1 biology N + Reproductive system Name: ate: 1. One reason for Mendel s success with genetic studies of garden peas was that he 4. Which nitrogenous base is normally present in N but absent from RN?. used only hybrid pea plants. used peas with large chromosomes. adenine. cytosine. thymine. guanine. studied large numbers of offspring. discovered the sources of variations in peas 5. ll the heritable genes found in a population constitute the population s 2. strand of N consists of thousands of smaller, repeating units known as. lipids. amino acids. nucleotides. polysaccarides. recessive alleles. chromosome mutations. homologous structures. gene pool 3.

Which two bases are present in equal amounts in a double-stranded N molecule?. cytosine and thymine. adenine and thymine. adenine and uracil. cytosine and uracil page 1

2 7. One difference between budding and binary fission in unicellular organisms is that in budding the 11. ouble-stranded chromosomes are produced as a direct result of the. genetic material is unequally divided. genetic material is equally divided. cytoplasm is unequally divided. cytoplasm is equally divided. synapsis of homologous chromosomes. formation of spindle fibers. replication of chromosomes. formation of cell plates 8. ll nucleotides of N and RN contain a. uracil base. thymine base. ribose sugar. phosphate group 12. gene mutation is believed to involve. replacing deoxyribose with glucose. the substitution of a nitrogen base. hydrolysis of strong hydrogen bonds. replacing a phosphate with a nitrate 9.
