Question

if the codon is gau, the anticodon is *
cta
gau
cua
ctt

true or false: if there is damage to the dna there will always be damage to the * protein
true
false

central dogma of molecular biology is summarized as: *
proteins - rna - dna
rna - dna - proteins
dna - rna - proteins
proteins - dna - rna

Explanation:

Determine the anticodon for GAU

The codon is GAU (RNA). The anticodon on tRNA pairs with the codon using RNA base-pairing rules:

• Guanine (G) pairs with Cytosine (C)
• Adenine (A) pairs with Uracil (U)
• Uracil (U) pairs with Adenine (A)

Therefore, the complementary anticodon to GAU is CUA.

Analyze DNA damage and protein impact

Damage to DNA (mutations) does not always result in damage or changes to the protein. Due to the redundancy of the genetic code (wobble effect), multiple codons can code for the same amino acid (silent mutations). Additionally, mutations can occur in non-coding regions of DNA (introns or intergenic regions) which do not affect the final protein sequence. Thus, the statement is False.

Identify the summary of the Central Dogma

The Central Dogma of molecular biology describes the flow of genetic information within a biological system. The standard flow of genetic information is from DNA (replication/transcription) to RNA (translation) to Proteins. Therefore, the correct summary is DNA - RNA - PROTEINS.

Answer:

Question 1

• CTA
• GAU
• CUA (Correct answer)
• CTT

Question 2

• True
• False (Correct answer)

Question 3

• PROTEINS - RNA - DNA
• RNA - DNA - PROTEINS
• DNA - RNA - PROTEINS (Correct answer)
• PROTEINS - DNA - RNA
