Which statement best explains how the genetic code is universal? * The shape of a DNA molecule is the same in different species.

AysviL [449]

Answer:

A DNA sequence codes for the same proteins in different species

Explanation:

All living organisms store their genetic information in DNA (genetic material). The manner through which information in the genes are encoded is the GENETIC CODE. The genetic code comprises of all the codons that specifies amino acids in living organisms. The genetic code has several characteristics, which includes that the GENETIC CODE IS UNIVERSAL

The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.

Identify the evolutionary forces that can cause allele frequencies to change from one generation to the next.

Irina-Kira [14]

Allele frequencies to change from one generation to the next.-

B. Mutation; C. Random genetic drift; D. Migration; F. Natural selection

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.

The surface area to volume ratio limits a cell

svetlana [45]

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.
