I- Choose the best answer Which of the following statements about the structure and packaging of chromosomal DNA is true? a) Histones are basic proteins that makeup about half the mass of chromatin. b) Histones grip the DNA double helix like a fist, with the DNA in the center. c) Formation of the nucleosome structure is the only condensing step in chromosomal DNA. d) All of the above II- True or False The amino acid sequences of histones vary widely...
Which of the following statements about competition is true? Competitors can coexist by developing ways to benefit the other species. The principle of competitive exclusion allows species with the same niche to coexist. Competition never leads to the complete exclusion of one species. When two competitors have slightly different fundamental niches, the poorer competitor can take refuge in areas that are beyond the better competitor's tolerance.
Identify which statements about denaturation are true and which are false. True statements False statements Answer Bank A denatured protein has a different primary structure than its native state. Cooking an egg hydrolyzes its albumin. Denaturation and digestion refer to the same process. Digestive enzymes hydrolyze proteins. Soaking fish in lime juice (PH 2.3) denatures the proteins, A denatured protein has a different tertiary structure than its native state, Egg white meringue, made by beating egg whites, contains denatured proteins

B) Pseudogenes in different species share the same mutations that made them dysfunctional because of chance. C) Mutations in pseudogenes (except in cases when they restore function) have no real effect on fitness. D) Pseudogenes are RNA models of real genes.

Which of the statements about peptide bonds are true? D A tripeptide contains three amino acid residues. Peptide bonds are ester linkages. Peptide bond formation is a hydrolysis reaction. O Peptides are polymers of amino acids. Peptide bonds form from nucleophilic attack by an a-carboxyl carbon atom on an electron pair of an a-amino nitrogen atom of another amino acid.
