14: Operons allow prokaryotes to replicate DNA at the appropriate time.
Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon.
15. The central dogma of molecular biology is:
DNA to RNA to Proteins
Protein Synthesis occurs in 3 steps.
First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.
The answer is C I don’t think this needs more explanation but if needed just ask!
Answer:
did you already get the answer or you still need help
Answer:
That enhances the sensitivity of cancerous tumor cells toward the applied radiation dose.
Explanation:
It is a known fact that tumor cells are very hard to treat so, to increase their sensitivity toward radiation, the body of the patient is treated with special kind of cytotoxic drugs that enhance the sensitivity or exposure of those cancerous cells toward radiation and made them vulnerable. These drugs are applied to modern approaches because of their extensive action toward tumor cells.
In nondisjunction, if members of a pair of homologous chromosomes do not move apart during meiosis I or sister chromatids fail to separate during meiosis II, this means one gamete receives 2 of the same kind of chromosome and i<span>f either one of these abnormal gametes unites with a normal one at fertilization, the zygote will also have an abnormal number of particular chromosomes; which is known as an aneuploidy.</span>
