Question

question 18
what is the main goal of the central dogma?
to create proteins to carry on body functions
to create dna to carry on body functions.
to create rnas to carry on body functions.
to create a catchy song to carry on body functions.

question 19
if the dna sequence is tac ttg acc, what would be the resulting amino acid sequence after transcription and translation?
(hint: think of the first step of protein synthesis? do this first and then find the amino acid sequence.)

Explanation:

Question 18

The central dogma of molecular biology describes the flow of genetic information. DNA is transcribed to RNA, and RNA is translated to proteins. Proteins are the molecules that carry out most of the body's functions. DNA is the genetic material that stores information, not created for body functions in this context. RNA is an intermediate, not the final functional molecule for most body functions. A song is irrelevant to biological processes.

Step1: Transcription

DNA sequence: TAC TTG ACC
mRNA is complementary to DNA (A - U, T - A, C - G, G - C). So mRNA sequence: AUG AAC UGG

Step2: Translation

Using the codon table:
AUG = met (start codon), AAC = asn, UGG = trp

Answer:

A. To create proteins to carry on body functions
