Indicate the correct designation of the paired sex chromosomes.

Stem cells are cells that can differentiate into many different kinds of cells. Scientists have discovered that the environment

expeople1 [14]

When stem cells grown on hard, rigid surface, then they became bone cells. Researchers demonstrate in Nature materials that human mesenchymal stem cells grown on a rigid substrate for some time become biased toward differentiating into bone-cell lineage, whereas cell grown on softer surfaces are just likely to eventually follow a bone or fat cell fate.

Suppose that the plasma membrane around a eukaryotic flagellum is opened to reveal the axoneme inside. the radial spokes connect

mash [69]

The flagella of the eukaryotes is composed of the doublet microtubules. The central bundle of these microtubules is known as the anoxeme. In an axoneme, a single pair of the singlet micortubules is surrounded by the nine doublet microtubules. When the plasma membrane of the flagellum is opened to expose the axoneme, and the radial spokes are broken, it will lead to the elongation of the axoneme,

1. In addition to mechanical and chemical digestion of food, the stomach's other major function is: carbohydrate and nucleic aci

Alenkasestr [34]

Answer: Food storage

Explanation:

Stomach is a small pouch like structure which has the ability to store food temporarily.The storage of the food temporarily takes place in the stomach. The food that we eat reaches to the stomach by the help of food pipe.

Here, the food is stored until it is completely broken down into simpler form and enzymes act on them.

The food is then absorbed in the small intestine. But before this food is temporarily stored in the stomach where all the digestive juices and enzymes come to act on the food.

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
