Answer:

The phenotype of an organism reflects all the traits that are actually expressed.

Explanation:

Phenotype refers to the visible or evidentiable characteristics that depend on the genotype, which is stored in the DNA. Phenotypic expression, mainly determined by genes, also depends on the influence of the environment on the individual.

Although the phenotype expresses characteristics such as skin, eye and hair color, height or shape of the nose, some characteristics are not entirely visible, such as specific functions or synthesized proteins.

The other options are not correct because:

Represents its genetic composition: this is genotype.
Phenotype occurs in all individuals, both dominant and recessive.
Many phenotypical characteristics are visible.

Template DNA 5' GATTCAGAGA 3'

Complemntary strand 3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

codes of mRNA GAU, UCA, UAG

Explanation:

5' GATTCAGAGA 3' is the example of DNA strand having the sequence.

The DNA strand is leading strand and is in 5' to 3' direction

the complementary DNA strand is formed in 3'to 5' direction as the strand of 5' to 3' acts as a tempelate for complementary strand.

During replication which is semiconservative a new template is formed by adding the nucleotides to the growing strand.

DNA synthesis always takes place in 5' to 3' direction.

5' GATTCAGAGA 3'

3' CTAAGTCTCT 5' Complemntary strand

Transcription is a process in which DNA sequence is transcribed into mRNA which carries codes for amino acids.

The 5' to 3' strand is called sense strand

3' to 5' strand is called antisense strand. mRNA is transcribed from antisense strand and is a copy of sense strand.

so the transcribed DNA strand as mRNA will be shown as:

3' CTAAGTCTCT 5'

5' GAUUCAGAGA3' mRNA strand

GAU codes for = Aspartate

UCA codes for = serine

GAG code for = glutamate (when due to mutation GAA will become GAG)

A will not code as it is not in triplets.

In an experiment, shara feeds her rat different brands of rat food (brands x, y, and z) each for 2 weeks and weighs the rat over

Advocard [28]

The variables are defined as the factors in an experiment, which are liable to change. The variable can be dependent or independent. The Independent variable is a variable, which is unaffected by the changes in the other variables.

In this case, the brand of the food Shara feeds to the rats is independent factor, but it is changes in the system, so, it is an independent variable.

The effect on the weight of the rat is dependent on the brand of food they are consuming. So, the weight of rats is dependent variable.
