How do fungi beneﬁt from being able to reproduce both asexually and sexually?

Alekssandra [29.7K]

Asexual reproduction is an advantage because they don't need to depend on contacting a suitable mate, or expand energy producing gametes and attractions, in order to spread .

sexual reproduction is an advantage because it enables the exchange of genetic information and produces variety in the offspring that makes them more resilient and capable of adapting to changes in their environment .

Neurons have special proteins in their cell membranes that allow them to generate electric current. Are these proteins most like

V125BC [204]

Answer:

Sodium-Potassium pumps (proteins that help neurons generate electricity) are produced by ribosomes on the rough endoplasmic reticulum (ER).

Explanation:

Sodium-Potassium Pump (NA+/K+):

The Na+/K+ Pump is a transmembrane channel protein, responsible for maintaining the concentration gradient of sodium and potassium ions in the intra and extracellular environment. This is achieve by pumping 3 Na+ outside and 2 K+ inside the cell at the cost of one ATP. In neurons, these channels help in generating an action potential across the cell membrane that gives rise to a nerve impulse.

Production of Transmembrane proteins:

All membranes and their proteins are produced by the ribosomes on the rough ER. The rough endoplasmic reticulum contains the enzymes required for lipid synthesis; and as cell membranes are made of lipids, the ER is the most suitable location for synthesis. Membrane proteins, particularly, transmembrane proteins like the Na+/K+ pump possess hydrophobic surfaces that don't dissolve in the cytoplasm but readily attach to the ER surface from where they can be transported wherever required.

Which of the following best compares rhizoids and fruiting bodies in Fungi?

Bad White [126]

The correct answer is B. Rhizoids absorb water and nutrients, while fruiting bodies release spores.

Rhizoids of Fungi are similar to root hairs on vascular land plants. Rhizoids, release digestive enzymes and absorb digested organic material, so it is a feeding organ.
Fruiting body or sporocarp is a structure that is part of the sexual phase of a fungal life cycle and it contains spore-producing structures.

Help please! DNA Assignment

vovangra [49]

Answer:

DNA Replication:

Replicate the following strand of DNA:

Original DNA: A T G A A C CA T T C A G T A T G G

Complementary DNA:

Remember that the complimentary base pairs in DNA are Adenine-Thymine and Guanine-Cytosine, or A-T and G-C. This means that if the original sequence is:

A T G A A C C A T T C A G T A T G G

Then the compliment is (replace with the opposite base pairs):

T A C T T G G T A A G T C A T A C C

Transcription:

Transcribe the DNA to make an mRNA molecule

COMPLIMENTARY DNA:

mRNA Molecule:

So if our complimentary DNA (antisense stand) is T A C T T G G T A A G T C A T A C C then to transcribe, we basically create another complimentary strand, but for mRNA, we use Uracil instead of Thymine:

A U G A A C C A U U C A G U A U G G

Translation:

Translate the mRNA into the corresponding amino acids.

mRNA MOLECULE:

AMINO ACID:

Using the DNA sequence provided, determine the amino acids.

Next, take each codon (3-base set) to the table and record the corresponding protein:

A U G = Methionine (start)

A A C = Asparagine

C A U = Histidine

U C A = Serine

G U A = Valine

U G G = Tryptophan

ORIGINAL DNA: A T G G G T C T A G C G A A A G A T

Complementary DNA:

mRNA DNA Molecule:

Amino Acid:

And we do it all again:

A T G G G T C T A G C G A A A G A T = original DNA

T A C C C A G A T C G C T T T C T A = complementry DNA

A U G G G U C U A G C G A A A G A U = mRNA

A U G = Methionine (start)

G G U = Glysine

C U A = Leucine

G C G = Alanine

A A A = Lysine

G A U = Aspartate
