C
Punnett squares are only used for predictions, as they can’t accurately measure/county anything.
Answer:
D. RNA Polymerase
Explanation:
The enzyme RNA Polymerase is present during transcription, which is the process where DNA is transcribed into RNA to be later translated and give a protein. During transcription, RNA Polymerase synthesizes DNA using a strand of DNA as a template. In other words, it transcribes the DNA into RNA.
During replication, one strand of the DNA is replicated using a DNA strand as a template. The result is a new cell with the same information as the original cell. In this process, there is not RNA synthesis. If there is no RNA synthesis, there is no RNA polymerase.
Answer:
2n=46(duplicated)
Explanation:
Prior to cell division, which can either be meiotic or mitotic, the DNA content of the cell gets doubled in the Synthesis phase of the Interphase stage. In humans like myself, our cells consist of 23 pairs of chromosomes or 46 chromosomes. The DNA doubles in order for each daughter cell to get the correct number of genetic material.
After the S-phase, the chromosome number in the human cell does not change, just that each individual chromosome gets replicated or duplicated to form sister chromatids. Therefore, the human cell will contain 46 duplicated chromosomes or 92 sister chromatids after Synthesis phase and before the meiotic division.
Note that, humans are diploid organisms (2n) i.e. two set of chromosomes. Hence, they undergo meiosis to reduce their ploidy level from diploid (2n=46) to haploid (n=23).

Answer: Each cell is formed from a precursor cell. Blast cells are found in bone marrow. Blast cells are the precursors of blood cells like neutrophils,monocytes, lymphocytes, and erythrocytes. Usually blast cells are present in blood in low count.
High count of Blast cells shows abnormalities. As they are the precursors so high number of precursors cells shows less formation of blood cells. High count of Blast cells may lead to AML( Acute Myeloid Leukemia). AML patient have to go through CBC(complete blood count) Test to check abnormalities.
