The strand of mRNA that has the bases "CCU" corresponds to the DNA template strand that would have the complementary bases "GGA." In the context of protein synthesis, "CCU" codes for the amino acid proline in the genetic code. Thus, this specific mRNA sequence plays a crucial role in the translation process during protein synthesis.
To determine the tRNA that corresponds to the coding DNA strand "atgcca," we first need to transcribe it into mRNA by replacing thymine (T) with uracil (U). The mRNA sequence would be "augccu." The tRNA anticodons that pair with the mRNA codons would be "uac" (for AUG) and "agg" (for CCU). Therefore, the tRNA molecules would carry the amino acids methionine (for AUG) and glycine (for CCU).
codon
A codon is a 3-base long sequence. Therefore the first codon in CCU-AGA-AUU- GGC-C is CCU. CCU codes for the amino acid Proline.
MRNA
DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.
There would be 393 bases on the mRNA strand corresponding to 131 amino acids, as each amino acid is coded for by a sequence of three bases (1 codon). By multiplying the number of amino acids by 3, you can determine the total number of bases required to encode the protein sequence on mRNA.

DNA is not made into mRNA, it is transcribed by mRNA. The DNA molecule is split into two strands by the enzyme helicase. One strand is the sense strand and the other is the anti-sense strand. Then mRNA nucleotides pair with their complimentary DNA bases on the antisense strand. The enzyme RNA polymerase causes the mRNA nucleotides to bond with one another, forming a strand of mRNA.
The corresponding mRNA strand would be AUCG.
mRNA is like a single strand instead of a double strand. If DNA is like a twisted ladder, then mRNA is like a single half of that ladder, with only half the bases.
To determine the base sequence of a DNA strand from a given mRNA sequence, you need to consider that mRNA is synthesized from the DNA template strand through a process called transcription. The mRNA bases pair with their complementary DNA bases, where adenine (A) pairs with thymine (T), uracil (U) in mRNA pairs with adenine (A) in DNA, cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). Therefore, to find the DNA base sequence, you can convert the mRNA sequence to its corresponding DNA sequence by replacing U with A and reversing the order to get the complementary DNA strand.
