The nucleotide sequence on a section of
DNA where transcription begins is called a promoter.
To add, i genetics, a promoter is a region
of DNA that initiates transcription of a particular gene. Promoters are found along
the transcription beginning sites of genes, on the same strand and upstream on
the <span>DNA.</span>
b) A population first divided into two parts, then three parts, and then four parts, until a description identifies a single member.

Carbon is found in the non-living part of the hydrosphere, atmosphere, and Geo-sphere, as carbonate (CaCO3) rocks and dead organic matter, such as humus in soil.
Answer:
Build homes and stable environments for people to live in during the bad weather.
<u> Allele frequencies to change from one generation to the next.-</u>
<u>B. </u><u>Mutation</u><u>; C. Random genetic drift; D. </u><u>Migration</u><u>; F. Natural selection</u>
- Selection, mutation, migration, and genetic drift are the mechanisms that effect changes in allele frequencies.
- When one or more of these forces are acting, the population violates Hardy-Weinberg assumptions, and evolution occurs.
Why do allele frequencies change from one generation to the next?
Random selection: Allele frequencies may fluctuate from one generation to the next when people with particular genotypes outlive those with different genotypes.
No mutation: Allele frequencies may fluctuate from one generation to the next if new alleles are produced via mutation or if alleles mutate at different rates.
What are 5 factors that cause changes in allele frequency?
- A population, a collection of interacting individuals of a single species, exhibits a change in allele frequency from one generation to the next due to five main processes.
- These include natural selection, gene flow, genetic drift, and mutation.
