Refer back to Figure 21.8 for a description of many clones to the procedure.
A large number was produced.
The types of genes in the genome are explored.
The H. influenzae has a genome size of 1.83 MB.
Many of the genes could be compared to genes in other species.
1,743 genes were predicted by the computer analysis.
There are different categories based on their predicted function in the complete set of vectors.
The total number of genes they were able to sequence was approximately 10.8 billion.
What was the goal of the investigation conducted by Venter?
Let's suppose that researchers used a computer to get information about the DNA sequencing approach and then used the shotgun the genome sequence to sequence a bacterium with a genome size of 4.1 billionths of a second.
The goals and results of the Human Genome Project are listed.
We looked at the genomes ofbacteria and archaealbacteria in the previous section.
Eukaryotes include protists, fungi, animals, and plants.
You will learn that their genomes are larger.
The genomes of important agricultural species can be difficult to sequence.
The development of new strains of livestock and plant species will be examined to see how the duplication of genes can lead to improved traits.
The goal of the Genome Project was to map and sequence the way to establish evolutionary relationships.
One set contains sources in humans.
It is easier for Y because of the availability of genome sequences.
The genome size is the number of megabase pairs in one set of chromosomes.
Both sex chromosomes are included for species with sex chromosomes.
The genome is involved in photosynthesis.
The nuclear genome is located in the cell nucleus, but the elles of the genome are located in the mitochondria.
We will focus on the nuclear genome in this chapter.
In the past decade or so, the entire nuclear genomes of hundreds of species have been determined.
There are mammals in Table 21.4.
The amount of DNA is measured in megabase pairs.
The size of the genome is shown on a log scale.
Major variations in genome sizes are observed in related species of globe thistle.
These species are similar in form and function.
As an example, let's look at two accumulation of repetitive genes.
There are many copies of the short DNA sequence in chapter 21.
There are a lot of repetitive sequences in spe crossover.
We will look at the characteristics of the repetitive sequence, one with a deletion of a genes and two normal chromosomes.
If a haploid cell carrying the chromosomes with the duplicated genes participates in fertilization with another gamete, an offspring with a duplicated genes is produced.
Gene duplications can be transmitted to future generations in this way.
Gene duplications can happen several times during evolution.
A group of paralogs carry out func tions.
In Let's now turn our attention to gene duplications, a way of animals, the globin gene family is an example.
The number of genes in a genome can be increased by the globin genes.
There are genes that function in oxygen binding.
Hemoglobin is a red blood cell that carries oxygen throughout the body.
Each version of the gene accumulates different globin genes between 500 and 600 mya, according to an evolutionary analysis.
Since that time, there have been additional duplication events and chromosomal rearrangements.
There are two copies of the same gene.
Over time, these copies accumulate different random mutations, which results in different genes.
If two chromosomes don't match up, there is a chance that one of them will have a gene duplication.
A single ancestral globin genes evolved into the globin gene family.
