Answer:
for differentiation
Explanation:
By gram staining, we can determine about gram-positive and gram-negative bacteria. If bacteria are Gram-positive then for further catalase test perform. If bacteria give catalase-positive then that's mean this bacteria is Staphylococcus. If bacteria give catalase-negative result then that's mean this bacteria is streptococcus.
The bacteria that are catalase-positive for their further identification coagulase test perform if bacteria is coagulase-positive that's mean it is staphylococcus aureus and if it is coagulase-negative that's mean that maybe differentiation saprophyticus or other species.
Answer:
Histone acetylation or DNA methylation.
Explanation:
The epigenetics may be defined as the genetic phenomena that might cause mutation in the organism's genome. The DNA sequence of the organisms do not get changed in epigenetics.
This phenomena is limited whether the gene is herited from the mother ot the father. The phenomena like acetylation of histones increase the gene expression. The DNA methylation and histone deacetylation at specific residues reduces the gene expression.
Thus, the answer is histone acetylation or DNA methylation.
Answer:
During meiosis, an event known as chromosomal crossing over sometimes occurs as a part of recombination. In this process, a region of one chromosome is exchanged for a region of another chromosome, thereby producing unique chromosomal combinations that further divide into haploid daughter cells.
Answer
Most of these techniques, including microarray analysis and reverse transcription polymerase chain reaction (RT-PCR), work by measuring mRNA levels. However, researchers can also analyze gene expression by directly measuring protein levels with a technique known as a Western blot.
