Question

s3. Protein structures have several different levels of organization. The primary structure of a sequence. The secondary and tertiary structures are more complicated. Consider the deftinitions that best fits the term protein domain. A) a small cluster of a helices and sheets B) the tertiary structure of a substrate-binding pocket C) a complex of more than one polypeptide chain D) a protein segment that folds independently protein is its amino acid below and select the one 54. For each of the following sentences, fill in with the best word or phrase selected from the list below. Not all words or phrases will be used; each word or phrase should be used only once The a helices and sheets are examples of proter, is composed of more than one protein sequence is known as its structure. A protein such as hemoglobin, which structure. A protein's amino acid has ,, is the modular unit from which structure. A protein many larger single-chain proteins are constructed.

Explanation / Answer

53) D. Protein segments that fold independently

54) The alpha helix and beta sheets are examples of protein secondary structure. A protein such as hemoglobin which is composed of more than one protein subunit has quaternary structure. A protein's amino acid sequence is known as primary structure. A protein domain is a modular unit from which many larger single chain proteins are constructed. The 3 dimensional conformation of protein is its tertiary structure.

55) 1) Replication

2) Transcription

3) Reverse transcription

4) RNA

5) Translation

Viruses are non cellular and are considered as non living because it cannot self reproduce outside the host cell. It becomes living and can reproduce within the host cell.

4) Set of all nucleotide sequences in an organism is called genome-TRUE

Human genome includes chromosome and mitochondrial DNA- TRUE

Bacteria are eukaryotic organisms-FALSE

Living organisms classified in 3 domains-TRUE

Microscopic algae and fungi are prokaryotes-FALSE
