Answer:

Transcription makes RNA from DNA, translation turns RNA into proteins.

Explanation:

Transcription is the first stage in gene expression in which an RNA molecule is made by copying a gene's DNA sequence. Transcription is carried out by the enzyme RNA polymerase which joins nucleotides together to make an RNA strand, while translation is also a process in gene expression in which messenger RNA (mRNA) is decoded within a ribosome to build a chain of amino acids which later folds to form an active protein. Translation occurs after the process of transcription.

Different ratios occur in crosses with single gene pairs or two gene pairs. What types of ratios are likely to occur in crosses

likoan [24]

Answer:

Genotype ratio: 1, 1:1, 1:2:1

Phenotype ratio: 1, 3:1

Explanation:

Single gene pair cross is also known as monohybrid cross. This means that only one gene usually with two alleles is observed and it express one trait.

For example, if we name the gene for a certain trait with A, the possible genotypes are AA (dominant homozygous), aa (recessive homozygous) and Aa (heterozygous). Possible crosses are:

P: AA x AA

F1 : all of them are AA

The same is with aa x aa (all of the offspring are with aa genotype)

P: AA x Aa

F1: AA Aa AA Aa (genotype ratio 1:1) (phenotype ratio 3:1)

The same genotype ratio is in aa x Aa (offspring will have aa Aa aa Aa-(genotype ratio 1:1) (phenotype ratio 1:1)

P: Aa x Aa

F1: AA Aa Aa aa (genotype ratio 1:2:1) (phenotype ratio 3:1)

P: AA x aa

F1: Aa Aa Aa Aa (1)

Carmen's father gets a job working at a nuclear power plant in a nearby town. Carmen is initially very concerned. Which of Carme

Nikolay [14]

A nuclear power plant will use nuclear energy to power the town. While nuclear energy is perhaps one of the most effective ways to provide power, a nuclear accident is very dangerous, and could destroy an environment and its organisms. There was a nuclear accident in Chernobyl, Ukraine, in the 1900s. people had to evacuate because of it.
