Question
Chapter 39.5, Problem 2Q
Summary Introduction
To determine:
The way in which corneas should be reshaped by laser surgery to correct nearsightedness and farsightedness respectively.
Introduction:
An individual can see objects because the light from that object falls on the fovea of the retina. The focusing of light begins at the cornea and ends at the lens. When focusing on nearby objects, this lens becomes rounded; and to focus on distant objects, it becomes flattened.
If an individual cannot see the nearby objects clearly, it means that their cornea is too rounded, due to which, light from nearby objects falls behind the retina. Individuals with this problem are farsighted.
If an individual cannot see the distant objects clearly, it means that their cornea is too flat, due to which, light from nearby objects falls in front of the retina. Individuals with this problem are nearsighted.

Students have asked these similar questions
a) Find a nitrogen base. What carbon is the base attached to?
b) What two nitrogenous bases are held together by 2 hydrogen bonds?
c)What two nitrogenous bases are held together by 3 hydrogen bonds?
You will be building a double-stranded DNA molecule, representing a short (20 base) sequence that could be found in a chromosome. It will have a 3' --> 5' strand and a 5' --> 3' strand.
Use two full 12-base-pair DNA models.
a) Upload a photo of a model once the first 6 nucleotides have been inserted to base pair with the two parent strands.
b)Upload a photo of DNA polymerase I and Ligase in "action" removing the RNA primer nucleotides and making new phosphodiester bonds.
c)Upload a photo of the final two DNA strands, after Termination, identifying the parent and daughter strands of each.
Write down the 12 base-pairs (ex A-T or G-C) contained in the two models you will us from top to bottom below
Model 1 bp:
