what is the difference between replicated and unreplicated chromosomes?
531503
An unreplicated chromosome contains one double strand -DNA molecule. A replicated chromosome contains two identical double strand -DNA- molecules, the chromatids, that are joined at their centromere. ... (The sex chromosomes present in each human cell are an exception).

Within one chromosome, what is the relationship between the sequence of bases in DNA of one sister chromatid compared to the other? the sequences are identical. DNA replication occurs?

Homologous chromosomes contain the same gene loci but may have different alleles of a particular gene. Sister chromatids are identical copies of each other produced during DNA replication. ... Sister chromatids are only formed during mitosis. Homologous chromosomes are formed during meiosis.

Simply put, sister chromatids are two copies of the exact same chromosome and they have the exact same DNA . ... Homologous chromosomes, on the other hand, are the same chromosomes from different cells that may or may not have different DNA. For example, your chromosome 13 and my chromosome 13 are homologous.

​Chromatid A chromatid is one of two identical halves of a replicated chromosome. ... Following DNA replication, the chromosome consists of two identical structures called sister chromatids, which are joined at the centromere.

Although both are very similar, the difference between the two is the pairing. Homologous chromosomes are basically two similar chromosomes inherited from father and mother. They are homologous because they have the same genes, though not same alleles. ... When they do so, the homologous pair becomes known as a bivalent.

A diploid cell starts with 2N chromosomes and 2X DNA content. After DNA replication, the cells is still genetically diploid (2N chromosome number), but has 4X DNA content because each chromosome has replicated its DNA. Each chromosome now consists of a joined pair of identical sister chromatids.

Homologous chromosomes and sister chromatids are both identical copies of each other. ... Homologous chromosomes contain the same gene loci but may have different alleles of a particular gene. Sister chromatids are identical copies of each other produced during DNA replication.

Mitosis only separates the newly replicated chromosomes; DNA replication does not occur during mitosis. The big problem with eukaryotes is that they have to replicate linear chromosomes with special ends called telomeres.

Which statement is correct concerning the relationship between chromosomes and chromatids? A replicated chromosome contains two sister chromatids. A replicated chromosome contains a single chromatid.

In a tandem duplication, duplicated regions are arranged next to each other on the same chromosome by nonallelic homologous recombination (Fig. 1, top). In translocated duplications, chromosomal duplications are translocated onto another chromosome by break-induced replication (Fig.

Here is the difference: Replication is the process of creating a glass master and stamper of your data (CD Audio, CD-Rom, DVD video) then injection moulding the discs using that stamper. Duplication is the process of taking blank, recordable discs (CDRs or DVDRs) and writing the information on them with a laser.

Generally, biological replicates are defined as measurements of biologically distinct samples that show biological variation (21). In contrast, technical replicates are repeated measurements of the same sample that show independent measures of the noise associated with the equipment and the protocols.

Two different mechanisms do this in cells: Bacterial cell fission, in which the circular chromosome is replicated. Eukaryotic cell cycle, including Mitosis, in which multiple linear chromosomes are separated and passed on.

Simple, or conservative transposition, is a non-replicative mode of transposition. That is, in conservative transposition the transposon is completely removed from the genome and reintegrated into a new, non-homologous locus, the same genetic sequence is conserved throughout the entire process.

Sister chromatids are 2 copies of a single chromosome and so are genetically identical (they also are physically attached to one another). ... Homologous chromosomes are 2 physically different chromosomes that have the same genes but are not genetically identical.

The major difference between the chromosome and autosome is that, every autosome is a chromosome, whereas all chromosomes are not autosomes. ... Autosomes have homologous pairs, whereas some chromosomes have different pair: in a male, sex is determined by the XY.
