Question

The process called translation results in the production of what? Select one: a. RNA complementary to a template strand of DNA b. A second DNA molecule identical to the parent strand of DNA c. An amino acid chain or protein d. A carbohydrate e. A reindeer The two strands of DNA double helix are antiparallel. What does this mean? Select one: a. The strands run in opposite direction b. The strands run in the same direction c. The bases are on the inside of one strand and on the outside of the other strand d. The sugars and phosphates alternate e. Two purine bases are paired with two pyrimidine bases What biological molecule did most scientists initially believe was the source of hereditary information? Select one: a. Nucleic acids b. Proteins c. Lipids d. Carbohydrates e. Steroids What is the relationship among DNA, a gene, and a chromosome? Select one: a. A chromosome contains hundreds of genes which are composed of protein. b. A chromosome contains hundreds of genes which are composed of DNA. c. A gene contains hundreds of chromosomes which are composed of protein. d. A gene is composed of DNA, but there is no relationship to a chromosome. e. A gene contains hundreds of chromosomes which are composed of DNA. What molecule transports the appropriate amino acid to a ribosome during protein synthesis? Select one: a. DNA b. mRNA c. tRNA d. rRNA e. uRNA

Explanation / Answer

The answers are
11. c. An amino acid or protein

In protein synthesis, there are two steps.
1. Transcription - Synthesis of mRNA from DNA
2. Translation - Synthesis of aminoacids on the basis of mRNA codons

12. a. The strands run in opposite direction.

DNA is composed with two strands. One strand runs with 5' - 3' direction and the other runs with 3' - 5' direction

13. b. Proteins.

This is disproved by Hershey and Chase. They proved that DNA is genetic material by using radio active labelled isotopes.

14. b. A chromosome contains hundreeds of genes which are composed of DNA

15. c. tRNA - transport RNA. On the basis of its transport function of amino acids, the named it as tRNA
