What is the difference between chromosomes chromatids and homologous chromosomes quizlet?
chromosome is DNA tightly coiled around histones (proteins) homologous chromosomes are two different copies of the same chromosome, and sister chromatids are two identical copies of a chromatin connected by a centromere.
What are the two main differences between sister chromatids and homologous chromosomes?
Sister chromatids are used in cell division, like in cell replacement, whereas homologous chromosomes are used in reproductive division, like making a new person. Sister chromatids are genetically the same. That is, they are identical copies of one another specifically created for cell division.
What are homologous chromosomes quizlet?
Homologous chromosomes are chromosome pairs, one from each parent, that are similar in length, gene position and centromere location. … Homologous chromosomes are similar but not identical. Each carries the same genes in the same order, but the alleles for each trait may not be the same.
What is meant by homologous chromosomes?
Homologous chromosomes: A pair of chromosomes that contain the same gene sequences, each derived from one parent.
What is relation between chromatin chromatid and chromosomes?
Chromatin is the thread like structure which is genetic material of chromosomes consisting of DNA and protein. It is found in interphase stage of the mitotic cycle. Chromatid is the each single stand of duplicated chromosome, is attached with the other duplicate part with the centromere.
