Answer #1

(1) B.The same amino acid is conserved across the compared proteins

(2) D.The general type of amino acid is conserved across the compared proteins

(3) C.The general property of the amino acid is conserved across the compared proteins.

In multiple sequence alignment of aminoacids asterix or star sign shows the same aminoacid is present in the same position in all the sequence in the querry. While colon sign shows that same type of aminoacids( amnoacids of same size and hydropathy) are conserved. And a period sign shows that same property is conserved.

How do differences in amino acid sequences lead to different protein functions? A. Different amino acids produce different proteins based on the bonds formed between them B. Differences in amino acids lead to the recycling of proteins, which produces other functional proteins. C. Different amino acids cause rearrangements of amino acids to produce a functional protein. D. Differences in the amino acids cause post-translational modification of the protein, which reassembles to produce a functional protein.

1. Error Rate in Protein Synthesis It is often said that protein complexes are made from subunits (that is,individually synthesized proteins) rather than as one long protein because it is more likely to give a correct final structure. a. Assuming an error rate of 1/10,000, what fraction of bacterial ribosomes would be constituted correctly if the proteins were synthesized from one large protein versus assembled from individual proteins? For sake of calculation assume that the ribosome is composed of 50...
