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...

transduction Correct Answer The mechanism of DNA transfer in bacteria where DNA is transferred by phages (bacterial virus) nicks at specific origin, outer strand peels off and goes through pillis to F- cell while being resynthesized in F+ Correct Answer What is the process of conjugation? F- cells (replicate the F plasmid so the F- cell has one too) Correct Answer For conjugation, what do F+ cells look for? 0.13 to 14 million bp, e coli has 4.6 million bp Correct Answer What is the ...

Bio 115 WVU Final (Dr. Barry) Questions and Answers Graded A+ For e. coli , the lacl repressor gene is expressed when? The lacl repressor gene is always expressed Where does the lacl repressor gene attach The lacl repressor gene codes for a protein which attaches to the lac operon operator In the absence of lactose, does the lacl repressor gene bind to DNA Yes, in the absence of lactose, the lacl repressor gene binds to DNA preventing transcription; this is an example of negative...

What is the cell theory? All organisms are made come from cells and are made up of cells Cells must reproduce for what 2 reasons? Cells must reproduce either to perpetuate the species or create a multi-celled individual Cell reproduction involves which two processes? Cell reproduction involves mitosis (duplication and division of the nucleus) and cytokinesis (division of the rest of the cell) If the process of cell reproduction via mitosis & cytokinesis produces identical (clone) cells, the...
