QUESTION 10

1. Which of the following is the term used to describe the DNA strand that is to be READ by the RNA Polymerase for transcription (the strand that functions as the blueprint)?

	a.	lagging strand
	b.	leading strand
	c.	template strand

Answer 1

1- (c). During replication unwinding of the parental DNA duplex is occurs first, it is done by enzyme DNA Helicase. After that the rest of the options given occurs.

2- (d). A gene can be defined as "a segment of DNA that encodes for _protein_

3- (c). The mode of information transfer does not occur in the real world is direct DNA to protein.

4- (e). mRNA serves as the template for Translation.

5- (e). The replication of DNA occurs in the nucleus. Note*- in eukaryotes DNA replication occurs in nucleus. But as in prokaryotes lack nucleus DNA replication occurs in cytoplasm. As here not mentioned whether the cell is eukaryotic or prokaryotic. I prefer here the cell is eukaryotic so I choosed the option nucleus.

6- (d) One strand of the DNA serve as the template for transcription.

7-(c) Apparently our muscle cells are different from our nerve cells mainly because the cell express different gene.

8-(a) the product of DNA Replication is double stranded DNA. Note* there are also having single Stranded DNA in many species. In those species the product of DNA replication is single stranded DNA.

9-(d) transcription and then translation occurs.

10-(c) the term used to describe the DNA strand that is to be READ by the RNA Polymerase for transcription is template strand.
