Question

Why is "semiconservative" an appropriate description for the DNA replication process? What is the product of transcription? What is the function of this molecule? List the three types of RNA and their functions. Which one of these do you think will be broken down in a short time? a. Which codon will you always find at the beginning of an mRNA encoding a polypeptide? b. What are the nucleotides that you will find at the end of an mRNA encoding a polypeptide sequence? What is the source of free amino acids in the cytoplasm? List order of size the following gene, cell, ohromosome, atom, nucleus, base subunit, nucleotides. What could be consequence of deletion or duplication of gene sequence on protein sequences?

Explanation / Answer

3: Which nucleotides bond to which nucleotids?How?

Purines bond with pyramidines in both RNA and DNA.

In DNA Adenine and Thymine bond together by two hydrogen bonds while in RNA Thymine is replaced by Uracil and adenine bonds with uracil by two hydrogen bonds.In both DNA and RNA Guanine bonds with cytosine by means of three hydrogen bonds

4.The two strands of DNA are described as antiparallel because the head of one strand is always laid against the tail of the other strand of DNA.i.e  At each end of the double helix, one strand is 5' and the other is 3'.
