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

Reptile [31]

Answer:

a. Determine the allele frequencies of:

f(T) = 0.485 ≅ 0.48

f(t) = 0.515 ≅ 0.52

b. Determine the genotype frequencies of the exposed generation

F (TT) = 0.21
F (Tt) = 0.55
F (tt) = 0.24

the genotype frequencies of the next generation

F(TT) = 0.23
F(Tt) = 0.5

Which processes are involved in the chloroplast of a plant cell?

Ahat [919]

Answer:

Chloroplast absorbs sunlight and it is used to make feed for the plant together with water and carbon dioxide gas. Chloroplasts are used to generate the free energy stored in ATP and NADPH via a photosynthesis process.

Explanation:

The site of photosynthesis action is chloroplast within a plant cell consisting of two chlorophyll molecules (PS1 and PS2), which have been embedded in the thylakoid membranes. The chloroplast consists of two chlorophyll molecules (photosynthetic pigments responsible for the green color of chloroplast). Each chlorophyll molecule absorbs light, caused to depart the chlorophyll molecules. This absorbs two electrons from each phenotype. PS2 electrons pass through the transportation chain for electron carriers, a series of redox reactions that release the energy used to synthesize ATP via Photophosphorylation/Chemiosmose (as the H+ ions diffuse through the stalked particles ATP, which changes the shape and catalysts, the electrochemical gradient diffuses down through the stalky particle ATP synthase).

Then these electrons replace the electrons lost in PS1. PS2 electron is replaced by photolysis electron, which when light strikes chloroplast, splitting the water into oxygen gas, H+ ions, and electron enzymes in the thylakoid space are catalyzed. The PS1 electrons combine to create NADPH with H+ ions and NADP (reduced NADP). These are the light-dependent photosynthetic reactions in chloroplasts. In the light-independent reactions, the NADPH and ATP are created. A pile of thylakoids is known as granum.

The light-independent processes take happen in the stroma. This is the site of carbon fixation; CO2 reacts with RUBP to generate GP (glycerate-3-phosphate) which is catalyzed by the enzyme RUBISCO (the most abundant enzyme in the world) (the most abundant enzyme in the world). The NADPH and ATP from the light-dependent processes convert GP to GALP (glyceraldehyde 3-phosphate). Two out of every 12 GALP molecules produced are used to synthesize glucose that can be employed either in breathing or in cellulose-forming condensation polymerization to add extra strength to the planted cell wall. The other GALP molecules are returned to RUBP.
