Dr Peter Fraser of the Babraham Institute explains. Generally plants have larger chromosomes than animals. View Feedback Question 2 How is it possible that each daughter cell during cell replication receives an identical copy of the DNA.

The theory was proposed by Boveri-Sutton. Unlike eukaryotic cells prokaryotic cells dont have a membrane-bound nucleus. The length of a chromosome varies from 01µ to about 30 µ and the diameter 02 µ to 2 µ.

What is the presence of three chromosomes instead of two called and what human chromosome is most commonly affected in this fashion. The long arm of the chromosome is labeled the q arm. Metaphase or early anaphase is the best condition to observe the shape of the chromosome in an organism cell.

Over and states that Mendelian genes have specific loci on chromosomes which undergo segregation and independent assortment. Each chromosome contains a molecule of DNA that is wound tightly around clusters of histone proteins. A prokaryotic cell typically has only a single coiled circular chromosome.

The chromosomes are generally rod-like and acrocentric sometimes like V-shaped as amphibians. An X D. Homologous chromosomes pair up and non-sister chromatids exchange genetic material.

Reproductive cells have 23 chromosomes. The number and types of chromosomes present in a cell are called a. A male or female gamete 2 Which statement best describes the process of crossing over1 point A.

Chromosomes are classified into four types by their shape in metaphase or in anaphase which in turn is determined by the position of the centromere. Homologous chromosomes have the same shape size and carry the same type of genetic information. A fertilized cell B.

B Genes are segments of DNA which form tight coils called. A place where genetic information is stored C. Asked by wiki 27102021 in Biology viewed by 154 People.

A chromosome is the entire set of genetic instructions for a eukaryotic cell. A chromosome contains two copies of each allele possessed by an organism. A chromosome consists of multiple genes that code for inheritable traits.

At the most basic level a chromosome is a molecule of DNA that is tightly coiled around proteins called histones. Chromosomes contain thousands of segments called A. What was the most likely conclusion of Morgans research.

What shape best describes most chromosomes. The DNA inside the nucleus is organized into chromosomes. ExplanationDuring cell division the identical copies called a sister chromatid pair are joined at the region called the centromere 2.

Once the paired sister chromatids have separated from one another in the anaphase of mitosis each is known as a daughter chromosome. Which best describes the relationship between DNA genes and chromosomes. Rod-like and have a centromere situated on the proximal end.

What phrase describes an individual with two dominant alleles. Eukaryotic cells have multiple chromosomes that are linear in shape. In this stage they become thick and filamentous.

Which best describes the relationship between dna genes and chromosomes. DNA is replicated individually in each new cell. Instead their genetic material can be found in a region of the cytoplasm called the nucleoid.

A DNA are segments of genes which form tight coils called chromosomes. What is created when chromosomes are paired by. They are most clearly visible during metaphase stage of cell division.

Crossing-over allows for the exchange of genetic material and produces unique combinations of alleles. When does the spindle apparatus first form in meiosis. The image of a chromosome an X-shaped blob of DNA is.

It describes linkage recombination and crossing. Each chromosome has a constriction point called the centromere which divides the chromosome into two sections or arms. The short arm of the chromosome is labeled the p arm.

An octagon 4 27. Prokaryotic chromosomes are found in the nucleoid of prokaryotic cells and they are circular in shape. What best describes the sex chromosomes in humans.
