In the process of transcription, the promoter site is


Product Description

1. In the process of transcription, the promoter site is

1. where the repressor molecule binds

2. where DNA polymerase binds

3. where RNA polymerase binds

4. where the operator molecule binds 1. Alleles are

1. sometimes referred to as genotypes

2. can either be dominant or recessive

3. different molecular forms of the same gene

4. all of the above 1. In DNA replication, the following are/is involved

1. DNA ligase

2. DNA polymerase

3. Okazaki fragments

4. All of the above 1. After mitosis, the chromosome number of a daughter cell is

1. doubled compared to the parent cell.

2. Rearranged compared to the parent cell

3. The same as the parent cell

4. One-half as the parent cell 1. Meiosis is a division mechanism that produces 1. two cells

2. two nuclei

3. eight cells

4. four cells 1. Oncogenes are

1. programmed cell death

2. operons

3. mutations in a checkpoint gene and can induce cancer cells

4. inactivated X chromosomes 7. The codon for methionine (Met) is AUG. The anticodon in the tRNA is

8. AUG

9. CAT

10. UAC

11. CAU 1. Crossing over and genetic recombination

1. Maintain the status quo of the genotypes

2. Between homologous chromosomes results in a potentially adaptive variations in traits

among a population

3. Do not affect linkage groups 4. None of the above 1. Karyotyping

1. involves isolating chromosomes arrested in metaphase

2. can be used to compare an individual’s chromosome number to a standardize


3. is used to identify particular chromosomal abnormalities

4. all of the above 1. The dogma of molecular biology is

1. Protein-DNA-RNA

2. RNA-DNA-Protein

3. DNA-RNA-Protein

4. DNA-Protein-RNA

5. all of the above-order does not matter Short answer (4 pts each): 1. What is the major difference between the lytic and lysogenic cycle in regard to bacteriophage

infection against bacteria? 1. Describe the similarities and differences between mitosis and meiosis. Fill in the blanks (1 pt each): Use the word bank provided. mRNA is used in a process called ____________________ to put amino acids in __________________
