2. What process do mRNA and tRNA work together to complete? (3 points)
liberstina [14]

Answer:

Translation

Explanation:

This process occurs in the ribosomes. As the ribosome reads the codons on the mRNA the corresponding tRNA with the complementary anticodon is recruited. The tRNA brings in an amino acid (attached to it), and the amino acid is joined to the rest of the growing  polypeptide chain. Each codon/anticodon specifies for a specific amino acid.

Draw a DNA molecule that has five randomly spaced restriction sites for a spedific palindrome. How many fragments would be produ
Bond [772]

Answer:

Figures attatched

Explanation:

1. Restriction enzymes cut the DNA in specific places of a specific sequence. Each restriction enzyme has different sequences of recognition.

2. Palindromic sequences are sequences that can be read the same in both senses (3' and 5'), for that reason restriction enzymes can cut both DNA strands

Now, for the first image: if a molecule has 5 restriction sites that are known for a single restriction enzyme, the enzyme will cut the DNA 5 times. If you see the image, the number of fragments is the number of restriction sites +1. In this case, it is 5+1=6 DNA fragments.

In the case of two different palindromic sequences, two different restriction enzymes recognize different sequence. If just one enzyme is present, the only cutting site will be the one that has the palindromic sequence recognizable. So, the number of fragments will be 1+1=2 DNA fragments (figure 2)

Which of the following promotes closure of the minivalves associated with lymph capillaries?
Molodets [167]

Answer:

increasing pressure inside the lymph capillary

Explanation:

Lymph is a fluid like the blood which carry the White blood cells which can fight against the infection. The lymph flows in separate vessels called lymphatic vessels.

The lymphatic vessel is very thin-walled smooth muscle containing tube-like structure which allows the transport of lymph.

The lymph vessel like blood vessel contains the valves called mini valves which prevent the backward flow of the lymph.

When the pressure in the tiny lymph capillaries which supplies lymph to the organs increases, the mini valves closes to prevent backflow of lymph and is the mechanism of lymph flow.

Thus, the selected option is the correct answer.
