which of the following would not be considered a haploid cell? Which of the following is not true of homologous chromosomes? Which of the following statements is not true? In a species with a diploid number of 6, how many different combinations of maternal and paternal chromosomes would be possible in gametes?

What is true about homologous chromosomes?

The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations.

Which of the following is not true about homologous recombination?

3. Which of the following is NOT true about homologous recombination? Explanation: Homologous recombination involves a reciprocal exchange of sequences of DNA. 4.

Which of the following is true in homologous recombination?

Transcribed image text: Which of the following is not true of homologous recombination? Only occurs between regions of DNA sharing >50 basepairs of nearly identical sequence. Can repair a collapsed replication fork. Always accompanied by some loss of DNA sequence.

What is true of homologous chromosomes check all that apply?

What is true of homologous chromosomes? … One homologue is from the individual’s father, the other is from the mother. Homologous chromosomes are characteristic of diploid organisms. Information for the same trait is carried in the same location on homologues.

What are non homologous chromosomes?

This means that heterologous (non-homologous) chromosomes would, therefore, pertain to any two chromosomes that are different, such as in terms of gene sequence and loci. During meiosis, homologous chromosomes may naturally exchange genetic material. Heterologous chromosomes do not.

How do the four pairs of homologous chromosomes align and separate during meiosis?

How do the four pairs of homologous chromosomes align and separate during meiosis? They align and assort independently to form any of 16 different combinations.

When chromosomes do not segregate correctly during meiosis This is referred to as?

If chromosomes fail to segregate completely, it’s called nondisjunction and can result in the formation of gametes that have missing or extra chromosomes, according to “Molecular Biology of the Cell, 4th edition.” When gametes with abnormal chromosome numbers fertilize, most of the resulting embryos don’t survive.

What happens when pairs of homologous chromosomes separate during anaphase 1?

In anaphase I, centromeres break down and homologous chromosomes separate. In telophase I, chromosomes move to opposite poles; during cytokinesis the cell separates into two haploid cells.

Which is true of interphase?

Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. The prefix inter- means between, so interphase takes place between one mitotic (M) phase and the next.

What is true regarding eukaryotic chromosomes?

Eukaryotic chromosomes consist of DNA tightly wound around clusters of histone proteins. Chromatin consists of all the DNA in the nucleus, as well as its associated proteins. … The double helix shaped DNA molecule that makes up each chromosome is first coiled around clusters of histone proteins.
