Cells with a full set of chromosomes are referred to as diploid or 2n, whereas cells with half the chromosomes are haploid or n. At which stage(s) of meiosis I are the cells diploid and at which stage(s) are they haploid

Answers

Answer 1

Answer:

Diploid → Prophase, metaphase, and anaphaseHaploid → Telophase

Explanation:

During prophase I,  chromosomes get condensed. Each of the chromosomes gets in pair with its homologous one. They do so to make the crossing-over possible, a stage where they interchange their parts → 2n

During metaphase I, each of the homologous pairs is driven to the equatorial plane, where they randomly line up → 2n

During anaphase I, occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair → 2n  

In telophase I, half of the chromosomes are already in one of the poles, while the other half is on the other pole. Each group of chromosomes has now half the number of the original cell. The nuclear membrane forms again in each pole → n

Finally, occurs cytokinesis, which involves the invagination of the cell membrane and cytoplasmic division.

The two new cells are ready for meiosis II.

Answer 2

Mitosis and Meiosis are the two types of cell division, in which the genetic material is replicated and transferred to the daughter cells.

The stages of meiosis in which chromosomes are diploid are prophase, metaphase, and anaphase. The haploid chromosomes are observed in telophase.

Meiosis is a reduction division in which genetic material is halved, such that a reduction in which diploid parent cells give rise to haploid daughter cells.

The stages of meiosis at which chromosomes are diploid and haploid are:

1. Prophase I is the first phase of meiosis I. The chromosomes are condensed and pair with the homologous chromosomes.

2. Metaphase I is characterized by the homologous pairs aligning at the equatorial plane.

3. Anaphase I is the independent separation of chromosomes, which migrate to opposite poles.

4. Telophase I is represented by the separation of chromosomes having a haploid number of chromosomes, which are now segregated into daughter cells.

Therefore, telophase I am the phase in which chromosomes are present in haploid numbers.

During phagocytosis of one cell to another, the larger cell engulfs the smaller cell by enclosing it in a part of its plasma membrane which then pinches off so the cell is then within the larger cell. Given this may have been the process that brought bacterial cells into the ancestors of eukaryotic cells as endosymbionts, what structural characteristics might be expected in mitochondria and chloroplasts?

Answers

Explanation:

Phagocytosis is the process by which cells ingest large particles, including other cells, by enclosing the particles in an extension of the cell membrane and budding off a new vesicle. During pinocytosis, cells take in molecules such as water from the extracellular fluid.

How did the CT enterography and the technetium scan lead to the correct diagnosis?

Explanation: CT enterography is a new non-invasive imaging technique that offers superior small bowel visualisation compared with standard abdomino-pelvic CT, and provides complementary diagnostic information to capsule endoscopy and MRI enterography. CT enterography is well tolerated by patients and enables accurate, efficient assessment of pathology arising from the small bowel wall or surrounding organs. This article reviews the clinical role of CT enterography, and offers practical tips for optimising technique and accurate interpretation.

The following RNA strand was produced: 5 AUG GCG UUU 3 Which of the following DNA strands could have been the template for this RNA? Choose 1 answer: A 3 TAC CGC AAA 5' 3' CGT TAT GGG 5' 3' AUG GCG UUU 5' 3' UAC CGC AAA 5​

Answers

Answer:

A

Explanation:

Each nucleotide is appropriately paired according to the A-U/T-A and C-G pairing rules, so these are complementary strands.

The DNA strand that could have been the template for RNA 5' AUG GCG UUU 3' is 3' TAC CGC AAA 5'.Thus, the correct option is A.

What is a Template strand?

A template strand may be defined as the DNA sequence that can duplicate itself during the process of mRNA synthesis. During this process, the cell utilizes a non-coding/antisense DNA sequence as a template to construct mRNA.

The production of the mRNA strand is done with the help of complementary base pairing with that of the template strand. In this process, A is bound to T and vice versa, while C is bound to G and vice versa.

In mRNA, the Thymine (T)  is replaced by Uracil (U). According to Chargaff's rule, the amount of ADENINE is equal to THYMINE, while the amount of GUANINE is equal to CYTOSINE.

Therefore, it is well described above.

anatomy and neurobiology

Explanation:

Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.

Successful molecular biologists have an excellent understanding of subjects such as cell physiology, chemistry, genetics, and physics.

A neuroscientist (or neurobiologist) is a scientist who has specialised knowledge in the field of neuroscience, the branch of biology that deals with the physiology, biochemistry, psychology, anatomy and molecular biology of neurons, neural circuits, and glial cells and especially their behavioral, biological, and psychological aspect in health and disease.
