DNA Transcription and Translation Pre final test 8B

What is the process of transcription?

• Converting mRNA into DNA

• Breaking down mRNA into nucleotides

• Copying DNA into mRNA

• Creating proteins from mRNA

What is the process of translation?

• Conversion of DNA into amino acids

• Conversion of mRNA into amino acids

• Conversion of tRNA into amino acids

• Conversion of rRNA into amino acids

What are codons and anticodons?

• Codons are sequences of three nucleotides on mRNA that correspond to specific amino acids. Anticodons are sequences of three nucleotides on tRNA that are complementary to the codons on mRNA.

• Codons are sequences of three nucleotides on tRNA that correspond to specific amino acids. Anticodons are sequences of three nucleotides on mRNA that are complementary to the nucleotides on tRNA.

• Codons are sequences of three nucleotides on mRNA that correspond to specific nucleotides. Anticodons are sequences of three nucleotides on tRNA that are complementary to the codons on mRNA.

• Codons are sequences of three nucleotides on tRNA that correspond to specific amino acids. Anticodons are sequences of three nucleotides on mRNA that are complementary to the codons on tRNA.

How do codons and anticodons relate to each other?

• Codons and anticodons are identical to each other.

• Codons and anticodons are related through complementary base pairing.

• Codons and anticodons are unrelated to each other.

• Codons and anticodons are only found in RNA.

What is a mutation in the context of DNA?

• A temporary change in the DNA sequence.

• A change in the RNA sequence.

• A change in the protein sequence.

• A permanent change in the DNA sequence.

How can mutations affect protein synthesis?

• Mutations can only affect DNA replication, not protein synthesis.

• Mutations have no effect on protein synthesis.

• Mutations can cause the protein synthesis process to stop completely.

• Mutations can alter the DNA sequence, leading to changes in mRNA and ultimately affecting the protein synthesis process.

What are the consequences of mutations in DNA?

• Mutations in DNA only affect physical appearance.

• Mutations in DNA have no consequences.

• Mutations in DNA can be reversed easily.

• Mutations in DNA can lead to genetic disorders, changes in physical traits, increased susceptibility to diseases, and potential impact on the functioning of proteins and enzymes.

Use the next fragment of gen SRY (testis-determining factor) to solve the next case. In firts time you need make a transcription. What is the sequence of RNAm in according to the next sequence :

GAA TAT TCC CGC TCT CCG GAG AAG CTC TTC CTT CCT TTG CAC TGA AAG CTG TAA CTC TAA

Use the before sequence obtained of RNAm to convert to aminoacid sequence. Use the genetic code available in the next link https://biomodel.uah.es/biomodel-misc/codgen/inicio.htm
