Concept explainers
A.
To determine: The tRNAs encoded by the three different organelles participate in protein synthesis in the cytosol.
Introduction: Transcription is the first of the overall two protein synthesis steps. During transcription, the information encoded in the DNA is copied to an RNA molecule as one strand of the DNA double helix is used as a template.
B.
To determine: The organelle has the largest proportion of nongenic DNA.
Introduction: The cell organelles are made up of Ribosomes composed of about equal amounts of rRNA that is ribosomal ribonucleic acid, and proteins, with a little proportion of lipids and specific metallic ions.
C.
To determine: The main reason for the difference in size of yeast and human mtDNA.
Introduction: The protein synthesis from amino acid sequences specified by the series of codons in messenger RNA is called translation. The translation is the first stage of protein biosynthesis.

Transcription and Translation Practice: (Video 10-1 and 10-2) A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense DNA strand and label the 5' and 3' ends. B. Use the antisense strand that you create in part A as a template to create the mRNA transcript of the gene and label the 5' and 3' ends. C. Translate the mRNA you produced in part B into the polypeptide sequence making sure to follow all the rules of translation. 5'-AGCATGACTAATAGTTGTTGAGCTGTC-3' (sense strand) 4arrow_forwardWhat is the structure and function of Eukaryotic cells, including their organelles?

Analysis shows that high levels of the primary transcript that codes for this protein are found in tissue from the brain, muscle, liver, and pancreas. However, an antibody that recognizes the C-terminal portion of the protein indicates that the protein is present in brain, muscle, and liver, but not in the pancreas.
