A chromatid is one of two identical halves of a replicated chromosome. During cell division, the chromosomes first replicate so that each daughter cell receives a complete set of chromosomes. Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.

Answer to: After the S phase of mitosis, a replicated chromosome consists of a. a chromosome tetrad. b. four sister chromatids. c. two sister

In each revertant, the BamHI restriction pattern detected by Southern blot hybridization using an ATCase coding sequence probe consists of two bands, the one corresponding to the ura2 15-30-72 resident copy, which is preserved at its locus, and the other to a duplicated copy inserted into a novel chromosomal … 2016-10-20 Answer to: After the S phase of mitosis, a replicated chromosome consists of a.

A duplicated chromosome consists of two _____. sister chromatids. •A duplicated chromosome consists of two identical structures called chromatids.

Meiotic divisions include two nuclear divisions that produce four daughter nuclei that are genetically different and have one chromosome set instead of the two sets of chromosomes in the parent cell. The main differences between the processes occur in the first division of meiosis, in which homologous chromosomes are paired and exchange non-sister chromatid segments.

A)centromeres B)centrosomes C)genomes D)sister chromatids Expert Answer.

two sister A duplicated eukaryotic chromosome takes on an "X" shape when _____. a. sister chromatids condense b. the DNA breaks c. DNA replication is occurring Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz). A duplicated chromosomes consists of two identical structures called chromatid (KROH-muh-tidz).

In humans, the centromere contains ~1 million base pairs of DNA. Most of this 2012-02-18 · A duplicated chromosome consists of two____.? a. centrosomes.

Each separated chromosome consists of a single chromatid  During this time, the two sister chromatids from the replicated chromosomes Each gamete formed contains a haploid genome consisting of 23 chromosomes. So prior to cell division, the chromatin condenses. This prevents the DNA from getting tangled up when it is sorted into two cells during mitosis. Copying  condense & coil, the chromosomes the chromatids apart appearing as linear consisting of microtubules form at form two new cells.
