Prophase is the first phase of mitosis and this is also the process that the duplicated genetic material separates. They are carried into the nuclei of the two identical daughter cells. Thus, the answer to this item is letter B. The nuclear membrane breaks down.

Two short-haired guinea pigs have several offspring over the course of a few years. Out of 100 offspring, 25 of them have long h
Llana [10]

The genotype of the short-haired parents that produced some long hair offsprings is probably heterozygous.

<h3>What is heterozygosity?</h3>

Heterozygous means an organism which has two different alleles of a given gene.

An organism that is heterozygous posseses two different alleles of the same gene. For example, in this gene coding for hair length;

  • L represents short hair (dominant)
  • l represents long hair (recessive)

Therefore, if two short-haired parents produce 100 offsprings and 25 of them are long-haired, it means that they were probably heterozygous for the short hair.

What is the difference between homozygous and heterozygous
Musya8 [376]
Homozygous means "the same" and Heterozygous means "different". If a pheno type is homozygous, for example, it could be XX or xx, while heterozygous could be Xx. Hope that helps.

Ostrovityanka [42]

Answer:

B.

that the biodiversity of the coral reefs will decrease if global temperatures continue to increase.

Explanation:

Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Occupying less than one percent of the ocean floor, coral reefs are home to more than twenty-five percent of marine life.

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

Which cell junctions form a barrier to the passage of materials?
kkurt [141]

Answer:

The correct answer is - tight junctions.

Explanation:

Tight junctions are one of the cell-cell junctions that make a barrier to the passage of material which is a present in epithelia. This barrier is impermeable to most of the materials with soluble molecules. This barrier is made up of the occludin and claudin proteins.

Tight epithelia have tight junctions and examples of such junctions are the distal convoluted tubule or DCT, and the collecting duct of the nephron in the kidney.

Thus, the correct answer is - tight junctions.
