question 8
DNA is copied into mRNA during the process of <u>Transcription</u>
- <u> </u>Transcription is the process by which information in the strand of DNA is copied into new molecule of messenger mRNA.
- The mRNA formed is a complimentary to DNA strand whereby replace of C with G, and A with U and T with A.
Question 9
Translation occurs in the ribosome , the organelle responsible for building proteins.
- Ribosome are responsible for protein synthesis.
- They receive messenger RNA sent from the nucleus and build protein.
- translation has three steps that is
- initiation - ribosome assemble around the target mRNA.
- elongation- The tRNA transfer amino acid to tRNA corresponding to the next codon.
- Three phases of translation initiation polymerase bind to DNA strand and move along until the small ribosomal subunit binds to DNA.
Is there a multiple choice or fill in the blank?
Answer:
it stayys on surfaces fir up to 2 weeks unless disinfected
Explanation:
Answer:
Option A, Glucose metabolism in the fetal brain increased
Explanation:
Usage of cocaine during pregnancy is prohibited. However, in case if cocaine is taken it disrupts the metabolism as it increases brain glucose metabolism to the level of an adult human being. Since glucose metabolism in brain is a sensitive process, any disruption in it can lead to unaccounted effects such as dysfunctional circulation, and pharmacological effect. Cocaine increases the dopamine by blocking the dopamine transporters thereby increasing the Vmax. Since the brain of a child has all kind of neurochemical components, cocaine intakes by a pregnant woman produces reinforcing effects in brain of fetus and also make it pharmacologically active
Hence, option A is correct
