Question

2. Mitosis results in two daughter cells. When comparing the genetic information of the parent cell with that of the two daughter cells,

1. all three are identical.
2. the two daughter cells are identical but slightly different from the parent cell.
3. all three are slightly different.
4. the parent cell and one daughter cell are identical, while the second daughter cell is slightly different.
5. outcome patterns vary.

3. What purpose do restriction enzymes play in bacterial cells?

1. They prevent the overproduction of mRNA in the bacterial cell.
2. They attack bacteriophage DNA when it enters the cell.
3. They promote bonding of the RNA polymerase to the promoter.
4. They limit the rate of bacterial replication.
5. They connect Okazaki fragments.

4. One of the mRNA codons specifying the amino acid leucine is

1. 5’–GAT–3’.
2. 3’–AUC–5’.
3. 3’–GAU–5’.
4. 3’–GAT–5’.
5. 5’–GAU–3’.

5. An operon is

1. a repressor that binds to a promoter.
2. a molecule that switches a gene off or on.
3. a gene that cannot be repressed or enhanced.
4. a functional unit of promoter, operator, and structural genes in bacteria.
5. none of the above

Answer 1

Option that are cells Mitosis produce a daughtee parent occue no identical to crossing over in Option 13 The restoriction enzymes bacteria have protective the DNA of bacteriophases and bacterial cell. vole, they attack pestent Codon Anticodon 3 30 - GAU-51 Option c A 11111 2 J G C — А. G Codon strand it opposite to anticodon strand. Option E E- None 4 DNA An functional unit of that opevon is include and stenctural CS Scanned with CamScanner Ope vratae genes.
