If 14c-labeled uracil is added to the growth medium of cells, what macromolecules will be labeled? if 14c-labeled uracil is added to the growth medium of cells, what macromolecules will be labeled? rna both dna and rna dna phospholipids proteins

RNA

Explanation:

Uracil is one of the pyrimidine bases found in RNA. It is substituted by thymine in DNA.

Hence, if -labeled uracil base is added to the growth medium of a cell, the uracil will be utilized in the synthesis of RNA and consequently, the synthesized RNA will become -labeled accordingly.

The correct option is RNA.

the most common type of reef is the fringing reef. this type of reef grows seaward directly from the shore. they form borders along the shoreline and surrounding islands.

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
