Methodologies
Methodologies Description
Guest lecture / keynote speech In each class the contents of the program will be exposed. The teachers' presentations will be incorporated into the Moodle platform.

CONTINGENCY PLAN: the lectures will be held via TEAMS at the previously approved official hours
Long answer / essay questions Written test in which any aspect addressed in the theoretical and practical teaching will be dealt with.


CONTINGENCY PLAN: PRESENTIAL students will take the exam via TEAMS on the date and times previously established and approved
Document analysis Students will read a series of research articles related to any aspect of the syllabus. This work will be reflected in a power point elaboration that will be presented and exhibited in the classroom.

CONTINGENCY PLAN: students will present their work via TEAMS, in case of confinement.
All works will be uploaded to the Moodle platform, after review by the subject teachers.
Laboratory practice The laboratory practices are the following:
Practice 1: PCR amplification of DNA sequences
Practice 2: electrophoresis of PCR products
Practice 3: Work with bioinformatics tools for the analysis of the sequences of the PCR products
CONTINGENCY PLAN: in case of confinement, the practices will be reconverted or replaced in computer analysis working with different genomic sequences.

Assessment comments
<p>Laboratory practices are mandatory.</p><p>To pass the subject, the student must obtain at least 50% of the score assigned to the essay / development test and another 50% of that of the laboratory practices.</p><p>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).</p><p>For the evaluation of the July call, the student, in addition to the corresponding exams, must present the power point presentation of the oral presentation. In the event that this activity was already evaluated in the January call, the grade obtained will remain for July.</p><p>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.</p><p>&nbsp;</p>

Other comments
Attendance to 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 in-person 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 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)", documents requested as part of the course will be turned in electronically. If printed, plastic covers will not be used, they will be printed on both sides on recycled paper. Drafts will be avoided.
