Answers
As DNA is being translated into RNA during gene expression, the non-coding regions are cut out by a procedure known as RNA splicing.
What does place when DNA gets translated into RNA?In the nucleus, transcription occurs. It constructs an RNA molecule from a template made of DNA. Translation takes place when RNA travels from the nucleus to a ribosome in the cytoplasm. A protein is created during translation by reading the genetic code in mRNA.
What happens when you're transcribing?The information contained in a gene's DNA is transferred to RNA (ribonucleic acid), a molecule comparable to DNA, in the cell nucleus during transcription. Both RNA and DNA are composed of a series of units known as nucleotides.

5 functions of mesophyte
Answers
Answer: Find your 5
Explanation:
Mesophytes generally require a more or less continuous water supply. They usually have larger, thinner leaves compared to xerophytes, sometimes with a greater number of stomata on the undersides of leaves. Because of their lack of particular xeromorphic adaptations, when they are exposed to extreme conditions they lose water rapidly, and are not tolerant of drought. Mesophytes are intermediate in water use and needs. These plants are found in average conditions of temperature and moisture and grow in soil that has no water logging. The roots of mesophytes are well developed, branched and provided with a root cap. The shoot system is well organised. The stem is generally aerial, branched, straight, thick and hard. Leaves are thin, broad in middle, dark green and of variable shape and measurement.[citation needed]For example, in hot weather they may overheat and suffer from temperature stress. They have no specific adaptations to overcome this, but, if there is enough water in the soil to allow this, they can increase their rate of transpiration by opening their stomata, thus meaning some heat is removed by the evaporating water. However these plants can only tolerate saturated soil for a certain amount of time without a warm temperature. In dry weather they may suffer from water stress (losing more water via transpiration than can be gained from the soil). Again they have no specific adaptations to overcome this, and can only respond by closing their stomata to prevent further transpiration. This does actually have some benefits as it reduces the surface area of the leaves exposed to the atmosphere, which reduces transpiration. Prolonged periods of dehydration, however, can lead to permanent wilting, cell plasmolysis, and subsequent death. Since mesophytes prefer moist, well drained soils, most crops are mesophytes. Some examples are corn (maize), cucurbits, privet, lilac, goldenrod, clover, and oxeye daisy
How did the phytoplankton change during the El Nino events of 1992-93, 1997-98, and 2015-16?
Answers
The phytoplankton levels dropped enormously during the El Nino events.
Phytoplankton are the autotrophic organisms of the aquatic habitat. They are the beginners of the aquatic food chains. Phytoplankton belong to the category of algae. The species have the capability of buoyancy and float in the upper regions of the sea where sunlight can reach to them.
El Nino was the phenomenon where the temperature of the sea surface went unusually high. This lead to the occurrence of droughts, floods, and several other calamities. Since the temperature of the sea increased, the conditions turned unfavorable for the blooming of phytoplankton and that is why their population reduced.

A segment of DNA is known to contain the following base sequence:3' GATACCTTTGTGTAGTCATCTT 5'a) Write the mRNA that would be transcribed from this DNA fragment.b) Circle the starter and the stopper in your mRNA sequence. Write the sequence of amino acids which would be encoded in translation. Use the mRNA codon table provided.c) Where in the cell do transcription and translation occur?
Answers
a) In order to transcribe the segment of DNA, it is important to note that this process is important for gene expression as a protein. An enzyme called RNA polymerase moves along the DNA until the end of the gene, releasing the mRNA. The DNA has two strands: one that goes from 5' to 3' direction, and another one that goes from 3' to 5' direction. The one that's used for transcription will always be the 3' to 5' one, so we already have the correct strand to work with, as it is a 3' to 5' strand.
However, the mRNA will be assembled in the 5' to 3' direction. Using the same complementary base-pairing rules as in DNA, we will pair Cytosine (C) with Guanine (G), but as there is no Thymine (T) in RNA, we will pair Adenine (A) with Uracil (U).
Therefore, the sequence o mRNA read in the 5' to 3' direction is:
5' CUAUGGAAACACAUCAGUAGAA 3'
b) The starter codon is the AUG codon of a messenger RNA (mRNA). Therefore, the sequence of amino acids will start to be decoded there.
The stopper codon can be one of the three following options: UAA, UAG or UGA. In this case, we can only find the UAG codon.
The codons, then will be:
AUG GAA ACA CAU CAG UAG
Then, we can say that the amino acids translated will be:
Met Glu Thr His Gln
(Methionine - Glutamine - Threonine - Histidine - Glutamine
c) In eukaryotes, transcription occurs inside the nucleus of the cell and translation occurs in the cytoplasm.

