Answer:

1) RNA strand = UCA GCA AAU

2) Amino acids: Asparagine Arginine Stop

(ASN) (ARG) (STOP)

Explanation:

Some theory that you need to know to answer the question:

Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA. Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid.

tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.

Once the new amino acid joins the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.

Now, to fill in the boxes, you need to pay attention to two things:

• Anticodon: In this box, you need to place the sequence of bases that pairs with the mRNA codon.

• Amino Acid: In this box, you need to place the amino acid that is codified by the mRNA codon.

For instance, let us say that the codon of mRNA is CUC. The anticodon for this sequence is GAG (because guanine joins cytosine and adenine joins uracyl).

The amino acid places on the 3´extreme of the tRNA molecule will be the one that is codified by the codon, NOT the anticodon. So, as the codon is CUC, the amino acid will be Leucine, Leu. Do not use the anticodon GAG to fill these boxes. Remember that tRNA is translating information carried by the mRNA, so we need to use this information to grow the protein.

Strand of DNI → AGT CGT TTA

Each of these letters are bases → Adenine, A - Guanine, G - Thymine, T - Cytocine, C
Each of these three-lettered groups are codons.

So, we need to pair these bases, knowing that:

Adenine (A) and guanine (G) derive from purines, while Thymine (T) Uracile (U), and Cytosine (C) derive from Pyrimidines.

In the DNA molecule, Adenine (Purine) always pairs with Timine (Pyrimidine), while Guanine (Purin) forms pairs with Cytosine.

In the RNA molecule, Adenine is paired with Uracil, U. So, whenever there is an Adenine in the DNI strand, it pairs with Uracil of RNA strand. If there is a Thymine in the DNI strand, it pairs Adenine of the RNA strand. And, as always, Guanine pairs with Cytosine.

A ⇒ U
T ⇒ A
G ⇔ C

Knowing how to pair bases, we can fill the RNA molecule boxes.

Strand of DNI → AGT CGT TTA
Strand of RNA → UCA GCA AAU

A ⇒ U C ⇒ G T ⇒ A

G ⇒ C G ⇒ C T ⇒ A

T ⇒ A T ⇒ A A ⇒ U

Now we need to translate these new codons of mRNA to amino acids.

To fill the boxes you should have a genetic code chart to see the codons that codify for each amino acid.

Codon: AAU CGA UAG

Amino acids: Asparagine Arginine Stop

(ASN) (ARG) (STOP)

The new protein is synthesized from the amino terminus to the carboxy terminus of the mRNA molecule. The added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches a stop codon, protein synthesis is over.

What is the most accurate classification of the common forms of coronary artery disease and hypertension?

Genrish500 [490]

The most accurate classification of the common forms of coronary artery disease and hypertension is that they are complex disorders which result from gene-environment interactions. For example, almost 60% of CAD cases are found in South East Asia, that too when their population if just 20% of the total world's population. This is due to the environmental interactions with the genetic disposition of the people of this region.

John and Joshua used a light microscope to observe a plant cell. They indicated the magnification as x1000. Given the eye piece

Zinaida [17]

Answer:

Objective Lens Magnification = ×100

Explanation:

In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.

In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.

Total Magnification = (eyepiece lens magnification) × (objective lens magnification)

1000 = 10 × obejcetive lens magnification

Dividing both sides by 10

Objective lens magnification = 1000 ÷ 10 = 10

∴ Objective lens magnification = ×100

What happens to the rate of photosynthesis as the intensity of light or concentration of CO2 increases? And How is your conclusi

NikAS [45]

Answer:

The rate of photosynthesis increases the intensity of light or concentration of CO2 increases, however, at a certain temperature, the rate can decrease due to enzyme denaturation.

Explanation:

Photosynthesis is a unique metabolic process specific to only some organisms. The photosynthetic process, however, cannot occur without some vital ingredients including light, Carbon dioxide (CO2) and optimum temperature.

An increase in the concentration of light (from sun) and CO2 (from atmosphere) increases the rate at which photosynthesis occurs i.e. more light, CO2 results in more photosynthetic process. However, an increase in TEMPERATURE also increases the photosynthetic rate but at a particular temperature, the enzymes that bring about the photosynthetic process can be denatured or damaged, hence, at an EXCESSIVE TEMPERATURE, photosynthesis can be inhibited.
