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...

What are the events that take place in a sexual cycle and why is this cycle significant? Ans: -Gamete formation (1n Haploid) -Fertilization (Syngamy) of gametes. -Zygote formation. Zygote is first 2n (Diploid) cell. Then recombination occurs (Basically, Haploid cells (Gamete and spirm) form to create Diploid cell (Zygote)) What is the first supergroup? Ans: Excavata What is asexual reproduction? Ans: One parent, and offsprings are identical clones to parent. What are the 3 organisms of...
