Guest lecture / keynote speech Nas clases maxistrais o profesor explicará os contidos fundamentais de cada tema do programa e sinalará as actividades asociadas a este. Estas incluirán a consulta de bibliografía, a resolución de boletíns de cuestións e problemas, ou a eleboración dun traballo que o alumno deberá elaborar en grupo ou individualmente.
Laboratory practice Laboratory practices related to the development of chromosomes and karyotypes were developed.
It will be know the cell cultures, making the karyotype and develop some method of chromosome banding.
Mixed objective/subjective test A proba mixta consistirá en preguntas curtas ou de tipo test e resolución de problemas.
Workbook O alumno leerá un ou dos artigos científicos para ampliar e profundizar nos contidos tratados no temario, e que expondrán na presentacion oral.
Practical test: Se valorará os conocimientos adquiridos durante as prácticas de laboratorio.
Oral presentation Consistirá na exposición oral de un ou dos artigos científicos, acompañada de una presentación en power point, que posteriormente aloxaráse na plataforma Moodle da materia, para a súa consulta de cara a completar ou ampliar contidos da materia. A exposición será de un máximo de 10-12 minutos. Esta actividade realizarase por parellas. Ambos membros do grupo deben repartirse a exposición do traballo.

Assessment comments

Laboratory practices are mandatory.

To pass the subject, the student must obtain at least 50% of the score assigned to the mixed test and another 50% of that of the laboratory practices.

It will be considered NOT PRESENTED when the student has not participated in more than 20% of the scheduled assessable activities. This criterion applies to the January call. In the July call, to obtain the grade NOT PRESENTED, it will be enough to not appear for the objective tests (theory and practical exams).

For the evaluation of the July call, the student, in addition to the theory and practical exams, must present the bulletins of solved problems and the power point presentation of the oral presentation. In the event that these last two activities were already evaluated in the January call, the grade obtained will remain for July.

For students with part-time dedication and exemption from attendance, the teacher will adopt the measures that he deems appropriate to avoid damaging her grade (flexibility in the delivery dates of the assessable activities). Instead of the oral presentation, these students will make a 2-3 page summary that must be delivered in pdf to the teacher for evaluation.

The fraudulent performance of tests or assessment activities will directly imply the application of current regulations in the UDC.

Other comments

Attendance at the master classes enables the treatment of doubts or questions that may arise in the course of the explanations, facilitating the understanding of the topics. The study must contemplate the habitual consultation of at least the recommended bibliography. Study and group work favors understanding and develops a critical spirit. Doubts and difficulties raised by any aspect of the subject must be resolved as soon as possible, raising them in face-to-face classes or attending individualized tutorials. Given that part of the recommended bibliography for this subject is in English, it is advisable to have knowledge of this language, at least at the level of comprehension of written texts.

Green Campus Program

Green Campus Program of the Faculty of Sciences

To help achieve a sustainable environment and comply with point 6 of the "Environmental Declaration of the Faculty of Sciences (2020)", the documentary works carried out in this matter:
to. They will be requested mainly in virtual format and computer support.

b. If done on paper:

- Plastics will not be used

- They will be printed on both sides.

- Recycled paper will be used
- Drafts will be avoided.
