Istilah yang digunakan untuk menggambarkan proses bertahap DNA-->RNA-->Protein:
- A.
Transkripsi
- B.
Dogma sentral
- C.
Tranlasi
- D.
Ekspresi
- E.
Terminasi
Correct Answer
B. Dogma sentralExplanation
The term "Dogma sentral" is used to describe the process of DNA being transcribed into RNA and then translated into protein. This term refers to the central dogma of molecular biology, which states that genetic information flows from DNA to RNA to protein. It describes the fundamental process by which genetic information is transferred and expressed in living organisms.Rate this question:

Segmen DNA yang biasanya terletak di bagian hulu daerah pengkode suatu gen dan berfungsi sebagai elemen pengaturan ekspresi gen:
- A.
Promoter
- B.
Kodon “start”
- C.
Kodon “stop”
- D.
5’UTR
- E.
Ekson
Correct Answer
A. PromoterExplanation
A promoter is a DNA segment that is typically located at the upstream region of a gene and functions as a regulatory element for gene expression. It initiates the transcription process by providing a binding site for RNA polymerase, which then starts transcribing the gene into RNA. The promoter region contains specific sequences, such as the TATA box, that help in recruiting the transcription machinery and regulating the level of gene expression. Therefore, the promoter is responsible for controlling when and how much a gene is expressed.Rate this question:

Daerah DNA dalam gen eukariotik yang menyandi polipeptida disebut:
- A.
Intron
- B.
Ekson
- C.
RRNA
- D.
5'UTR
- E.
TRNA
Correct Answer
B. EksonExplanation
The correct answer is "ekson." In eukaryotic genes, the DNA region that encodes polypeptides is called an exon. Exons are the coding sequences that are transcribed into mRNA and eventually translated into proteins. They contain the necessary information for protein synthesis. In contrast, introns are non-coding sequences that are transcribed but are removed during RNA processing. rRNA, 5'UTR, and tRNA are not directly involved in encoding polypeptides.Rate this question:

Molekul di bawah ini berperan membawa asam amino dalam proses sintesis protein:
- A.
MRNA
- B.
RRNA
- C.
HnRNA
- D.
RNA polimerase
- E.
TRNA
Correct Answer
E. TRNAExplanation
tRNA (transfer RNA) plays a crucial role in the process of protein synthesis. It carries specific amino acids to the ribosomes, where they are added to the growing polypeptide chain according to the mRNA sequence. Each tRNA molecule has an anticodon that is complementary to a specific codon on the mRNA, ensuring that the correct amino acid is added to the chain. Therefore, tRNA is directly involved in the translation of the genetic code from mRNA into a sequence of amino acids, which ultimately leads to protein synthesis.Rate this question:

Pengaturan gen-gen mana yang akan disalin menjadi RNA adalah salah satu cara pengaturan ekspresi gen diferensial yang disebut:
- A.
Trankripsi gen secara diferensial
- B.
Pemrosesan RNA secara selektif
- C.
Translasi mRNA secara selektif
- D.
Modifikasi protein secara diferensial
- E.
Semua jawaban benar
Correct Answer
A. Trankripsi gen secara diferensialExplanation
Transcription gen secara diferensial adalah salah satu cara pengaturan ekspresi gen diferensial di mana hanya gen-gen tertentu yang akan disalin menjadi RNA. Ini berarti bahwa hanya sebagian gen yang akan mengalami proses transkripsi menjadi RNA, sementara gen lainnya tidak. Pilihan lain, seperti pemrosesan RNA secara selektif, translasi mRNA secara selektif, dan modifikasi protein secara diferensial, tidak menjelaskan konsep ini dengan tepat.Rate this question:

Triplet nukleotida, pada posisi 34-36 pada suatu molekul tRNA, yang akan membentuk pasangan basa dengan triplet nukleotida molekul mRNA dalam proses translasi:
- A.
Antikodon
- B.
Daerah pengkode (coding sequences)
- C.
Kodon
- D.
Promoter
- E.
Semua jawaban benar
Correct Answer
A. AntikodonExplanation
The antikodon is a triplet of nucleotides found on a tRNA molecule that pairs with a triplet of nucleotides on the mRNA molecule during translation. This pairing is necessary for the correct placement of amino acids during protein synthesis. The antikodon and codon (the triplet on the mRNA) have complementary bases, allowing for specific base pairing and the formation of a stable mRNA-tRNA complex. Therefore, the antikodon is the correct answer because it directly relates to the process of translation and the formation of the mRNA-tRNA complex.Rate this question:

Semua asam amino mempunyai kodon lebih dari satu, KECUALI asam amino:
- A.
Leusin
- B.
Isoleusin
- C.
Serin
- D.
Metionin
- E.

Pewarisan ketidaknormalan disebabkan oleh adanya gen pada salah satu X kromosom yang mengalami ketidaknormalan:
- A.
Autosomal dominan
- B.
Autosomal resesif
- C.
Modified autosomal
- D.
Sex-link inheritance
- E.
Semua jawaban benar
Correct Answer
D. Sex-link inheritanceExplanation
Sex-link inheritance refers to the inheritance of traits or disorders that are determined by genes located on the sex chromosomes, particularly the X chromosome. In this case, the correct answer suggests that abnormal inheritance is caused by a gene on one of the X chromosomes that undergoes abnormality. This type of inheritance pattern is often associated with disorders such as color blindness and hemophilia, which are more commonly seen in males due to their possession of only one X chromosome.Rate this question:

Pengujian/test yang dilakukan dalam genetika reproduksi:
- A.
Carrier testing
- B.
Preimplantation diagnostic
- C.
Prenatal diagnosis
- D.
Newborn screening
- E.
Semua jawaban benar
Correct Answer
E. Semua jawaban benarExplanation
The correct answer is "Semua jawaban benar" which means "All answers are correct" in English. This means that all of the testing methods mentioned in the question - carrier testing, preimplantation diagnostic, prenatal diagnosis, and newborn screening - are part of the genetic reproductive testing.Rate this question:
