13) When mRNA is "processed", what are the pieces of mRNA that are cut out and stay in the nucleus?

Introns

Exons​

Answers

Answer 1

Answer:

Introns

Explanation:

The coding region of the gene is the part of the gene that is transcribed. However, not all of the gene makes the final mRNA. There are sequences called exons and introns in the coding region of the gene.

The pre-mRNA contains transcribed sequences of both the introns and exons. However, the introns are removed from the final mRNA by splicing. The final mRNA that is translated to the protein only contains exons. An illustration is attached to illustrate this.

What is Cellular Respiration and what is the formula for it?

Answers

Answer:

Summary. Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).

Explanation:

i said it first

Cellular respiration is the process in which the cells convert sugars into energy. The formula for cellular respiration is: C6H12O6+6O2>6CO2+6H2O

Answers

Answer:

N2

Explanation:

Although the atmosphere is mostly made up of nitrogen, it is in the form of a gas known as dinitrogen N2. Plants cannot use this form. Dinitrogen, or atmospheric nitrogen, can also be found in the soil. In addition to dinitrogen, other inorganic and organic forms exist in the soil as well.

In the atmosphere, nitrogen exists as a gas (N2)

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?

A.silent

B.missense

C.nonsense

D.insertion

Answers

Answer:

A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.

Explanation:

In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.

In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.

For the other options:

Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.

Answer:

Silent

If energy is released, free energy must be what?

Answers

Answer:

If energy is released during a chemical reaction, then the change in free energy from the conversion of the reactants to the products, signified as ΔG (delta G) will be a negative number.

Explanation:

Hope it helped!

Answer:

If energy is released during a chemical reaction, then the resulting value from the above equation will be a negative number. In other words, reactions that release energy have a ∆G < 0. A negative ∆G also means that the products of the reaction have less free energy than the reactants because they gave off some free energy during the reaction.

Answers

Answer: Okay so Photosythesis is the process used in most plants (except carnivorus plants) when the plant uses its chroloplasts (cells only plants have) to convert sunlight into sugar which makes food for the plant so it can live without having to hunt for food.

Explanation:

I hope this helps sorry if it doesn't :(

Have a good day :)

Stay motivated :)

Answer:

Photosynthesis is the process used by plants, algae, and certain bacteria to convert the energy from sunlight (or other usable light sources) into chemical energy. Chemical energy is the energy these organisms use for different metabolic processes. During this process, they take in the carbon dioxide produced by all breathing organisms and release oxygen, which we breathe in once again, into the atmosphere.

Describe the two stage life cycle of plants: the gemetophyte stage and the sopophyte stage

Answers

Plants have what is called an alternation of generations in their life cycle. The two stages are called the sporophyte generation and the gametophyte generation. The sporophyte generation is diploid (has pairs of chromosomes). It produces spores by meiosis (reduction division), so the spores are haploid (contain only one chromosome from each pair). The spores divide by mitosis to produce a multicellular, haploid gametophyte generation. The gametophyte produces gametes (by mitosis) which fuse during fertilization to form a diploid zygote. This then develops into the sporophyte, completing the life cycle.
