Pre-Lab Questions 1. What are chromosomes made of? Chromosomes are structures composed of DNA and proteins known as chromatin. Within chromatin, there is a component called a nucleosome. 2. Compare and contrast mitosis and meiosis. Both meiosis and mitosis start with only two chromosomes and involve the creation of new cells. However, meiosis does not involve crossing over and synapsis, whereas mitosis, which occurs in somatic cells, does. Mitosis produces body cells, while meiosis produc...

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...
