Answer from: kenzie5889

The combinations of gametes that could be produced by a heterozygote for both of the traits is PT, pT, Pt, and pt.

In a gene, two alleles are responsible for the genotypic appearance. According to Gregor Mendel, one allele called dominant allele masks the phenotypic expression of the other allele called recessive allele. An heterozygous genotype is the genotype that contains two different alleles of the same gene. For example, in this question, P represents purple flowers while p represents white and T represents tall plants while t represents dwarf. This means that a heterozygous combination for both genes will look like: PT, pT, Pt, and pt..

Answer from: maddynichole2017

The combinations of gametes that could be produced from heterozygous individuals for both traits are PT, Pt, pT and pt.

Explanation:

An individual is heterozygous for two traits, flower color and stem height, with a PpTt (dihybrid) genotype and a phenotype showing the dominant traits, purple flowers and tall stem.

The genes of this individual for the above-mentioned traits contain different alleles, and taking into account the independent segregation of characters, the alleles present in its gametes could be:

Both dominant alleles: PT One dominant and one recessive allele Pt or pT Both recessive alleles: pt

Therefore, the traits of its offspring will depend on the alleles for those traits present in the gamete to which they are combined.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.

Answer from: Quest

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle

Put the following processes of protein synthesis in the correct order: - dna strands unwind and separate - mrna copies dna according to complimentary base pairing - trna's anticodons bring amino acids to the corresponding mrna codons - amino acids bind to each other making a protein - mrna leaves the nucleus - a stop codon is reached, the newly formed protein is released to go do its job for the cell
