What information did you include in our<br> response?
Daniel [21]

Answer:

All of the statements are true.

The X chromosome is one of the two sex chromosomes of humans and some animals (the other sex chromosome is the Y chromosome). Men have a single X chromosome and women two X chromosomes.

Diseases whose gene is localized on the X chromosome are most often transmitted in the X-linked recessive mode; some are transmitted on the dominant mode related to the X.

In this mode of inheritance, the morbid allele behaves like a recessive trait.

Women heterozygotes are not affected but can transmit the disease; they are aid to be conductive of the disease.

The disese is only manifested in male subjects (XY) with only one copy of the gene (hemizygous subjects)

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
