalent forms as the homologous chromosomes pair up and undergo synapsis.
Synapsis forms a chromosome complex known as a?
bivalent
What structure is formed by two sister chromatids being held together by a centromere?
A bivalent.Sister chromatids are normally joined at the centromere. When homologous chromosomes pair, the two sister chromatids of one chromosome join with the two sister chromatids of the other chromosome. So it is really the joining of non-sister chromatids that is special.The word "bivalent" refers to the temporary combining of the two chromosomes (four chromatids). The bivalent forms in prophase I of meiosis, and is split in anaphase I.
What is the condensed form of DNA referred as?
The highly condensed forms of DNA (and proteins) are known as chromosomes.
DNA is packaged into structures called?
Answer:chromatin not chromosomes. :DIt Is Chromosomes Not Chromatin:]
What forms from a pair of homo logs during prophasee 1?
In prophase 1 the pair of homologous Chromosomes come together to form a tetravalent or bivalent, which contains four chromatids.

How many sister chromatids are in a bivalent?
A bivalent contains two duplicated homologous chromosomes.

What is the composition of a tetrad at the beginning of prophase you?
One pair of homologous chromosomes. One chromosome in a tetrad is paternally inherited, while the other is maternally inherited. Each chromosome consists of two chromatids.
Where can i find duplicate W2 forms for bayada home health?
I n duplicate copy of my w2 for bayada home health
What is the name given to a pair of chromosomes that have matching locations for alternate forms of the same gene?
homologous chromosomes
What is the condensed form of DNA referred as?
The highly condensed forms of DNA (and proteins) are known as chromosomes.
What phase of the cell are these cells in?
The five cell cycles are: Telophase (Cell wall pinches in, nuclear membranes are formed, two daughter cells are produced.) Interphase (You can cell the nucleolus, you can see uncoiled chromatin, you cannot see chromosomes.) Prophase (Chromatin uncoils, chromosomes appear, chromosomes duplicate to form sister chromatids, spindle forms between centrioles.) Metaphase (Chromosomes move to the middle of spindles.) Anaphase (Sister chromatids are pulled to opposite sides of cell, each chromatid is now a chromosome.)
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.
