Of the following, which is most likely to be considered a developing nation?

All proteins are synthesized by ribosomes in the cell. some ribosomes float freely in the cytosol, while others are bound to the

Dennis_Churaev [7]

Ost proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes.
As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.

A true-breeding plant with inflated pods and yellow pods is crossed with a plant that has constricted and yellow pods. Draw a

xenn [34]

Answer: Sysy × Sysy i.e. all are genotypically heterozygous, inflated, and yellow

Explanation:

Punnett squares are a diagrammatic means of determining traits of hybrid offspring produced via crosses in genetic breeding. The parental genotypes and phenotypes are usually known, and these typically follow standard Mendelian ratios and inheritance.

Mendelian genetics focus on trait inheritance, or heritability. These traits are packaged out into its own gamete, inherited by themselves and often show dominance, where one's effect may mask those of another trait.

These are called the Law of Segregation, Independent assortment and Dominance respectively.

For this cross...

Parent generation or P generation:

gametes: Y → pod color green dominant (Y), yellow recessive (y)

S→ pod size; inflated dominant (S), constricted recessive (c)

Assumptions...

True breeding plants are homozygous, with identical sets of alleles
The other parent is heterozygous, as it was not said to breed true

P generation: SySy × sysy

yellow, inflated × yellow, constricted

F1 generation: Sysy × Sysy ...(from punnet square)

phenotype: yellow, inflated × yellow, inflated

∴ all are genotypically heterozygous, inflated, and yellow

What is a mutation? What causes mutations? What is the evolutionary importance of mutations?

mihalych1998 [28]

Answer:

A mutation is:

the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes.

What causes a mutation:

Acquired (or somatic) mutations occur at some time during a person's life and are present only in certain cells, not in every cell in the body. These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division.

Short Version: environmental factors, cell division, Change in DNA

What is the evolutionary importance of mutations:

A mutation is a change in DNA, the hereditary material of life. An organism's DNA affects how it looks, how it behaves, and its physiology. So a change in an organism's DNA can cause changes in all aspects of its life. Mutations are essential to evolution; they are the raw material of genetic variation.

Short Version: Without mutations then we wouldn't have evolution meaning if one new predator were to be introduced it can completely whipe out that entire species.

Hope this helps
