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...

4) Insulin protein - 51 amino acids. Find the number of nucleotides contained in the gene in which the insulin protein is programmed?
In genetic system of our organism, we have specifical coding, three nucleotides- forming 1 codon, which corresponds to the one aminoacid.So, 51*3= 153 nucleotides in the gene

Part III: Protein synthesis: Describe the role of each of the following in the process of protein synthesis v) Amino acids
Amino acids are structural units of all proteins. During protein synthesis, amino acids are attached to the appropriate tRNA molecule and are recruited to ribosomes. tRNA-amino acid complexes are bind...

Determine the amino acid sequence in the protein encoded in the following strand of DNA. ( You will need the codon chart found in the Genetics Unit) TAC AAG GCC TGG
Using the genetic code, it can be determined that TAC encodes tyrosine (Tyr), AAG - lysine (Lys), GCC - alanine (Ala), TGG - tryptophan (Trp). As a result, the amino...

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...

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...

There are 64 codons and 20 amino acids. Explain how these codons are used in encoding of amino acids
A codon is a sequence of three DNA or RNA nucleotides that corresponds with a specific amino acid or stop signal during protein synthesis. Of the 64 codons, 61 represent...
