Pie
What pathway would likely predominate in a mutant in which ci was overexpressed relative to a wild-type virus? - Lytic pathway; when the virus infects the cell, that is, it gets into it, clones or forms thousands of viruses and then breaks the capsid and continues parasitizing other cells to follow the same procedure.<span>in a mutant in which ci was underexpressed relative to a wild-type virus?</span> Lysogenic; that is when the genetic material of the virus is coupled to the genetic material of the cell, then the cells b, daughters of this, will be possessors of the virus (genetically).

Explain the role of crossing over in terms of achieving genetically varied offspring​
Annette [7]

Answer:

Crossing over is a process that happens between homologous chromosomes in order to increase genetic diversity. During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material.Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

The enzyme lactase breaks the sugar lactose into which compound(s)
Sloan [31]
The answer is galactose and glucose.

Lactase is considered as B- galactosidase  enzymes that breaks down and form galactosidic bonds on sugars. This is present in the digestive system and hydrolyze the lactose present in the food into glucose and galactose. Lactase is present in wide number of animals and microorganism. Bacillus, Kluyveromyces and Aspergillus are commercially cultivated to produce lactase for industrial purposes.

Chromosome 21 figure D is the result of a process known as________
Softa [21]

Answer:

Chromosome 21 in figure D is the result of a process known as non-disjunction

Explanation:

Meiosis is the process of cell division that serves to obtain gametes, cells with exactly half the chromosome load of the species. This process involves the equal distribution of chromosomes in each daughter cell.

Non-disjunction is an alteration in the separation of the sister chromatids during meiosis, resulting in a gamete with non-separated sister chromatids, which when joined to a normal gamete can produce an organism with an extra chromosome.

In the karyotype shown in the photo, the non-disjunction in chromosome 21 produces a trisomy, a type of aneuploidy seen in Down syndrome.
