How could the changes made to the amino acid sequence influence phenotype changes?​

Answers

Due to change in sequence there would be change in Protein structure hence in phenotype

A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.

Protein structure orders

The sequence of a protein is determined by the DNA of the gene that encodes that protein (or that encodes a portion of the protein, for multi-subunit proteins).

A change in the gene's DNA sequence can lead to a change in the protein's amino acid sequence.

Even changing just one amino acid in the protein sequence can affect the protein's overall structure and function. For example, a single amino acid change is associated with sickle cell anemia, an inherited disease that affects red blood cells.

What are the advantages and disadvantages of seed and spore reproduction? Justify whether seed reproduction or spore reproduction is more beneficial for the continuation of an organism.​

Answers

hi have a great day

No Water Required

Seeds do not necessarily need water to germinate and grow, although some require water to soften the seed coat. Large seeds in dry conditions will hold water and allow the growing plant to grow deep roots without the need for rain or additional water.

Fully Developed Embryo

Inside each seed is a fully developed embryo that is ready to begin growing. Many seeds go through a dormancy period, which is a period when the seed will not germinate and begin growing. When conditions are right, the embryo germinates and begins growing. Having an embryo already grown gives a seed plant a better chance at survival as opposed to a spore.

Nourishment

Each seed contains nourishment for the embryo inside the seed. The endosperm is the tissue that surrounds the embryo inside the seed. The embryo uses nourishment provided by the endosperm as a jump start to begin growing.

The Seed Coat

The seed coat is one major advantage seeds have over spores. A spore is a single-celled organism that develops into a plant or fungus when the conditions are right. The spore has no outer protection.
