Which type of genetic exchange occurs among bacteria in which dna is carried into a bacterial cell by means of a virus?

Answers

Answer 1

Answer:

Transduction

Explanation:

Among the three types of gene transfer in bacteria, transduction does not require physical contact between the two bacteria cell. Viruses that infect bacteria accidentally move pieces of chromosomal DNA from one bacterium to another. These viruses that infects bacteria are called bacteriophages.

Simply put, transduction is a process of genetic recombination in bacteria which involves the incorporation of the genes of a host cell (bacterium) into the genome of a viral cell (bacteriophage) and then conveyed to another host cell when the bacteriophage infects it. The process of transduction is of two types; generalized and specific depending on whether any gene or specific gene is transduced respectively.

The aim of these viruses when they infect bacteria cell is to harness the ability of bacteria to replicate, transcribe and translate their genetic material and use it to procreate into many virons or complete their viral particle.

For any given gene, what ultimately determines which dna strand serves as the template strand?

Answers

The answer is the base sequence of gene's promoter.

DNA is a two-stranded helix. One strand is called a template strand, the other one is called a coding strand. The template strand is copied into mRNA, and the coding strand is complementary to the template strand. RNA polymerase, an enzyme responsible for transcription, has to recognize the right strand before transcription begins. So, it recognizes one or more short sequences on the coding strand. This is the base sequence of gene's promoter. Thus, the complementary strand is the template strand.

1.If you cross two pea plants that are heterozygous for flower color (Pp), what is the percent chance that the offspring will be white? 2.Round peas (R) are dominant to wrinkled peas (r). If a pea plant with the genotype Rr is crossed with a pea plant with wrinkled peas, what are the odds that the offspring will have wrinkled peas?

Answers

The principle of dominance. The gene for purple flowers is dominant, while the gene for white flowers is recessive. We know this because both flowers are homozygous, meaning their genes are the same

1. There is a 25% chance that the flowers will be white.

2. There is a 50% chance that the peas will be wrinkled.
