Autosomal and Sex Chromosome Difference, Chromatin and Chromosomes Difference?

The two autosomes in pairs are exactly the same size and morphology. Whereas sex chromosome pairs may not be consistent (XY males or ZW females).

The two autosomes in pairs are homologous in terms of DNA sequence, while the X and Y chromosomes are not exactly homologous.

One X chromosome in females becomes inactive in a heterochromatin state, while the Y chromosome in males becomes a heterochromatin state. Autosomes, on the other hand, do not heterochromatinize their entirety.

Sex chromosomes refer to the chromosomes that determine the sex of a biological being, and the chromosomes other than sex chromosomes are autosomes.

Answer A is the origin of the chromatin name copy;

The bai that answers b says is the composition of chromatin;

Answer C should be correct when it says that chromatin and zhi chromosomes are actually two states of the same substance at two different times;

Answer D is clearly wrong, chromosomes and chromatin are two different states of the same substance, the main components of which are DNA and protein.

Chromatin and chromosomes are different forms of the same substance.

It is the different forms of the same substance at different times.

A centromer is a chromosome, which includes two conditions:1Chromosomes that are not duplicated do not contain chromatids.

2.One chromosome after replication contains two chromatids. Those that do not have independent centromeres are called chromatids, and the two chromatids that share the centromeres are called sister chromatids.

Chromatids are for a single centromere that joins 2 pieces of DNA. For a chromosome connected to one DNA at a centromere, it can only be called a chromosome, not a chromatid. Hope to adopt. Thank you.

Autosomes refer to chromosomes in a chromosome set other than sex chromosomes. Of the 23 pairs of chromosomes in humans, 22 are autosomes, and the remaining pair is a sex chromosome made up of x and x or y chromosomes.

The two members of each pair of homologous chromosomes of autosomes are identical in morphology and size, and are similar in nature. It is stable in all individuals of each organism and in all its cells, but its number and morphology are germline-specific.

In the interphase nucleus, the morphology of chromatin is not uniform.

According to its morphology and staining characteristics, it can be divided into two types: euchromatin and heterochromatin.

Euchromatin: loose folding, low degree of condensation, in an elongated state, light coloration when dyed with basic dyes. Transcriptionally active chromatin is generally euchromatin.

Heterochromatin: high degree of folding and compression, in an agglutinated state, stained with basic dyes and darkened. Its DNA has many repeats and duplicates more than normal chromatin.

Some of the heterochromatin is agglutinated from the original euchromatin. There are also heterochromatins that are in a condensation state throughout the cell cycle, except for the replication phase.

1. Euchromatin: loose folding, low condensation, stretching; Heterochromatin: highly folded compression.

2. Euchromatin: light color when dyed with basic dyes; Heterochromatin: in the agglutinated state, subchromatic by basic staining.

3. The degree (density) of nucleic acid helix is different between the two.
