What is the point of attachment between two chromatids?
The point of attatchment between two chromatids is called the centromere. When two chromatids are connected, it is called a chromosome which is essential in DNA replication, or, mitosis.
Do some trapezoids have two pairs of parallel side's is that true?
Trapezoids have only one pair of parallel sides. A parallelogram has two pair of parallel sides.
What has four sides in all one pair of parallel lines two right angles?
A trapezoid has one pair of parallel side and can have two adjacent angles that are right.
The point at which two chromatids joined is called what?
centromere
Do rectangles have exactly one pair of opposite side parallel?
They have two pairs of sides that are parallel. Trapeziums have exactly one pair of sides that are parallel.
How many centromere hold together two chromatids?
1 centromere for every pair of chromatids
What two identical bodies make up a duplicated chromosome?
Somatic cell chromosome is made of two identical chromatids
What is the term for the two sets of chromatids?
The term for the two sets of chromatids is sister chromatids. Sister chromatids are two identical copies of a single chromosome formed during the S phase of the cell cycle.
How many chromatids are involved in crossing over of a homologous pair of chromosomes?
Crossing over involves the exchange of genetic material between homologous chromosomes during meiosis. Each homologous pair consists of four chromatids (two from each chromosome), and crossing over occurs between a pair of chromatids from each homologous chromosome. This results in the exchange of genetic material between the chromatids.
How many sister chromatids are in a bivalent?
A bivalent contains two duplicated homologous chromosomes.
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 only a single member of a pair of chromosomes present in a cell?
A single member of a pair of chromosomes in a cell is known as a haploid. Haploid cells contain only one set of chromosomes, typically found in reproductive cells such as eggs and sperm. This is in contrast to diploid cells, which contain two sets of chromosomes.
How does a single pair of sister chromatids differ from a single unduplicated chromozone?
Sister chromatids are two copies of a replicated chromosome. Chromosomes occur in pairs. These will be separated in anaphase of mitosis and one chromatid pair will be left for each daughter cell.
Which are the two main parts that make up a chromosome?
A centromere and a pair of sister chromatids
What is the difference between a chromatid and a sister chromatid?
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
Traits are determined by pairs of genes called?
Traits are determined by pairs of genes called alleles. Each gene in a pair can have different variations (alleles) that can influence the expression of a trait in an individual.
How does a tetrad form in prophase I of meiosis?
In prophase I, doubled homologous chromosomes group together to form a tetrad.
