A cellular biologist is curious as to why a protein is not being expressed even though they placed the needed transcription factors and ribosomes allowing for the transcription and translation of the protein to take place in the cell. They look at the mRNA and find it is being translated and exported to the nucleus but ribosomes are not binding to it. After careful observation she finds out that the mRNA is missing its _____________. Without this of course ribosomes would have an issue binding to the mRNA and inducing translation.

Answers

Answer 1

Answer:

5' cap

Explanation:

In eukaryotes, the 5′ end of mRNA in eukaryotes is modified (i.e., capped) with a guanine nucleotide which is connected to mRNA via 5´→ 5´ triphosphate linkage. The five-prime cap (5′ cap) is denoted as 7-methylguanylate cap (m7G) because guanosine is methylated at the 7 position by a 7-methyl transferase. This cap acts to protect the mRNA from degradation and also is required during translation initiation in order to mediate a process known as ribosome recruitment. This process (ribosome recruitment) occurs through the association of the 43S preinitiation complex (composed of the small ribosomal subunit, eIF1, eIF1A, eIF2, eIF3 and eIF5 factors) with the 5' capped mRNA. After mRNA binding, the 43S preinitiation complex is ready to scan an initiation codon in order to start the translation.

Why is it bad when extra nitrogen leaves the soil?

Answers

Excess nitrogen can also leach or drain from the soil into underground water sources, or it can enter aquatic systems as above ground runoff. This excess nitrogen can build up, leading to a process called eutrophication.

Answer:

When plants lack nitrogen, they become yellowed, with stunted growth, and produce smaller fruits and flowers. Not enough nitrogen in the soils leaves plants hungry

2. Producers are living things that use energy to make food. Producers make food for themselves and other living things.

3. the difference between a herbivore and an omnivore is a herbivore eats only plants or producers, and an omnivore eats both plants, and other animals/consumers.

what forms after the glycosidic linkage reaction between glucose and galactose is complete

Answers

What forms after the glycosidic linkage reaction between glucose and galactose is complete would be lactose.

Glucose and galactose are known as simple sugars or monosaccharides. Monosaccharides can combine together to form disaccharides or even polysaccharides.The combination of monosaccharides to form di or polysaccharides happens by a process known as condensation reaction.The condensation reaction results in the formation of glycosidic linkage or bond and elimination of water moleculesGlycosidic bond is a type of covalent bond th joins one sugar molecule to another sugar or non sugar molecule.

Thus, lactose is a dissacharide consisting of one glucose and one galactose unit which combine together by condensation and formation of glycosidic bond with elimination of water.

Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.

What is protein?

Proteins are among the most prevalent organic molecules in biological systems and have a much wider range of structural and functional variations. Many thousands of proteins, each serving a different purpose, can be found in a single cell.

All proteins are composed of one or more chains of amino acids, despite the fact that their structures and activities differ substantially from one another.

In biological reactions, enzymes function as catalysts, accelerating the reactions. Each enzyme may distinguish between one or more substrates, or the molecules that act as the catalysts for the reactions they catalyze.

Therefore, Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.

Known as the 'Pine Tree State; Maine's state tree is the Eastern white pine. Consider the model. Cärbon dioxide, water, and sunlight
are reactants of photosynthesis and are used to produce glucose and release water as a byproduct. What advantage does the pine tree
have in performing photosynthesis compared to deciduous trees such as oak or maple?
34)
A) Pine trees need less water to do photosynthesis.
B) Pine trees produce twice as much glucose as deciduous trees.
C) Pine trees do not lose their leaves and can photosynthesize all year.
D) Pine trees get more sunlight than oak trees due to their darker color.

Answers

Answer:

C) Pine trees do not lose their leaves and can photosynthesize all year.

Explanation:

In cold-temperate and Arctic regions, however, evergreens are typically cone-bearing shrubs or trees (conifers), such as pines and firs. Many tropical species of broad-leaved blooming plants are evergreen. Thus, option C is correct.

What are features of pine trees?

Pine trees may photosynthesize in the winter because they retain their needles all year long! Compared to trees that lose their leaves, this is a significant advantage.

Their leaves therefore stay green and stay attached for a longer period of time than their deciduous counterparts because they can preserve more water.

However, because of their tiny surface area, needles are not as effective at absorbing the sun's energy.

Therefore, Pine trees do not lose their leaves and can photosynthesize all year.
