Q: Explain How Protein Synthesis Can Be Controlled At A Transcriptional Level In Prokaryotes
In prokaryotes, genes that encode enzymes of a metabolic pathway are usually clustered together on the chromosome in a region called an operon. A typical operon consists of regulatory sequences, like promoter, operator, terminator, and structural genes....

Allele Vs. Gene
How are alleles and genes different? And how do they correspond with each other? Alleles are pairs of genes and help code for an organism. Genes come from the parent organisms in order to help with the make up of an organism. There are...

The Chloroplast Genome Codes For Many Proteins And Rnas
KEY CONCEPTS:Chloroplast genomes vary in size, but are large enough to code for 50-100 proteins as well as the rRNAs and tRNAs. What genes are carried by chloroplasts? Chloroplast DNAs vary in length from 120-190 kb. The sequenced chloroplast genomes...

How Many Genes Are Expressed?
KEY TERMS:The transcriptome is the complete set of RNAs present in a cell, tissue, or organism. Its complexity is due mostly to mRNAs, but it also includes noncoding RNAs. Housekeeping genes (Constitutive gene) are those (theoretically) expressed...

The Content Of The Genome
KEY TERMS:The genome is the complete set of sequences in the genetic material of an organism. It includes the sequence of each chromosome plus any DNA in organelles. The transcriptome is the complete set of RNAs present in a cell, tissue, or organism....
