If DNA sequence is 5' AATGCATCGCCCT 3' then when underlined strain is read 3' TTACGTAGCGGGA 5' mRNA will be AAUGCAUCGCCCU, where uracil is instead of thymine according to the complementary pairing. If we have m RNA sequence: 5'AUGCGCUAAUCGC 3', then due to the same rule of the complementary pairing we can predict the former DNA sequence: 5'TACGCGATTAGCG 3', where thymine is present instead of uracile. 3'ATGCGCTAATCGC 5'

Write the sequence of amino acids in a protein when the sequence of mRNA and the codon usage table are provided. Please give examples.

If we have mRNA sequence: AUGGCCUGACCAGGCUAG We can determine an amino acid sequence of a protein using genetic code:AUG GCC UGC CCA GGC UAG Met - Ala - Cys -...

a strand of DNA has 66 bases. how many amino acids will be in the protein that this strand codes for?

In exercise you have 66 bases (or 66/3=22 codons). One codon(3 bases) codes one amino acid. You have 22 codons and as a result protein will consist of 22 amino...

Template-dependent DNA synthesis takes place during DNA replication.what are the requirements for a DNA strand to act as template?

DNA strands may act as templates only during specialphase of cell cycle called S-phase, so cell should be in that phase of growth. To perform replication itself, a huge number...

Explain how the structure of each DNA template strand informs the structure of each newly replicated DNA strand

The sequence of nucleotides in the template DNA strand strictly determines the sequence of nucleotides in the replicated DNA strand. The rigor of the construction of the nucleotides of the...

what is the complementary DNA strand that is created from the template 3’ AACCAGAGTGGA during replication

The DNA complimentary strand will be 5' TTGGTCTCACCT 3'. The original strand runs from a 3' direction so that the complimentary strand will run from the 5' end direction.

The mRNA strand produced in the nucleus is complementary to the template strand of the DNA and a copy of the coding strand. Explain this:

The RNA product is complementary to the template strand and is almost identical to the other DNA strand, called the nontemplate (or coding) strand.If the gene that's transcribed encodes a...
