If you are studying a gene within DNA and find out that guanine makes up 41% of it, how much is Adenine?
There are four bases found in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). Adenine forms a base pair with thymine, and cytosine forms a base pair with guanine. There is a one-to-one relationship in these base pairings (Chargaff’s rule), which means that if you know the percentage of any one of them within a given DNA sample, you can calculate the percentages of the other three. In this case, you're given the percentage of guanine, and you want to find out the percentage of adenine.
Since guanine base-pairs with cytosine and since there must be as much cytosine as there is guanine, 41% of the bases in this gene are cytosine as well. That means that adenine and thymine together make up the remaining 18% (100% − 41% G − 41% C) of the base pairs. If there must be an equivalence in the number of thymine and adenine bases per Chargaff's rule, then half of the remaining base pairs must comprise adenine and the other half comprise thymine. Half of 18% is 9%.
Thus, adenine makes up 9% of the bases in this gene.
Why do individuals with recessive
traits show up with less frequency
in populations?
A. There are more dominant alleles in most
populations.
B. Individuals must inherit two copies of a
recessive allele to show the trait.
C. Recessive traits greatly outnumber dominant
traits in most populations.
The individuals with recessive traits show up with less frequency in populations because the individuals must inherit two copies of a recessive allele to show the trait.
What is an allele?"They are the alternative forms of a gene."
What is a recessive trait?It is a trait that is expressed only when the both alleles in the genotype are recessive.The genotype should be homozygous recessive for the trait to appear.What is a dominant trait?A dominant trait is a trait that is expressed even when one parent contributes the dominant allele.It is expressed when the genotype is heterozygous dominant or homozygous dominant.To learn more about recessive, dominant, and populations here,

Transcribe and translate the following DNA strand into an RNA strand: TACCA
GTAGATT
Answer:
Explanation:Key points:
Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.
Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).
Transcription has three stages: initiation, elongation, and termination.
In eukaryotes, RNA molecules must be processed after transcription: they are spliced and have a 5' cap and poly-A tail put on their ends.
Transcription is controlled separately for each gene in your genome.
Introduction
Have you ever had to transcribe something? Maybe someone left a message on your voicemail, and you had to write it down on paper. Or maybe you took notes in class, then rewrote them neatly to help you review.
As these examples show, transcription is a process in which information is rewritten. Transcription is something we do in our everyday lives, and it's also something our cells must do, in a more specialized and narrowly defined way. In biology, transcription is the process of copying out the DNA sequence of a gene in the similar alphabet of RNA.
Overview of transcription
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.
In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.
Example:
Coding strand: 5'-ATGATCTCGTAA-3'
Template strand: 3'-TACTAGAGCATT-5'
RNA transcript: 5'-AUGAUCUCGUAA-3'
For a protein-coding gene, the RNA transcript contains the information needed to synthesize a polypeptide (protein or protein subunit) with a particular amino acid sequence. In this case:
RNA transcript (acting as messenger RNA): 5'-AUGAUCUCGUAA-3'
Polypeptide: Met-Ile-Ser-STOP
In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.
Example:
Coding strand: 5'-ATGATCTCGTAA-3' Template strand: 3'-TACTAGAGCATT-5' RNA transcript: 5'-AUGAUCUCGUAA-3'
For a protein-coding gene, the RNA transcript contains the information needed to synthesize a polypeptide (protein or protein subunit) with a particular amino acid sequence. In this case:
RNA transcript (acting as messenger RNA): 5'-AUGAUCUCGUAA-3' Polypeptide: Met-Ile-Ser-STOP
RNA polymerase
The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.
RNA polymerase synthesizes an RNA strand complementary to a template DNA strand. It synthesizes the RNA strand in the 5' to 3' direction, while reading the template DNA strand in the 3' to 5' direction. The template DNA strand and RNA strand are antiparallel.
RNA transcript: 5'-UGGUAGU...-3' (dots indicate where nucleotides are still being added at 3' end)
DNA template: 3'-ACCATCAGTC-5'

RNA transcript: 5'-UGGUAGU...-3' (dots indicate where nucleotides are still being added at 3' end) DNA template: 3'-ACCATCAGTC-5'
Stages of transcription
Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria. You can learn more about the details of each stage (and about how eukaryotic transcription is different) in the stages of transcription article.
Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription.

The processes of diffusion and active transport are both used to * break down molecules to release energy move molecules into or out of cells of the body bring molecules into cells when they are more concentrated outside of the cell move molecules against a concentration gradient, using ATP molecules
Answer:
move molecules into or out of cells of the body
Explanation:
Majorly, there are two types of transport used by living cells. These are; passive and active transport. Passive transport involves the movement of molecules down a concentration gradient without the need for energy (ATP) input. Example is DIFFUSION AND OSMOSIS.
On the other hand, active transport is a type of transport that moves molecules against a concentration gradient (low to high) with the aid of energy input (ATP). Example is sodium-pottasium proton pump.
Although there are obvious differences between these two processes (diffusion and active transport), but they both MOVE MOLECULES INTO OR OUT OF CELLS OF THE BODY.
