<u>Gymnosperms and Angiosperms-</u>

Gymnosperms and angiosperms evolved seeds and pollen grains allowing them to live and reproduce in drier habitats than bryophytes and seedless vascular plants.

<u>Properties of gymnosperms and angiosperms-</u>

Gymnosperms are plants which bear seeds without fruits or without any outer coverings. These plants also do not produce flowers. Most plants under this group have needle-shaped leaves. This is an adaptation as these plants grow in colder conditions. Gymnosperms. These plants produce pollen without bearing flowers. Angiosperms are found in almost all climatic conditions. These plants bear flowers and produce seeds that are enclosed inside a fruit or inside an ovary. The seeds of angiosperms have a single cotyledon.

If a mutation occurred that increased the number of exons in a sequence of DNA, what impact would this have on the protein forme
erastovalidia [21]

Answer:

See the answer below

Explanation:

<em>An increase in the number of exons in a sequence of DNA would result in another protein with a longer amino acid sequence.</em>

<u>Exons are the coding part of a gene as opposed to introns. After transcription, the non-coding part of the gene - the introns - are removed by splicing and the exons are joined back together. The final RNA that will undergo translation consists of only exons. </u>

The longer the exons in a gene, the more the codons present in the corresponding mRNA from the gene, and the more the number of amino acids that would be translated from the mRNA. A longer amino acid chain would result in a different protein.

Hence, a mutation that causes an increase in the number of exons in a sequence of DNA would result in a different protein with a longer amino acid sequence.
