TAMU bio 111 lab exam 2 review (2023/2024) already passed What is the difference between the coding and non-coding region? Coding region: comprised of genes that encode proteins (instructions that determine traits) and makes up 1-2% of human DNA. • Noncoding region: makes up 98-99% of human DNA, contains STRs and is responsible for regulatory functions such as gene transcription. 
What are STRs? Short-tandem repeats (STRs) are unique repeating patterns of the same nucleotide sequence. They can...

from the objective lens. It increases numerical aperture and maintains a uniform light speed. 
increase the resolving power of a microscope. Prevents refraction of light. 
What parts of the microscope does light travel through? Illuminator-The light source for 
the microscope.Diaphragm-Controls the amount of light entering the condenser. Condenser 
lens-Focuses light through the specimen.
