What is the main difference between protein domains and protein subunits? Group of answer choices1. Protein domains do not have secondary structure, whereas protein subunits always have secondary structures 2. Each subunit represents a separate polypeptide chain, while one polypeptide chain may contain several domains 3. Domains are parts of membrane proteins, while subunits are parts of water-soluble proteins 4. Domains are composed mostly of the alpha-helices, while subunits contain both alpha-helices and beta-strands 5. The tertiary structure of domains is stabilized by hydrogen bonds, while the structure of subunits is stabilized by disulfide bonds

This problem has been solved! see the answeryou are investigating two traits in fruit flies controlled by one gene each. the b gene controls for body color (black or brown), while the r gene controls for body sculpture (rugose or smooth). after crossing rugose black flies with smooth brown flies, you obtain an f1 generation of 100% smooth black flies.what are the dominant alleles? (1 pt)what are the genotypes of the two parent flies to perform a dihybrid test cross? (1 pt)after running a dihybrid test cross, you find 1000 offspring with the following phenotypes: , rugose406black, smooth86brown, rugose94brown, smooth4141000fill in the expected column with the expected number of offspring in each class of phenotypes. (1 pt)what phenotype classes represent the recombinant offspring? (1 pt each)calculate the relative genetic distance between the body color gene and the body sculpting gene (show your work). (1 pt).
