Genetics - Organization and functions of genes
About the Lecture
The lecture Genetics - Organization and functions of genes by Jonathan Clark is from the course Biology: Basic. It contains the following chapters:
- Terms and Definitions
- DNA Replication and Protein Synthesis
- How Genes Act As Instructions
- Chromosomes of the Human Genome
- Summary
Included Quiz Questions
In DNA adenine always pairs with -
- thymine
- guanine
- another adenine
- amino acids
A single specific polypeptide chain is specifically coded for by a single
- gene
- amino acid
- protein
- ribosome
- rough E.R.
In DNA, guanine always pairs with
- cytosine
- adenine
- thymine
- amino acid
- ribose
DNA replication is called semi-conservative because -
- one strand from the original DNA double helix is conserved in each of the daughter double helixes
- it doesn't require any enzymes
- no strands from the original DNA double helix are conserved in either of the daughter double helixes
- it does require enzymes
- it takes place in the nucleus
A polypeptide chain is -
- a string of amino acids joined together by covalent bonds
- formed at the ribosomes
- coded for by the sequence of bases on an mRNA molecule
- a string of nucleic acids joined together by covalent bonds
- formed on the smooth E.R.
