The correct option is D.<span>
Craig Venter contributed significantly to
science and humanity by inventing a synthetic cell. He accomplished this by
constructing the genome of a bacterium and by incorporating it into a
cell. The cell was made by joining together the genome of a pathogen from small stretches of DNA that are synthesized in the laboratory. The genome created was then inserted into an empty cytoplasm of a related bacterium. The pathogen use is called mycoplasma mycoides, it usually infect goats.</span>The cell is the first synthetic life form in the world and it open the
way for new types of research.
In Eukaryotes, the DNA replication can start at several sites or places in the DNA molecule or DNA strand. The only important factor for DNA replication to start is that it starts at replication fork.
The replication of DNA is semi-conservative in nature because each strand acts as a template for synthesizing a new complementary strand of the double helix.
The new DNA is made with the help of the enzyme DNA polymerase which requires a primer for starting the DNA synthesis.
Replication occurs only at specific regions of DNA known as origin of replication and these are short sequences of nucleotides which are recognized by the enzyme for the replication.
The special enzymes or proteins recognize the specific sites and then binds to them. After binding, the DNA is opened up forming the replication forks which are two Y- shaped structures.
I think the answer you are looking for is that the stomach is the fourth level of organization.
Increasing predator population
Answer:
The correct answer is explained below:
Explanation:
- According to the question, heterozygous tall, heterozygous axillary plant has the following genotype, TtAa.
- It produces the following gametes: TA, Ta, tA, ta.
- The heterozygous tall, terminal plant has the following genotype: Ttaa
- It produces the following gametes: Ta, ta.
- Crossing them,
TA Ta tA ta
Ta TTAa TTaa TtAa Ttaa
(Tall, Axillary) (Tall, Terminal) (Tall, Axillary) (Tall, Terminal)
ta TtAa Ttaa ttAa ttaa
(Tall, Axillary) (Tall, Terminal) (Short, Axillary) (Short, Terminal)
- The genotypes of the offspring obtained are: TTAa, TTaa, TtAa, Ttaa, ttAa and ttaa respectively.
- The phenotypes obtained are:
- Tall, Axillary = 3.
- Tall, Terminal = 3.
- Short, Axillary = 1.
- Short, Terminal = 1.
