D. Nucleic acids (RNA and DNA) are composed of a phosphate group , a pentose sugar (5 carbon sugar) and a nitrogen base (A,T,C,G).
Answer:
The answer is C, ligases.
Explanation:
The ligase chain reaction (LCR) is a method of DNA amplification. The ligase chain reaction (LCR) is an amplification process that differs from PCR in that it involves a thermostable ligase to join two probes or other molecules together which can then be amplified by standard PCR cycling (Barany, 1991).
Answer:
The expression of genes associated with drug resistance leads to the reduction in the effectiveness of drugs against cancer cells.
Explanation:
In cancer, drug resistance is produced when oncogenic cells are able to develop mechanisms of resistance against drugs such as, for example, chemotherapeutic agents. In these cases, therapeutic treatments become ineffective to fight against cancer cells and tumor progression. In consequence, it is imperative to trace the expression of target oncogenes associated with drug resistance in order to provide effective treatments to eliminate cancer cells.
The answer would be "production of gametes" or the first option. Is a mature haploid male or female germ cell which could collide with the opposite sex of the germ cell then for a thing called a zygote which is diploid cell that was formed because of the two gametes cells.
Hope this helps!
Answer is: <span>A. During crossing over, genetic information is exchanged between two homologous chromosomes.
</span>Crossing over results in recombinant chromosomes<span> during </span>sexual reproduction, <span>increases the genetic diversity of sexually reproducing organisms.
</span><span>In crossing over matching regions on matching chromosomes break and then reconnect to the other chromosome.</span>
