Explanation:) In mitosis, two genetically identical daughter cells are produced. Thus, the only possible combination of chromosomes is C1/C2/M1/M2/S1/S2 since all genetic material is inherited. b) The first meiotic division serves to split homologous pairs into two different cells, which are now haploid. There are 8 possible combinations of chromosomes (2 chromosomes for each homologous pair). For instance, a cell at this stage could inherit C1/M1/S1, or C2/M1/S1, or C1/M2/S1, etc. c) The same 8 combinations as above. The second meiotic division splits double-stranded chromosomes of each of these haploid cells into two daughter cells each so that only single-stranded chromosomes remain. Since no crossing over...

In the structure of glucose if the OH group on carbon atom 4 is above the plane of the ring then,it is alpha or beta or D glucos

WITCHER [35]

Answer:

The correct answer is May be alpha or beta.

Explanation:

Alpha D glucose and Beta D glucose structural configuration based the position of -OH group of C1 carbon or anomeric carbon.

if the C1 OH and C6 CH2OH are present in the same plane of the ring then the glucose molecule will exist in beta configuration.

On the other hand if C1 OH and C6 CH2OH are present in the opposite side of ring with respect to each other then the glucose molecule will exist in alpha configuration.

The position of -OH group of C4 atom above or down the plane does not matter for the structural appearance of glucose in alpha or beta configuration.

From that point of view it can be said that according to the question the glucose molecule will exist either in alpha or beta configuration.
