Biology RNA Problems Actual

A part of an mRNA molecule with the following sequence is being read by a ribosome: 5' CCG-ACG 3' (mRNA). The following charged transfer RNA molecules (with their anticodons shown in the 3' to 5' direction) are available. Two of them can correctly match the mRNA so that a dipeptide can form. The anticodon loop of the first tRNA that will complement this mRNA is

a. 3' GGC 5'

A particular triplet of bases in the template strand of DNA is 5' AGT 3'. The corresponding codon for the mRNA transcribed is

a. 3' UCA 5'

Given the locally unwound double strand above, in which direction does the RNA polymerase move?

a. 3' → 5' along the template strand

Given the locally unwound double strand in Figure 14.3, in which direction does the RNA polymerase move?

a. 3' → 5' along the template strand

According to Figure 13-3, which code specifies the same amino acid as UAU?

a. UAC

A part of an mRNA molecule with the following sequence is being read by a ribosome: 5' CCG-ACG 3' (mRNA). The following charged transfer RNA molecules (with their anticodons shown in the 3' to 5' direction) are available. Two of them can correctly match the mRNA so that a dipeptide can form. The dipeptide that will form will be

b. proline-threonine.

In Figure 13-3, which amino acid is specified by the mRNA code CCC?

d. Pro

What amino acid sequence will be generated, based on the following mRNA codon sequence? 5' AUG-UCU-UCG-UUA-UCC-UUG 3'

d. met-ser-ser-leu-ser-leu

A possible sequence of nucleotides in the template strand of DNA that would code for the polypeptide sequence phe-leu-ile-val would be

e. c. 3' AAA-GAA-TAA-CAA 5'
