Question

Please help!!
Create three relevant questions that you would like answered or clarified about the role of
DNA and chromosomes. Focus on the following areas as you generate questions:
i. The cause and effect relationship between the genetic code and gene expression
ii. Mechanisms of gene regulation
iii. The role of DNA segments that do not code for proteins

Answer 1

Answer:

1) How is DNA compacted to form a chromosome?

2) How to cells undergo differentiation to form the numerous types of cells in the body?

3) What are some functions for non-coding DNA [e.g. Centromere, telomere, promoter, terminator, silencer, enhancer, introns (alternative splicing)]

Explanation:

1) involves packing of DNA that involves DNA associating with H1, H2a, H2b, H3, H4 histone, scaffolding proteins and link genes)

2) since all somatic cells are genetically identical, differentiation involves silencing certain genes through different chemical signals that the stem cell's environment is in, resulting in certain genes related to its function being expressed while other genes are silenced.

3) non coding sequences although the bulk of DNA, has numerous importsnt roles. ( centromere allow for association of kinetochore proteins to form kinetochore that acts as site of attachment for microfibrils during mitosis or meiosis) (telomere act as sacrificial DNA that prevents erosion of Coding DNA during every round of semi-conservative DNA replication)...

Answer 2

Answer:

Question 1-  who 64 codon is responsible for the formation of all types of protein? who a codon expresses itself to form an amino acid?

Question 2- what is lac operon?

Question 3 - what are the exon and intros in the Hnrna and what are their functions?

Explanation:

Answer 1-  A codon is a group is three nitrogenous bases that together code a specific amino acid.  These base pairs arrange themselves in a new order to code for a new amino acid.

Answer 2-  Lac operon is a regulation unit present in the nucleus, which helps in the regulation of the formation of the protein in the presence of the inducer unit.

Answer 3- exons and introns are the codings and non-coding sequences of the DNA respectively. These introns are removed under the modification setup so that Rna can make protein without any hindrance.
