A strand of replicated DNA formed during prophase is a?
A replicated DNA strand formed during prophase is called a sister chromatid. Sister chromatids are two identical copies of a single chromosome that are joined at the centromere. These sister chromatids will later separate during cell division.
What is A strand of replicated DNA formed during prophase called?
A strand of replicated DNA formed during prophase is called a sister chromatid. Sister chromatids are identical copies of each other produced during DNA replication and are held together by a structure called the centromere.
What is a bivalent?
A bivalent refers to an antibody that can bind to two identical epitopes on an antigen. This dual binding enhances the antibody's ability to neutralize antigens and promote immune responses. Bivalency is a key feature of antibodies that contribute to their effectiveness in combating infections and diseases.
How many chromosomes does a swan have?
A swan typically has 80 chromosomes, which is the diploid number for this species. Chromosomes are found in the nucleus of cells and contain the genetic material necessary for proper cell function and reproduction.
What is cetromere?
The centromere is a region of a chromosome that plays a critical role in cell division. It is responsible for ensuring proper segregation of chromosomes during mitosis and meiosis. The centromere serves as the attachment site for spindle fibers that help pull apart sister chromatids.
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 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.
What is the term for the two sets of chromatids formed in the parent cell?
Tetrad
What is the meaning chiasmata and crossing over?
Crossing over:is a process of (breakage) and (exchange) of parts between two homologous chromatids .Each bivalent (a pair of same chromosomes ) is called a tetrad . Along the length of each bivalent one or more X shaped connections between (non-sister chromatids ) are found ;these CHIASMATA are places where crossing overs have occurred .I hope that's helped .ZIZO-Saudi Arabia
When do sister chromatids separates?
Sister Chromatids separate during anaphase.
What is the name of the structure that connects the sister chromatids?
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
If a diploid organism has 11 chromosomes how many pairs of sister chromatids does each cell possess?
Assuming it is not in the anaphase stage then the chromosomes had 22 sister chromatids. 1 chromosome has 2 sister chromatids.
What chromatids are attached at the centromere?
Sister chromatids are the chromatids that are attached at the centromere. Sister chromatids are two identical copies of a chromosome produced during DNA replication, and they remain attached until they are separated during cell division.
Do sister chromatids have the same genes within them?
Yes, sister chromatids have the same genes within them.
Do sister chromatids separate during mitosis?
Yes, sister chromatids separate during mitosis.
What is a cell structure that joins two sister chromatids of a chromosomes?
The cell structure that joins two sister chromatids into one single chromosome is called the centromere. This is at the center of the sister chromatids.
Why do sister chromatids cross over?
Sister chromatids dont over cuz they dont look it up lmfao
