Recombination occurs during _____.

Biology
2 answers:
slavikrds [6]3 years ago

Answer:

The correct answer would be meiosis.

During meiosis, recombination takes place in the form of crossing over.

It is an event that takes place during the pachytene stage of prophase I of meiosis I.

During this event, the genetic material gets exchanged between non-sister chromatids of homologous chromosomes.

It results in the production of new combinations of genes which are not present in either parent and thus, results in the genetic variation in a population.

yulyashka [42]

Answer:

B. The mutation results in a new, dominant allele

C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.

D. The mutation occurs in a codon and alters the function of the final protein

Explanation:

All the above things will change the <u>ultimate expression</u> or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.

Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.

This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.

Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.

Identify the evolutionary forces that can cause allele frequencies to change from one generation to the next.
Irina-Kira [14]

<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.

Anit [1.1K]

Answer: DNA ligase.

Explanation:

Polymerase chain reaction is a technique used in molecular biology by scientists to make several copies of a DNA sample which enable them to take a smaller portions of it and expand it for more detailed study.

PCR mixture is premixed and contain thermostable DNA polymerase, oligonucleotides primer, four deoxynucleodide triphosphates, Magnesium chlorides, a propietary buffer.
