describe the process of reading a gene and turning it into a protein in a eukaryote.Your first paragraph should summarize transcription and your second paragraph should summarize translation.

What is a gene? What does "base sequence" mean? If the base sequence of a segment of a molecule of DNA is changed, will the base sequence of the mRNA made during transcription be changed? If the base sequence of the mRNA is changed will the sequence of amino acids obtained during translation change? If the primary structure of a protein is changed, will it's function change? If the function of the protein changes, will the organism have a different characteristic? Do introns get read during translation?

What are two advantages for circularizing the mRNA during the process of eukaryotic translation?  (Select two correct answers)   mRNA circularization ensures that translation terminates at the proper termination codons. mRNA circularization facilitates the binding of the ribosome to the Shine-Dalgarno sequence. mRNA circularization ensures that a full-length mRNA is used in the process of translation. mRNA circularization eliminates the requirement for translation factors in the process of translation initiation. mRNA circularization allows for a more efficient re-initiation of the translation process during repeated cycles of translation.

Which of the following is observed in prokaryotes but not in eukaryotes?     An mRNA can be translated by only one ribosome at a time in prokaryotes.   The 5´ end of a prokaryotic mRNA can be translated while the 3´ end is still being transcribed   In prokaryotes, ribosomes move along an mRNA in the 3´ to 5´ direction.   UGG is an example of a stop codon only found in prokaryotes.

Complete the following table: Type of RNA Functions Transfer RNA (tRNA)     In a ribosome, plays a structural role;as a ribozyme, plays a catalytic role(catalyzes peptide bond formation) Primary transcript   Small RNAs in the spliceosome

DNA gene TAC AGC TTT mRNA codon (No thymine in RNA!)       tRNA anticodon (No thymine in RNA!)       Amino acid Use the mRNA with the Genetic Code.       Use the mRNA with the Genetic Code. Answer the questions below.   Questions How many nucleotides would be needed to code for a protein that has 100 amino acids?   Using the Genetic Code in Table 6.3, write all of the possible codons that signal the start and end of a gene. Start: End: An amino acid sequence of a protein molecule includes methionine, lysine, serine and glycine. Show each different codon that could result in each of these amino acids. You will have more than one codon for all of them except methionine. Amino Acids All Possible Codons Methionine   Lysine   Serine (Look carefully. There are six possibilities)   Glycine   Question 3 illustrates the redundant nature of the genetic code. Can you think of an advantage of having several codons that all code for the…

Can you help me to explain to me because i struggled with my homework?

The following mRNA transcript would result in which polypeptide sequence? 5'-ACU UUC ACU AUG UUU UUA UCC UCC ACU CCU UGA-3' Use the following codons and the amino acids they encode: AUG = Start or Met; UUU, UUC = Phe; UUA, UUG = Leu; UCU, UCC = Ser; CCU, CCC = Pro; ACU, ACC = Thr; UGA = Stop. Select one: O a. Phe-Leu-Ser-Ser-Thr-Pro O b. Met-Phe-Leu-Ser-Ser-Thr-Pro O c. Thr-Phe-Thr-Phe-Leu-Ser-Ser-Thr-Pro Od. Met-Phe-Leu-Ser-Ser O e. Thr-Phe-Thr

Which of the following is observed in prokaryotes but not in eukaryotes? O In prokaryotes, ribosomes move along an mRNA in the 3' to 5' direction. An MRNA can be translated by only one ribosome at a time in eukaryotes. Translation does not require any protein factors in prokaryotes. TCC is an example of a stop codon only found in prokaryotic mRNA. An MRNA can be translated by only one ribosome at a time in prokaryotes. The 5' end of a prokaryotic MRNA can be translated while the 3' end is still being transcribed.

Which of these molecules has multiple partial charges and thus is most soluble in water? B H HHH HHH ABCD or E CH H CHOH D CH OH A cell is specialized in producing oil and steroid hormone. Which structure would be found in large r cell? O vacuoles O peroxisome O rough endoplasmic reticulum O smooth endoplasmic reticulum The oxygen released from photosynthesis results from: Reduction of NADP* to NADPH Chemiosmosis Oxidation of water Photophosphorylation
