RNA that, combined with protein into multiple sun bits, constructs a peptide chain must be called what?

A protein had the amino acids leu-gly at codons 10 and 11. A deletion of the 5’ base of the leu codon (i.e. the first base) changed the protein so that it now reads ser-ala at codons 10 and 11. The original Leu codon must have been: (hint: make use of a codon table to answer this question)   CUG AUG CUA CUC      CUU

Describe the helix-turn-helix (HTF) motif?

Rank from left to right the compound with the most reactive chemical linkage: peptide bond, ester, ether, acid anhydride, aminoacyl-TRNA How many bacterial translation factors are "G" proteins? How many proteins are involved in the nucleotide-dependent steps of protein synthesis?

If you want to engineer a cytoplasmic protein to become a peroxisomal protein, which of the following amino acid sequences would you need to add?    A signal sequence to its N-terminus and a KDEL sequence to its C-terminus   An SKL sequence to its C-terminus A signal sequence to its C-terminus and a KDEL sequence to its N-terminus  A signal sequence to its N-terminus and an SKL sequence to its C-terminus  A KDEL sequence to its C-terminus

What general structural feature is shared by proteins that specifically form homodimers (but not homotrimers, homoteramers etc)? Only one answer is correct.     the surface consists of hydrophilic alpha-helix.   the surface is highly modified by post-translational modification.   the surface is permanently bound by chaperones.   the surface is unstructured.   the surface, or part of it, is self-complementary.

3)Which of the following statements are true? Choose all that apply a)There are multiple codons possible for nearly all amino acids b)Each stop codon also codes for an amino acid c)Each tRNA will base pair with only one codon d)The start codon also codes for an amino acid e)Each codon in mRNA codes for exactly one amino acid f)Each codon in tRNA codes for exactly one amino acid g)Each anticodon in tRNA pairs with exactly one codon h)Each tRNA carries exactly one type of amino acid

List the three (3) types of RNA molecules and in one sentence each describe their functions.

What protein structure is represented in either panel of the figure above?   Question 11 options:   a)  Quaternary   b)  Secondary   c)  Tertiary   d)  Quinary   e)  Primary

The human anti-bacterial protein lysozyme, consisting of a single polypeptide with 129 amino acids, contains how many peptide bonds? 131 peptide bonds 130 peptide bonds 129 peptide bonds 128 peptide bonds 127 peptide bonds
