Answer:
The correct answer will be the cell is in prophase I of meiosis and will enter metaphase I next.
Explanation:
Meiosis is a type of cell division which is involved in the formation of haploid gametes.
During meiosis the division of the genetic material is markedly observed and based on this meiosis is divided into 4 phases: prophase, metaphase, anaphase and telophase.
During prophase: the chromatin structure of DNA starts condensing to form chromatids which attaches to homologous chromatids and are known as sister chromatids. These sister chromatids exchange their genetic material via a process called called recombination or crossing over which takes place during pachytene stage of prophase I. After crossing over it is proceeded by the next stage that is metaphase I in which chromosomes gets aligned at the center of the cell.
Thus, the cell is in prophase I of meiosis and will enter metaphase I next is the correct answer.
DNA is a chain of nucleotides bonded together. On that chain there are particular portions of it that the sequence of the nucleotide codes for particular proteins; this is known as a gene. In eukaryotric cells, DNA is coiled around proteins such as histones to form chromatids which when two join at the centre by a centromere to form a chromosome.
Answer:
The answer to the question is C
Explanation:
It is used for all I and II and III
Answer:
Option (3).
Explanation:
Batch culture may be defined as a type of culture which are refereed as stack and operated as influx of the reactant up to the maximum level. This technique is generally used to grow the micro organisms.
The cell mass do not decrease or increases as the cell divides in the batch culture. The new batch are added during the culturing process. The cell mass remains constant in batch culture.
Thus, the correct answer is option (3).
