Cold case files recently began re-investigating an old murder case. The murder took place in the park; a young man, James, was h

it
over the head with a brick and killed. Police suspected the jealous former boyfriend of James' wife, Karen. Whoever killed James may
have washed their hands in a near-by bird bath as detectives found blood in the bird bath. Since the murder took place before DNA
fingerprinting was available, the suspected killer, Ronnie, went free. Detectives are now reviewing the blood evidence using DNA
fingerprinting
Based on the DNA fingerprints of all possible suspects, who is James' killer?
A.Aubrey
B.Babs
C.Karen
D.Ronnie

Answer: The killer is C; Karen

Explanation:

After looking at the birdbaths results and Karen's results, you can see that they are the same. This will make Karen the killer. Since the killer washed their hands in the birdbath, the detectives were able to get trace amounts of DNA.

DNA fingerprints are determined by a chemical test. This takes the persons genetic makeup and matches it with other peoples that are in a database. This type of DNA testing can be used in courts, identify bodies, find cures, and also look for missing people.

Match the following. 1. (pl. gametangia) an organ of lower plants, some protists and some fungi, that produces gametes gonad 2.
Dmitry [639]

The correct matching is as follows-

1. (pl. gametangia) an organ of lower plants, some protists and some fungi, that produces gametes- gametangium.

2. the reproductive cell in sexual reproduction- for example, the egg or sperm.

3. gamete-producing organ in animals - gonad.

4. cone-bearing plant - gymnosperm.

5. the condition of having isogametes - isogamy.

Gametangium refers to the specialized organ of algae, fungi, ferns and other plants involved in the production of gametes. A female gametangia is called the archegonia producing the egg cells and the male gametangia is called the antheridia producing the sperm cells.

Sexual reproduction is characterized by the production and fusion of the male and female gametes called the sperm and the egg respectively.

The gamete producing organ in animals is called the gonads. It is the testis in the male and the ovary in the female.

Gymnosperms are naked seeded plants. The scales or leaves modified to form the male and the female cones.

Isogamy is a type of sexual reproduction that involves the gametes of similar morphology with similar size.

What is the new peptide chain when the new dna segment is translated for 3'- TACAGGGTGCTACCCACT-5'
kakasveta [241]

Answer:

Methionine- Serine- Histidine- Aspartate- Glycine- stop

Explanation:

Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.

In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the

mRNA sequence from this DNA during transcription will be:

AUG UCC CAC GAU GGG UGA

From this mRNA sequence, the peptide chain that will result following translation is:

Methionine- Serine- Histidine- Aspartate- Glycine- stop

Write a journal about Jamestown by describing the dangers, the mistakes they did and lastly the hardships? If u do this I will g
Vera_Pavlovna [14]

Answer:

2c. Jamestown Settlement and the "Starving Time"

Explanation:

The first joint-stock company to launch a lasting venture to the New World was the VIRGINIA COMPANY OF LONDON. The investors had one goal in mind: gold. They hoped to repeat the success of Spaniards who found gold in South America.

In 1607, 144 English men and boys established the JAMESTOWN colony, named after King James I.

The colonists were told that if they did not generate any wealth, financial support for their efforts would end. Many of the men spent their days vainly searching for gold.

As a consequence, the colonists spent little time farming. Food supplies dwindled. MALARIA and the harsh winter besieged the colonists, as well. After the first year, only 38 of the original 144 had survived.
