26. Suppose the two guanosine (G) nucleotides in #3 above were changed to two cytosine (C) nucleotides. What is the new amino ac

seropon [69]

Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed question can be found in the attachment below.

During protein synthesis, a sequence of three mRNA nucleotides (called codons) correspond to specific amino acids. From the question, the change in guanosine nucleotides will change the sequence as follow

DNA: T--A--C--A--A--C--T--A--C--T--T--C--T--T--T--C--T--T--A--A--A

mRNA: A--U--G|-U--U--G|-A--U--G|-A--A--G|-A--A--A|-G--A--A|-U--U--U

Amino Acids: met -- leu -- met -- lys -- lys -- Glu -- Phe

The new amino acid sequence is represented above from the new DNA sequence.

Which of the following is an example of post-transcriptional control of gene expression?

konstantin123 [22]

Answer:

Option (c).

Explanation:

Transcription may be defined as the process of formation of RNA molecule from the template DNA with the help of enzymes and transcription factors. The transcription occurs in 5' to 3' direction.

Post trancriptional modification occurs in the RNA molecule that plays an important role in transcription as well as translation. The introns are removed from the RNA transcript and exons joined together is known as splicing. The alternative splicing occurs in which different protein isoforms are formed by the single exons.

Thus, the correct answer is option (c).

How are climate change and global warning related?

s344n2d4d5 [400]

So Global warming is the rise in global temperatures due mainly to the increasing concentrations of greenhouse gases in the atmosphere.

Climate change is the increasing changes in the measures of climate over a long period of time.

This includes : precipitation, temperature, and wind patterns.

Hopes this helps :)

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

T → A

A → U

G → C

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
