- Explain why the answer is correct. For eukaryote cells to evolve into new types of eukaryotic organisms, which of the following would one expect to occur? The correct answer is E a) these cells have evolved because they have different DNA because of mutations b) Their endoplasmic reticulum is synthesizing new and/or different proteins. c) These specialized cells activate new genes to synthesize new proteins. d) these organisms have new characteristics because they have acquired new genes. e) all of these are truearrow_forwardThe Selfish Gene is a radical theory that argues that all living creatures are essentially vehicles for their genes- hence, we all are a “survival machine" for our genes. In the light of what you have learned about the molecular structure and function of the gene, is this perspective still relevant? Cite specific biological phenomena to prove your point. References:arrow_forwardBelow are the steps of protein synthesis. What is the correct sequential order? 1. MRNA is formed with codons as product of transcription. 2. Codons are translated and polypeptide chain is transferred. 3. mRNA moves into cytoplasm and becomes associated with ribosomes. 4. DNA in nucleus serves as a template. 5. Anticodon - codon complementary base pairing occurs with tRNA and MRNA. * 4, 1, 3, 2, 5 4, 3, 1, 5, 2 O 4, 1, 2, 3, 5 O 4, 1, 3, 5, 2arrow_forward

- An astrobiologist discovers a new form of life on another planet. Life here appears to have evolved using DNA as the information storage molecule and proteins to carry out cellular function, much like on Earth, however the individual building blocks on this planet are different. On this planet, there appear to be 3 different nucleotides in the DNA and 30 different amino acids in the proteins. Which of the following conclusions about this form of life would be most justified? These organisms can produce proteins no more than 30 amino acids in length. These organisms must produce 30 different forms of mRNA Amino acids must be coded by sets of 3 nucleotides in the DNA of the organisms on this planet. Amino acids must be coded by sets of at least 4 nucleotides in the DNA of the organisms on this planet. These organisms cannot produce more than 30 kinds of protein.arrow_forwardWhich of the following is true for the tRNA of eukaryote cells? tRNA is a) made of DNA and protein, b) the active site in carbohydrate synthesis, c) is a subunit that forms mRNA from the codon of DNA. d) found inside the endoplasmic reticulum, e) has the specific sequence of bases (anti codon) that interacts with the base sequence (codon) of mRNA.arrow_forwardE. coli would be a good model organism for which of the following processes? a) DNA replication b) how mitochondria get distributed to daughter cells during cell division c) how cells decode their genetic instructions to make proteins (translation) d) a and c e) a, b and carrow_forward
