Answer: An error during transcription could produce a shorter protein or induce changes in the protein's sequence.
Explanation: Transcription is the process of single-stranded RNA synthesis from a DNA template (gene). During this process, RNA polymerase reads the DNA template and synthetize RNA, keeping the sequence. The RNA sequence will be reading later by ribosomes and protein will be produced. An error in transcription could produce changes in codons that are sequences of 3 nucleotides that determine aminoacids of the protein, and that would change protein folding and inactive it. Another possible result would be that error in transcription produce a premature stop codon that cause a shorter inactive protein.
Cohesion causes water molecules to stick to each other. Cohesion is the attraction of like molecules
Answer:
Bryophytes, lycophytes, ferns, whisk ferns, and horsetails. (Ans. A)
Explanation:
Seedless vascular plants: They are defined as the plants which contains developed specialized tissues known as vascular structure for transportation of nutrients and water. They are known as higher plants because they include from flowering plants to conifer trees (growing seeds) to fern (do not grow seeds).
Seedless vascular plants are divided into four plant divisions:
1) Psilophyta
2) Lycophyta
3) Sphenophyta
4) Pterophyta
Seedless vascular plants includes horsetail and clubmosses, these plants are not producing flowers or seeds. Spores of these plants are very lightweight with the help of this they are disappearing quickly in the wind.
