ipn [44]

Answer:

3 nucleotides in an RNA molecule.

Explanation:

Protein synthesis in the cell produced by RIBOSOMES requires a lot of energy and it's has the highest mass in living organisms. Protein synthesis involve the process where Messenger RNA (MRNA) message is converted to a polypeptide product. The transcription in the cell produced messenger RNA. The translation of mRNA template converts nucleotide-based genetic information into a protein product. The protein sequences contain about 20 Ami o acids and each amino acids is defined by three nucleotides sequence which is called triplet codon. The relationship between nucleotides codon And amino acids is called genetic code

An enhancer may increase the frequency of transcription initiation for its associated gene when… (indicate true or false for eac
Olenka [21]

Answer:

it is located 1000 nucleotides upstream of the gene’s core promoter - true

it is located 1000 nucleotides downstream of the gene’s core promoter- true

it is in the gene’s coding region - False

Explanation:

These enhancers are located 50 or more kilobases from the promoter they controlled upstream from a promoter, downstream from a promoter within an intron, or even downstream from the <u>final exon</u> of a gene which can be thousands of bp away from the gene's core promoter and can also occur thousands of nucleotides away from the gene's core promoter needing the activity of a DNA -bending protein that binds to the enhancer changing the shape of the DNA and allow interactions between the activators and transcription factors.

Describe in words what occurs during the process represented by the photosynthesis equation. Include the importance of sunlight
8_murik_8 [283]

Photosynthesis usually takes place in the leaves. Leaf cells contain many chloroplasts (up to 50 per cell). These organelles contain a green pigment, chlorophyll, capable of capturing light energy. This energy is used to make sugar molecules from water drawn from the soil by the roots and carbon dioxide from the atmosphere, captured by the leaves. The sugars produced subsequently distributed in the different parts of the plant.

Here is the reaction of photosynthesis:

6 CO2 + 6 H2O + light energy ==> C6H12O6 (glucose) + 6 O2

But this balance is in fact broken down into two successive stages:

photochemical reactions (clear phase):

12 H2O + light ==> 6 O2 + chemical energy;

the Calvin cycle (dark phase):

6 CO2 + chemical energy ==> C6H12O6 + 6 H2O.

The first phase of photosynthesis, called clear phase, requires the illumination of the leaf. Chlorophyll, which is embedded in the thylakoid membrane, absorbs light energy. This energy absorption is accompanied by the degradation of water molecules and the release of oxygen.

In a second phase independent of light, called the dark phase, the energy absorbed by chlorophyll is used for the transformation of carbon dioxide molecules into sugar molecules.

The sugars made by photosynthesis are stored in the cell as starch, transformed into other organic molecules, such as proteins, or degraded in the mitochondria during respiration to meet the energy needs of the plant.

Asbestos breaks down into small fibers. What may result if these fibers are inhaled?
jeka57 [31]
When they are breathed in, they can become trapped in the lungs and stay there for many years. Many problems might result in accumulation of such. One would be asbestosis, an inflammatory condition of lungs that can cause shortness of breath. Another would be mesothelioma, a rare cancer that affects the lining of the lungs, chest cavity, or abdomen.
