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

Describe competitive and noncompetitive enzyme inhibition?
kozerog [31]

Answer:

use own words

Explanation:

In competitive inhibition, an inhibitor molecule is similar enough to a substrate that it can bind to the enzyme's active site to stop it from binding to the substrate. ... In noncompetitive inhibition, an inhibitor molecule binds to the enzyme at a location other than the active site (an allosteric site)

hat is the difference between competitive and non competitive inhibition?

The main difference is that in competitive inhibition, the inhibitor binds directly to the active site of the enzyme. ... Competitive inhibition can be overcome by increasing the concentration of the substrate. This cannot occur with non-competitive inhibition.

f a rabbit breeder crossed a white rabbit and a black rabbit in a complete dominance pattern, then all of the offspring would be
lilavasa [31]

Answer:

- Complete dominance: one allele masks the expression of the other gene variant or the phenotype is caused by the absence of gene function when both alleles are recessive.

- Incomplete dominance (codominance): both alleles are expressed and contribute to the phenotype

Explanation:

Complete dominance is a type of dominance by which one allele (dominant allele) completely masks the effects of another allele (recessive allele) in heterozygous individuals (i.e., individuals carrying two different gene variants or alleles). On the other hand, codominance refers to a type of incomplete dominance where both alleles in the genotype are observed in the phenotype. Complete dominance is caused when the recessive allele is not expressed, while if both alleles are expressed it is called incomplete dominance.
