Nicolaus Copernicus was a Renaissance mathematician and astronomer. He was the first to formulate a comprehensive heliocentric cosmology with the Sun, instead of the Earth, as the center of the Universe. The distance of the planets from the sun was in direct relationship to the size of their orbits.

during meiosis, if the parent cell starts with six chromosomes, how many chromosomes will be found in the cell at metaphase i an
mrs_skeptik [129]

These chromatids are divided during anaphase and attracted to the opposite poles of the cell. This division produces 92 distinct chromatids in the cell, which are regarded as 92 chromosomes.

In the cell at anaphase 1, how many chromosomes are there?

chromosomes with 46 in total. From from point on, we will refer to these divided sister chromatids as daughter chromosomes. Each end of the cell has an identical and full set of 46 chromosomes, or 23 pairs of homologous chromosomes, at the end of anaphase; they are still diploid.

Metaphase 1 has how many chromosomes?

chromosomes with 46 in total. In metaphase I, there are a total of 46 chromosomes, each of which is made up of two sister chromatids. There are 23 homologous pairs with two full chromosomes in each. throughout telophase I.

Single strands of nucleic acids are directional, meaning that there are two different ends. What functional groups define the tw
pickupchik [31]

Answer:

The functional groups that define the two different ends of a single strand of nucleic acids are:

B. a free hydroxyl group on the 5' carbon a free hydroxyl group on the 3' carbon

G. a free phosphate group on the 5' carbon

Explanation:

A nucleic acid is a polymer formed of nucleotides that are linked with a phosphodiester bond. The structure of a nucleotide consists on a phosphate group linked to a pentose (ribose in RNA and deoxyribose in DNA) that is also attached to a nitrogenous base. The nitrogenous bases are adenine, guanine, cytosine, thymine (in DNA) and uracil (in RNA).

DNA and RNA are nucleic acids which can be found in a double or single strand presentation.

Nucleic acids are synthesize in the 5’ to 3’ direction, so that is why the convention is that the sequences are written and read in that direction.

The strand of a nucleic acid is directional with an end-to-end orientation, where the 5’ end has a free hydroxyl or phosphate group on the 5' carbon of the terminal pentose, and the 3’ end has a free hydroxyl group on the 3’ carbon on the terminal pentose (ribose/ deoxyribose).
