Answer:

This is most likely due to a mutation in a maternal effect gene.

Explanation:

The genes of maternal effect are the result of a special genetic inheritance that is managed by genes present only in the mother's body, of a certain individual. These genes are responsible for determining some specific conditions in the egg, generating some changes in the individual's genotype and phenotype. In summary, these genes are responsible for contributing to the phenotype of an individual directly related to the mother's genotype.

Like any gene, genes of maternal effect can mutate, generating some phenotypic anomalies. An example of this is the existence of two tails in an abnormal embryo of Drosophila.

1 so that all parts of the plants and animals Get Enough nutrients and oxygen

2 the pigment called haemoglobin makes it red

3 waste products such as urea will cause great harm to the body is not excreted

4 the heart pumps blood the blood contains nutrients and oxygen facial transported to other organs so that the cells can operate

5 transpiration is the loss of water by plants. it helps with cooling down the plant after photosynthesis. Just the Way We sweat

This subcellular structure functions to modify gene expression products before they are shuttled out of the cell via exocytosis.

Over [174]

Answer:

The correct answer will be- Golgi apparatus

Explanation:

The proteins are synthesized in the ribosomes whether they are attached to the endoplasmic reticulum or free. These synthesized proteins enter the lumen of the endoplasmic reticulum where they get packaged to go to Golgi apparatus.

The Golgi apparatus is the site of post-translational modification of the secreted proteins like ubiquitination, acetylation, phosphorylation and many others.

Thus, the Golgi apparatus is the correct answer.
