QUESTION 1 (5 marks) A molecule of messenger RNA (mRNA) has just been synthesized and processed in the nucleus of human cell wit
Dmitry [639]

1) DNA Template strand: TACAATCGACCCATC. 2) Anticodon: AAU. 3) mRNA carries genetic information to build the protein. 4) 5 amino acids. 5) Amino acids: Met, Leu, Ala, Gly, Tyr.

1)

<h3>What is the template strand?</h3>

When the DNI molecule separates into two strands to form the transcription bubble, we can identify two separate segments:

  • The coding strand that goes in 5' to 3' direction
  • The complementary strand -template strand- that grows in 3' to 5' direction .

The template strand is the one that is going to be complemented by the mRNA.

mRNA ⇒ AUGUUAGCUGGGUAG

  DNA ⇒ TACAATCGACCCATC

Remember that pairs are as follows

<u>DNA    RNA</u>

T     →    A

A     →    U

G     →    C

<u>C     →    G   </u>

2)

<h3>What is an anticodon?</h3>

The anticodon is the sequence of three nucleotides that couples with the mRNA codon.

Each tRNA has two important sites. One of them is the anticodon that couples with the codon of the mRNA molecule. The other one carries the amino acid that is going to be addeded to the protein.

                              1st      2nd     3th     4th   5th

mRNA codons ⇒ AUG   UUA   GCU  GGG  UAG

tRNA anticodon ⇒         AAU

3)

<h3>What is translation?</h3>

Translation is the stage of protein synthesis during which mRNA carries genetic information needed to synthesize the new protein in the cytoplasm.

Steps,

1- The formed mRNA moves to the cytoplasm through the nucleus membrane pores.

2- Once in the cytoplasm, mRNA meets a ribosome, the primary structure for protein synthesis.

3- Ribosomes are organelles composed of the association of proteins with rRNA and tRNA. They can be found in the rough endoplasmic reticulum or floating in the cytosol.

4- While the ribosome reads mRNA strain from its 5' extreme to 3', tRNA adds the correct amino acids to build the polypeptide.

The function of mRNA during translation is to take genetic information needed to build the protein.

4)

<h3>How many amino acids are determined per codon?</h3>

Each codon codes for only one amino acid.

There are cases in which different codons code for the same amino acid, but a single codon always codes for one amino acid.

mRNA codons ⇒ AUG   UUA   GCU  GGG  UAG

Amino acids     ⇒ Met    Leu     Ala     Gly    Tyr

                                 1        2         3        4        5

This mRNA segment represents 5 amino acids.

5)

Amino acids     ⇒ Met    Leu     Ala     Gly    Tyr

Which is a limitation of a scientific model?
iren [92.7K]

Answer:

The correct option is<em> D)  Models are not the "real thing" so it will never correctly represent the system in all respects.</em>

Explanation:

Scientific modelling can be described as a representation of the scientific theories or concepts in a way that can be better understood. Scientific models makes it easier to understand what physical, chemical or mechanical activity is taking place. Even mathematical representation comes under scientific modelling.

As models are not the real, hence they cannot be considered to be perfectly accurate. A model can never mark up to the complexity of nature.

The map shows the main streams and the rivers near City A and City B, as well as the nearby factories and farmland. The arrows i
AveGali [126]

Answer:

A. City A because there are no pollution sources upstream.

Explanation:

Water pollution is th contamination of water. There are many means through which water is contaminated such as industrial waste, agricultural waste and domestic waste et-cetra.

City A and City B get water from sunset lake and moth lake which have factories (industrial waste) and farmland (agricultural waste) nearby them, which are responsible for the contamination of river water. due to this cities can recieve contaminated water which can affect their health.

But the quality of water in City A will be best than that of City B because according to the image, City A do not have nay upstream soooooource of pollution, as factories and farmland are located at downstream.

Hence, the correct option is A.
