Definitions/Explanation : Heterochromatin & Semiconservative $DNA$ replication
$(1)$ The chromatin that is more densely packed and stained dark are called Heterochromatin. It is inactive.
$(2)$ The two of $DNA$ strands would separate and act as a template for the synthesis of new complementary strands. After the completion of replication, each $DNA$ molecule would have one parental and one newly synthesized strand. This scheme was termed as semiconservative $DNA$ replication.
Which of the following statement is incorrect?
$A$ : Polypeptide sequences are dictated by $DNA$ and represented by $mRNA$.
$R$ : Sequence of amino acids in a polypeptide can be predicted by the exact sequence of nucleotides on the $mRNA$ and template $DNA$
Consider the following
1.Structural gene
2.Messenger $RNA$
3.Ribosomes
4.Transcription
5.Translation
Which of the following is the correct sequence for protein synthesis
Assertion : Replication and transcription occur in the nucleus but translation in the cytoplasm.
Reason : $m-RNA$ is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.
Briefly describe the following:
$(a)$ Transcription
$(b)$ Polymorphism
$(c)$ Translation
$(d)$ Bioinformatics
