what is a difference between chromosomes and sister chromatids?
311692
A chromosome is made up of a single, double-stranded DNA molecule while a chromatid comprises of two DNA strands joining collectively by their centromere. The chromatids contain a substance called chromatin. ... In the case of chromatids, each sister chromatid is an exact replication of the other.

Because DNA has already replicated (during S phase of interphase) when it coils into a chromosome, each chromosome actually consists of two identical copies. The two copies of a chromosome are called sister chromatids.
1267114
Each chromosome is made up of two identical sister chromatids. ... Tetra- stands for four; hence, there are four sister chromatids. Tetrads do not appear in mitosis because there is no crossing over event. In mitosis, the chromosomes are brought to the equator of the cell without crossing over.

CHROMOSOMAL STRUCTURE A chromatid is a condensed DNA subunit of a chromosome. The two chromatids of a duplicated chromosome are held together at a region of DNA called the centromere (see figure below).

37) What is the difference between the chromosomes in a secondary spermatocyte and those in a spermatid? A) The chromosomes in secondary spermatocytes consist of two chromatids; the ones in the spermatid consist of only one chromatid. B)

Sister chromatids are genetically the same. That is, they are identical copies of one another specifically created for cell division. ... On the other hand, a pair of homologous chromosomes consists of two non-identical copies of a chromosome, one from each parent.

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 meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas Meiosis I produces 2 diploid daughter cells.

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.
1346857
Sister chromatids are by and large identical (since they carry the same alleles, also called variants or versions, of genes) because they derive from one original chromosome. ... Homologous chromosomes might or might not be the same as each other because they derive from different parents.
1215293
The chromosome is made up of two identical structures held together by a centromere. Each of these identical structures is known as chromatids. ... Sister chromatids are identical pieces of DNA held together by a centromere and pulled apart during cell division to make new identical chromosomes in the newly made cells.
507392
A full set of sister chromatids is created during the synthesis (S) phase of interphase, when all the chromosomes in a cell are replicated. The two sister chromatids are separated from each other into two different cells during mitosis or during the second division of meiosis.
774895
Sister chromatids always start off identical, because they result from DNA replication; the DNA of both of the two sister chromatids is identical to the DNA molecule that was replicated, and so the two chromatids are also identical to each other.
324987
Sister chromatids are used in cell division, like in cell replacement, whereas homologous chromosomes are used in reproductive division, like making a new person. ... On the other hand, a pair of homologous chromosomes consists of two non-identical copies of a chromosome, one from each parent.
434905
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I.

How do homologous chromosomes differ from sister chromatids? Homologous chromosomes are the two chromosomes that make a chromosome pair. A sister chromatid is the duplicate of each of the pair of homologous chromosomes. Each of the chromosomes that make up the homologous pair is derived from each parent.
413888
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.
