Describe how meiosis and mitosis are similar and different. Provide at least two similarities and 3 differences.

1 answer:

7 0

Differences
1. Meiosis occurs in two divisions, resulting in four haploid cells. Mitosis, however, occurs in one division, resulting in two diploid cells.
2. Mitosis produces body cells, which are used for purposes of growth and repair. Meiosis, however, produces gametes, which are used in sexual reproduction.
3. Mitosis produces two identical daughter cells, but meiosis increases genetic variation by undergoing crossing over an independent assortment. The resulting daughter cells of meiosis are genetically unique to the parent cell.

Similarities
1. Both processes are completed in a specific order that is heavily monitored to ensure that errors do not occur.
2. Both processes proceed DNA replication as well as growth phases.
3. Both processes have at least one phase in which the sister chromatids separate; in the case of meiosis, it is anaphase II, and in mitosis, it is anaphase.

Two nucleotides on the same strand form a __________ bond while two complimentary bases on opposite strands form ____________ bo

Anna [14]

Two nucleotides on the same strand form a Phosphodiester bond while two complimentary bases on opposite strands form Hydrogen bonds. An a-t base pairing forms 2 such bonds.

The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.

Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.

Can molecules be made of one or more particles?

Tasya [4]

A molecule is the smallest particle of a substance that exists independently. Molecules of most elements are made up of only one of atom of that element. Oxygen, along with nitrogen, hydrogen, and chlorine are made up of two atoms. ... The oxygen molecules are bonded or stuck together.
