Mitochondria contain their own genome and duplicate by fission. even so,Mitochondria cannot function for long when isolated from the rest of the cell because they are endosymbionts.

Organelles called mitochondria are focused on cellular respiration, which is how a cell gets its energy. Mitochondria and other organelles are found only in eukaryotic cells; they are absent in prokaryotes.

Endosymbiosis, in which one cell was swallowed by another and eventually started to function within it, is the theory put forth by scientists as to how mitochondria evolved. In exchange for other functions of metabolism, mitochondria produce energy in a symbiotic relationship with cells. Thus, mitochondria are dependent on their host cell for survival.

in the dna in chromatin, substitution mutations: a. are at a maximum in the nucleosomes b. are rarely seen, but deletion mutatio
Gelneren [198K]

In chromatin, substitution mutations are most common in linker regions. Option d is the correct answer.

Mutation by substitution When one nucleotide base is replaced by another, this occurs. Mismatch mutation A type of substitution mutation in which a single nucleotide is replaced, resulting in the coding of an incorrect amino acid, which usually results in a malfunctioning protein. Silent mutations are the result of genetic code redundancy (degeneracy): This is false, as silent mutations are the result of a base substitution that has no discernible effect on a protein's amino acid sequence.

you are studying a bacteria plasmid that contains 5 operons and 15 genes. how many transcriptional promoters are on this plasmid
mojhsa [17]

Numerous catabolic operons have their transcription controlled by glucose. The three enzymes needed for conversion are encoded by the operon's five structural genes.

<h3>How many genes are there in an operon?</h3>

Operons have a transcription promoter at the beginning, two to twelve genes on average, and a transcription terminator at the conclusion (Zheng et al. 2002; Lawrence 2003).

<h3>Yes, there is just one promoter for operons.</h3>

An operon is a group of genes that all use the same transcriptional promoter. Every operon contains regulatory DNA sequences that act as binding sites for regulatory proteins that either promote or inhibit transcription.

<h3>The promoter is a 3 or a 5?</h3>

An area of DNA known as a promoter is where RNA polymerase starts to transcribe a gene. Promoter sequences are often found directly in the genome.
