Answer:

DNA replication is important because without it, cell division could not occur. With DNA replication, the set of DNA of a cell can be duplicated and then each cell that results from division can have its own entire set of DNA, and cell division can theoretically continue indefinitely.

Describe the process that results in the formation of a tetrad.
goldenfox [79]

Answer:

A tetrad is a four part structure formed during the prophase I of meiosis I which is formed by the homologous chromosomes which is composed of two identical chromatids.

The tetrad formation takes place when a proteinaceous meiosis-specific nuclear structures called synaptonemal complex is formed between two homologous chromosomes which mediates the tight associations of the  homologous chromosomes.

The synaptonemal complex consists of two ladder like lateral elements which attaches the chromatin of the homologius chromosomes. The central region of the synaptonemal complex is composed of the transverse filaments and the central element which bridge the space between the the lateral elements.

This attachment of the chromatin to the synaptonemal complex mediates the chromosome pairing and form tetrad.

  •   plq (Double Recombinant gamete)  

Explanation:

Cross:

Parentals) pLq/PlQ x plq/plq

Gametes) pLq (Parental)          plq (Parental)

                PlQ (Parental)

                pLQ (Recomb)

                plQ (Recomb)

                PLq (Recomb)

                Plq (Recomb)

                PLQ (Double Recom)

                plq (Double Recom)  

Parentals)

  • p----L-----q
  • P.....l........Q

Simple recombinant)

Recombination occurs between p and L, OR between l and q.

  • P----L-----q
  • p......l.....Q
  • p----L-----Q
  • P.....l........q

Double recombinant)

Recombination occurs between p and L, AND between l and q.

  • p-----l------q
  • P......L.......Q

Ad libitum [116K]

Answer:

According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.

Explanation:

G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.

G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.
