SFSU Bio 230 Study Guides for Exams 1, 2, 3, and 4 Questions and Answers Grade A+ How are chromosomes, genes, alleles, proteins, traits and mutations related? - ️️ Chromosomes contain DNA which contains genes that can vary and are then called alleles, which code for proteins that can be expressed as traits. Mutations happen. What causes cancer?Are all mutations caused by mutagens? - ️️ Cancer can be caused by inheritance or sporadic mutations (mutagens). Not all mutations are cause...

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...

Blending Inheritance Theory - ANSWER-Theory that the traits of parents were blended together to result in an equal distribution of traits in their offspring Mendel's First Theory - ANSWER-The principle of segregation (First Law): The two members of a gene pair (alleles) segregate (separate) from each other in the formation of gametes Factors - ANSWER-Genes, separated during gametogenesis Allele - ANSWER-An alternative form of a gene. Genotype - ANSWER-An organism's genetic makeup, ...
