SFSU Biology 230 Exam Questions with Answers What are the relationships among genomes, chromosomes, genes, alleles, proteins, traits, and mutations? - Answer-Genomes are chromosomes that are in gametes. Alleles are different versions of the same gene. Proteins directly impact traits. A mutation is an allele and something could be different about the protein. What are the similarities and differences in what DNA, RNA, and proteins are made of? - Answer-DNA, RNA, and proteins are made of mac...
