Answer:
D) It held DNA
Explanation:
The nucleus controls and regulates the activities in a cell. It carries the genes or structures that contain the hereditary information. (DNA)
Answer:
through lysogenic cycle
Explanation:
The bacteriophage attaches itself on the bacterial surface. The DNA strand to be replicated is injected into the bacteria by the bacteriophage. The DNA integrates into the bacterial chromosome and becomes a pro-phage.
The bacterial cell proceeds to cell division through budding. The progeny possess the bacteriophage. After complete replication, the virus DNA detaches from the host genome and enters the lytic cycle. The capsid heads assemble on the surface of bacterial cell to package the fully matured viral DNA . The phage produces lytic enzymes that weaken the cell wall of bacteria cell.
Answer:
E
Explanation
The structure of saturated fats are not flexible unlike unsaturated fats. ALso in the diagram, there are no double bonds which are present in unsaturated lipids, eliminating A and B. Triglycerides have 3 fatty acids shown with 3 carbons that are connected with long bonds unlike phospholipids that has 2 fatty acids. Therefore the answer is E.
Parental Phenotypes: "Yellow-Smooth", "Yellow-Wrinkled", "Green-Smooth", "Green Wrinkled".
Parental Genotypes: SsGg × SsGg
Parental Gametes: SG, Sg, sG, sg
<span>
Smooth/Green </span>= S-G- = 9
<span>
Winkled/Green </span>= ssG- = 3
Smooth/Yellow = S-gg = 3
Wrinkled/Yellow = ssgg = 1
Ratio would be: 9: 3: 3: 1
Hope this helps!
Answer:
Few crosses
The complexity of cat genetics
Crosses not controlled by the researcher
Explanation:
The purpose of this question is to determine why Megor Grendel is less famous than that of Gregor Mendel.
Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:
- The researcher has total control over the crosses.
- Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
- Pea plants may be examined for a greater series of generations than cats or other animals.
- Because plant genetics is not overly complicated, several traits may be investigated at the same period.
As a result, the primary factors why Megor Grendel's experiments are not well-known:
- The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
- Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
- Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.
As a result, it is impossible to draw any conclusions from them.
