Weegy: When recombinant DNA is inserted into the genome of a host organism, a transgenic organism is created.
User: 2. In which phase will crossing-over occur?
A. Meiosis II
B. Prophase I
C. Mitosis
D. Metaphase II
Weegy: Crossing-over occurs in Prophase I.
User: 3. In contrast to eukaryotic cells, prokaryotic cells
A. have a cell cycle that includes interphase and mitosis.
B. have to go through prophase, metaphase, anaphase, and telophase.
C. have to use binary fission to divide.
D. have to pass through the G1, S, and G2 phases to prepare for division.
Weegy: In contrast to eukaryotic cells, prokaryotic cells: have to use binary fission to divide.
User: 4. Which of the following accurately pairs the cell part with its function?
A. Nucleus—produces energy
B. Cytoskeleton—moves cells and cell parts
C. Smooth ER—assembles proteins
D. Lysosomes—control the cell's activities
Weegy: Cytoskeleton moves cells and cell parts. This accurately pairs the cell part with its function.
User: 5. Suppose a dominant allele (N) codes for a big nose and a recessive allele (n) codes for a small nose. Imagine that an organism receives a dominant allele from its mom and a dominant allele from its dad. What can be determined about its genotype and phenotype?
A. The organism has a small nose, because it's homozygous.
B. The organism has a small nose, because it's heterozygous.
C. The organism has a large nose, because it's heterozygous.
D. The organism has a large nose, because it's homozygous.
