Karenca was studying her genetics notes the night before the test. She was getting a little turned around with the differences between DNA and RNA. She started working a problem
that gave a segment of original DNA as follows:
TAA
Then, the problem said that original DNA was mutated to become:
TAG
Use the codon table to help Karenca determine whether or not this mutation will cause a
change in the phenotype (what the organism looks like) of the organism. * mm

1. describe the structure and function of the specialized cells you observed in the video. 2. research the types of cells present in the kidney.

One function of the poly-a tail on eukaryotic mrna sequences is to the mrna be transported from the nucleus to the cytoplasm. prokaryotic mrna also has a poly-a tail. choose the best explanation of the prokaryotic poly-a tail. a. prokaryotic poly-a tails are composed of a different molecular structure compared with eukaryotic poly-a tails. b. prokaryotic poly-a tails have the same functions as eukaryotic poly-a tails, because this process is highly conserved throughout different species. c. prokaryotic poly-a tails aren't important, because prokaryotes don't have nuclei. d. prokaryotic poly-a tails have other functions, because prokaryotes don't have nuclei.

Describe your dna model. which part do the straws represent? the pushpins? the paper clips and the black dots you made with the marker?
