Genes and Chromosomes

Question 1

What is a gene?

Genes and Chromosomes

Answer 1

A sequences of DNA babes that codes for either a polypeptide or functional RNA

Question 2

What is the genome?

Answer 2

All genetic material in an organism or cell

Question 3

What is a proteome?

Genes and Chromosomes

Answer 3

The full range of proteins an organism (or cell) is able to produce

Question 4

What is an intron?

Genes and Chromosomes

Answer 4

Sections of DNA in eukaryotes that don’t code for polypedtides of functional RNA
Introns are removed in protein synthsis
Prokaryotic DNA has no introns

Question 5

What is an allele?

Genes and Chromosomes

Answer 5

One or more alternative versions of the same gene

Question 6

What are homologus chromosomes?

Genes and Chromosomes

Answer 6

Humans have 23 pairs of chromosomes
The pairs of matching chromosomes are homologus pairs
In a homologus pair both chromosomes are same size and have same genes but could have diff alleles
Alleles coding for same characteristic are found in same locus on each chromosome in the pair
