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...

PENN FOSTER BIOLOGY: Genetics and Inheritance Questions and Answers Already Passed What is the basic unit of heredity? The gene What is the principle of segregation in genetics? Each individual has two alleles for each gene, which separate during gamete formation so each gamete carries only one allele. What does a Punnett square illustrate? The possible genetic combinations resulting from a cross between two parents. What is the difference between homozygous and heterozygo...

Bio 189 Midterm Study Guide Questions and Answers Rated A+ What role do telomeres play in cellular aging? Telomeres protect the ends of chromosomes from deterioration or fusion with neighboring chromosomes, and their shortening during cell division is associated with cellular aging and limit the number of times a cell can divide. Describe how the structure of the phospholipid bilayer contributes to its function. The phospholipid bilayer's hydrophilic (water-attracting) heads face...

CBE 235 FinalLac Operon - correct answer -involved in heating lactose: inducible operon 1) The lactose repressor protein coded by Lacl bound to the operator tightly near the mRNA start site, blocking the ability of RNA poly to bind 2) Lactose introduced--> Lac repressor binds to lactose and changes conformation such that it can no longer bond to the operator 3) RNA poly can access the promoter and transcription goes 4) LacZ,LacY,LacA are transcribed Gregor Mendel Experiment - correct a...

LIFESCI 2G03 Test 1 Questions and Answers Already Passed Question: What is the main function of enzymes in biological systems? Answer: Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required for the reaction to proceed. Question: How does the structure of DNA enable it to carry genetic information? Answer: DNA's double-helix structure, composed of nucleotide pairs (adenine with thymine and cytosine with guanine), allows it to store and...
