amid [387]

Answer:

C) A changed to G in the first position of the codon.

Explanation:

In the translation of DNA,  triplets  or codons of mRNA  (a group of three nucleotides) are read according to a genetic code, to build proteins.

Proteins are composed of amino acids. In the translation process, each codon codes for an particular amino acid according to the  genetic code as illustrated  in the DNA codon table (attached here).  

In this table we can see that if the first position  of any of the codons coding for Threonine ( ACT, ACC, ACA, ACG) is changed for G, Adenine is going to be encoded instead of threonine.

If the nucleotides 5'-GAT-3' are paired with the nucleotides 3'-CUA-5', the pairing must be __________.
arlik [135]

Answer:

The correct answer is A.) during transcription

Explanation:

The pairing during DNA replication and transcription is a little bit different. During replication, A pairs with T, T with A, C with G, and G with C. In transcription T is replaced by U so when there is nucleotide adenine is present in the DNA sequence than uracil will be added against it as complementary nucleotide in mRNA during transcription.

So here 5'-GAT-3' nucleotide sequence is present in DNA and after transcription the nucleotide sequence will be 5'-CUA-5' because U is added against A during transcription. Therefore the correct answer is A.

If you block histone deacetylase, what effect would you expect to see on transcriptional activity?.
Shalnov [3]
Histone deacetylase is responsible for removing the acetyl group from the histone 3 lysine 9 residue. Remember that deacetylation is one step in converting euchromatin to heterochromatin. Because euchromatin is transcriptionally active (transcriptional machinery is able to reach gene of interest), and blocking histone deacetylase activity would result in an the DNA remaining as euchromatin, we would expect to see an increase in transcriptional activity.

So there’s your answer: An increase in transcriptional activity.
