Me plz! 6. if dna is stuck in the nucleus, but proteins are made in the ribosomes (out in the cytoplasm), how do we get the information out of the nucleus? a. messanger rna (mrna) b. enzymes c. transfer rna (trna) d. rna (hrna)11. how do trna molecules know where to go? a. they look at the dna coding b. they complement the mrna strand c. they guess d. they get from the ribosomes 16. true or false: after a protein sequence is made, it needs to fold into the correct shape.18. what is one characteristic that determines how the protein folds? a. the amino acids hydrophobicity b. the dnac. the color of the amino acid d. both hydrophobicity and color 19. if all the amino acids were hydrophobic and you placed them in water, what would happen to the shape of the protein? a. it would squish into a ball (as best as possible) b. it would flatten out c. half would flatten and half would be a ball d. all the above20. what is a mutation? a. when something gets changed, or there is a mistake in the dna sequenceb. when the dna strand accidentally leaves the nucleus c. when the mrna strand doesn’t attach to a ribosome d. no protein forms 21. describe the effects a dna mutation could have on a protein. a. the mutation might code for a different amino acid b. it a letter is deleted it could shift the reading frame and change all the subsequent amino acids c. a hydrophobic amino acid could change to a hydrophilic amino acid which would cause the protein to fold differently. d. all the above

Which supports the idea that birds and butterflies both have wings but they do not have a common ancestor with wings? the wings are analogous structures that evolved differently and do not have a similar internal structure. the wings are homologous structures that evolved differently and do not have a similar internal structure. wings of birds are vestigial structures, but the wing structures of bats are not vestigial. wings of bats are vestigial structures, but the wing structures of birds are not vestigial.
