The karyotype of one species of primate has 48 chromosomes. In a particular female, cell division malfunctions, and she produces

one of her eggs with an extra chromosome (25). The most probable source of this error would be a mistake in which of the following?A) Mitosis in ber ovary B) Metaphase I of one meiotic event C) Telophase II of one meiotic event D) Telophase I of one meiotic event E) Either anaphase I or II

Answer:

E) Either anaphase I or II

Explanation:

Failure of segregation of homologous chromosomes during anaphase I or failure of segregation of sister chromatids during anaphase II leads to the presence of the abnormal number of chromosomes in resultant gametes. In the given example, the egg mother cell with 48 chromosomes (24 pairs) would enter meiosis I but the failure of one pair of homologous chromosomes to segregate from each other followed by normal meiosis II would result in the formation of two gametes with one extra chromosome and two gametes with one less chromosome.

On the other hand, if the nondisjunction occurs at anaphase II of meiosis II, two normal gametes, one gamete with one extra chromosome and one gamete with one less chromosome will be formed. Therefore, nondisjunction at anaphase I or anaphase II would have resulted in the production of eggs with one extra chromosome.

brilliants [131]

Answer:

Some organisms have a tremendous amount of noncoding DNA, like repetitive sequences.

Explanation:

DNA is the genetic material in almost all the living organisms but except in case of viruses that has RNA as their genetic material. DNA consists of the four nitrogenous bases, pentose sugar and phosphate group.

Prokaryotes have simple body organization and structure because of the sall amount of DNA. Eukaryotes have complex body organization because they have large amount of the transposons, repetitive sequences and non repetitive DNA sequences.

Thus, the correct answer is option (b).

Answer:

units of C 6 H 12 O 6

Explanation:

Starch is a polymer of billions of glucose units joined through a condensation reaction that splits out molecule of water. Starch is an important part of our food belonging to the category of carbohydrates. It is found in cereals and potatoes.

Starch can be in two forms based on the their structure and some other differences:

1) Amylose- straight chain polymer

2)Amylopectin- Branched chain polymer

You can see the structure of starch with glucose monomers for better understanding in the image.


Hope it helps!
