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.
<span>The correct answers are zygote and fetus. This is correct because the initial joining of the sperm and the egg is called the zygote. The zygote is the first step in prenatal development that grows and transforms over months into the final form, a fetus. The fetus is the last form of the zygote prior to birth.</span>
Answer:
Rate of product formation is linear and [S] has not been lowered significantly.
Explanation:
The rate of enzyme-catalyzed reactions is affected by several factors, the contraction of substrates [S] is one of them. The substrate concentration keeps on changing as the reaction proceeds. This is why the reaction rate is measured at the initial stages of reactions when the substrate concentration [S] is much greater than the concentration of the enzyme. It is called the initial rate or initial velocity.
Under the conditions of higher substrate concentration and relatively much lower enzyme concentrations, only a few molecules of substrates are being converted into product. At a relatively higher substrate concentration, the rate of product formation increases linearly.
Enzymes are proteins that catalyze biochemical reactions within cells
