The right answer is balls (globules).

Microtubules are constituent fibers of the cytoskeleton, as are actin microfilaments and intermediate filaments.

The microtubules are formed of tubulin dimers (which have a spherical shape) each consisting of two subunits, tubulin α and tubulin β, linked by non-covalent bonds.

Actin, the main component of microfilaments, is a bi-globular protein that plays an important role in architecture and cell movement. It is present in all the cells of the body (ubiquitous protein), and especially in the muscular cells.

How does a single change in nitrogen base alter the formation of a protein
jasenka [17]


During translation to RNA, the nitrogen bases on the DNA molecule are translated to complementary RNA bases. Afterwards, these bases are again used to form amino acids.
Three bases make up a codon, which codes for a specific amino acid. If a base is changed, the codon will become changed. This will result in a different amino acid being produced in and the primary structure of the polypeptide will be altered.

Suppose that ear length in rabbits is controlled by two additive genes, each of which has two alleles. A true-breeding female (a
PilotLPTM [1.2K]

Answer:

The ear length will be 11 cm.

Explanation:

To know about the ear length of F1 generation, we need to know that how much length in centimeters is contributed by each of the alleles. As we know, each allele has the same value for contributing to the effect of ear length, hence we can divide the ear length by 4 to get our results.

As 6 divided by 4 is 1.5 hence, the allele a and b contribute to 1.5 cm of the length of the ear.

6 divided by 4 is 4, hence the alleles And B contribute to 4 cm of the length of the ear.

The F1 generation will have AaBb genotype hence, the lenght will be 4+1.5+4+1.5 = 11 cm.

Answer:

homologous structures

Explanation:

Homologous structures are organs or skeletal elements of animals and organisms that, by virtue of their similarity, suggest their connection to a common ancestor. These structures do not have to look exactly the same, or have the same function.
