1. Cells contain DNA, which contains the universal genetic code/instructions for all processes in all organisms on Earth. There are multiple structures important to storing this genetic material. Which of the following correctly places these structures in order from smallest to largest? (1 point) |
O cell, DNA, chromosome, nucleus, gene
O gene, DNA, chromosome, nucleus, cell|
O DNA, gene, cell, chromosome, nucleus
O gene, nucleus, chromosome, cell, DNA
With ofguanine, mA however does not ontin thyrine, What bas on the mo, matches up with the adenine on the DiA tandr (The vide does not say Ihs bor
OU (uracil)
O G (guanine)
O A (adenine)
O C (cytosine)
3. Transcription results in: (1 point)
• a protein
• a tRNA strand
• an mRNA strand
• a new DNA strand
4. What is the role of the ribosome in translation? (1 point)
O To unzip the DNA strand for transcription
• To match the base pairs from mRNA to the new DNA strand
• To carry the mRNA from the nucleus to the cytoplasm
• To read the code in the mRNA and produce a chain of amino acids
5. What is the effect of a mutation in a DNA sequence prior to transcription? (1 point)
• Only a positive effect on the organism
• Only a negative effect on the organism
O A mutation would not affect the organism in any way
• A mutation could have a helpful, harmful, or no effect
O A mutation could have a helpful, harmful, or no effect.
