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...

Biology 1000 – Principles of Biology ( BioS 115 Core II: Genetics) Exam Study Guide Questions With Answers. Explain the concepts of penetrance and expressivity Penetrance is the percentage of cases in which a certain phenotype is expressed. There are two types: i. Complete Penetrance: when 100% is correlated to the genotype. So, all express the same thing. ii. Incomplete: this is when some are identical, and others are different. Penetrance= # with genotype showing phenotype x 100 # wit...
