The repeating stages a cell experiences, including cell division, compose the cell cycle.

Life cycle of the cell (cell cycle) can be divided in interphase and mitotic phase.

Interphase can be subdivided into:

• G1 phase characterized by the growth of the cell

• S where DNA replication occur

• G2 phase final preparation for mitosis.

Mitotic or M phase consists of:

• Prophase-condensation of chromosomes and mitotic spindle formation

• Metaphase-alignment of the chromosomes

• Anaphase- Sister chromatids are pulled apart by the mitotic spindle

• Telophase-each pole of the cell contain full set of chromosomes.

Two new cells are formed after cytokinesis.

A gene includes the sequence AGAACT. When it is transcribed, what will the RNA sequence be? A. UCUUGA B. UGCCGU C. UCUUTC D. TCT

Margaret [11]

Answer:

Explanation:

The correct option would be A.

According to the base-pairing rule, Adenine (A) always pairs with Thymine (T) (or Uracil in the case of RNA) while Guanine (G) always pairs with Cytosine (C).

Hence;

A-U

G-C

A-U

C-G

T-A

Therefore, AGAACT would be transcribed to UCUUGA.

What is allele frequency?

IgorLugansk [536]

Answer:

The correct answer would be - D. the distribution of alleles in a population.

Explanation:

Allele frequency in population genetics is the term used to provide the amount of the different alleles in particular loci. In other words, it is the distribution of alleles in a population.

The term allele frequency refers to the fraction of the copies of the gene of the alleles in a known population. It can be calculated by the number of allele present of interest divided by total number of alleles in a population.