Answers
The experimental result that displayed the central pattern generators' involvement in muscle contractions is that 'an insect in which the sensory afferents from the wings have been cut can fly', which suggests that option C is the right answer.
Central pattern generators are neuronal circuits which when activated produce rhythmic motor patterns such as walking, breathing or flying etc. in the absence of sensory signals. Muscle contraction refers to the activities such as tightening, shortening, or lengthening of muscles when some activity is performed by the body. It is caused due to the information signal received by the brain and then returned back to site of stimuli. The experiments conducted displayed that a deafferented locust could generate rhythmic flight motor patterns in response to non-rhythmic stimulation of the nerve cord.

Transcription is mRNA synthesis, which occurs by complementing a segment of the DNA template strand. The translation is the protein growth, which occurs by adding amino acids coded by mRNA codons. C) the polypeptide is 6 amino acids long.
What are transcription and translation?The whole process of protein synthesis includes Transcription and translation.
TRANSCRIPTION
Transcription is the mRNA synthesis process and occurs in the nucleus.
The DNA template strand is read in direction 3'→ 5' to build the mRNA molecule in direction 5'→ 3'. The template strand is the one that is going to be complemented by the mRNA.
mRNA molecule has the same sequence as the DNA coding strand, but it carries uracil instead of thymine.
TRANSLATION
Translation is the process through which polypeptide grows. It occurs in the cytoplasm.
rRNA and tRNA read mRNA in the direction 5'→ 3' and add the correct amino acids to build the new protein.
Amino acids are coded by mRNA codons. Protein synthesis initiates in the AUG start codon -Metionin- and ends when reaching either of the stop codons UAA, UAG, or UGA.
In the exposed example, we have a DNA strand. We know that it is the coding strand, so it has the same sequence as mRNA molecule.
DNA coding strand5' AATCCGTATCTATGACCGTTTGGAAACACTAAGCGGTACTC 3'
mRNA molecule5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'
Kowing mRNA sequence, we can grow the protein.

mRNA start codon5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'
mRNA stop codon5' AAUCCGUAUCUAUGACCGUUUGGAAACACUAAGCGGUACUC 3'
So this protein begins in AUG and ends in UAA.
To grow the protein, we need to separate mRNA codons and find the corresponding amino acids.
mRNA codons ⇒ AUG ACC GUU UGG AAA CAC UAA amino acids ⇒ Met Thr Val Trp Lys His Stop Protein ⇒ Met-Thr-Val-Trp-Lys-HisAccording to this reasoning, the polypeptide is 6 amino acids long. Option C) is correct.

Problems faced by organisms that live in freshwater are without compensating mechanisms, their bodies tend to take in too much water.
Their bodies have a tendency to absorb too much water since freshwater organisms' environments are hypotonic in nature to their cells, which causes the organisms' bodies to do the same. They are unable to manage their tonicity. Only saltwater causes issues for the creatures who inhabit it.
The osmotic principle states that water travels from a location of low solute concentration (hypotonic) to a region of high solute concentration (hypertonic). As a result, the low solute content in the water creates difficulty for freshwater creatures since they have a tendency to use too much water.
