What is a mutation?
What effects can mutations have on an organism?
Are most mutations harmful or harmless?
thanks!!
Answer:
Mutations are when the RNA makes a mistake copying the DNA and causes genes to 'accidentally' change.
Mutations can do anything from accidentally changing hair or skin color to causing dangerous diseases.
Only a small percentage of mutations cause genetic diseases. Most of them are harmless.
Blood type is controlled by the inheritance of any two of the following alleles: IA, IB, or i. IA codes for type A blood. IB codes for Type B blood. Both IA and IB are codominant. The i allele is recessive and will cause Type O blood whenever two copies of the allele are present.
If a mother has Type AB blood (IAIB) and a father has Type O blood (ii), what percentage of their children are likely to have Type A blood?
A. 25%
B. 50%
C. 100%
D. 0%
Answer:
B
Explanation:
A sequence of a DNA template strand is shown below.
3’ T C C A A T G G C T T A T T T G C A 5’
Which of these is the correct amino acid chain produced from the DNA template strand?
Arginine – Leucine - Proline – Asparagine – Lysine – Arginine
Serine - Leucine – Proline – Asparagine – Lysine – Arginine
Tryptophan – Phenylalanine – Leucine – Glycine – Asparagine – Phenylalanine
Tryptophan – Phenylalanine – Leucine – Glycine – Asparagine - Serine
The correct amino acid chain produced from the DNA template strand will be Arginine – Leucine - Proline – Asparagine – Lysine – Arginine. The correct option is A.
What is amino acid?Amino acids are molecules that form proteins when they combine. The building blocks of life are amino acids and proteins.
Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.
A codon is a three-nucleotide (DNA or RNA) sequence that forms a unit of genomic information encoding a specific amino acid or signaling the end of protein synthesis (stop signals).
There are 64 different codons, 61 of which specify amino acids and three of which serve as stop signals.
The amino acid sequence for the given template will be:
3' AGGUUACCGAAUAAACGU 5'
So, as per three letter code, the amino acid chain will be:
Arginine – Leucine - Proline – Asparagine – Lysine – Arginine
Thus, the correct option is A.

In the cochlea: A. sight occurs B. the visual image is projected O C. sound vibrations are converted to nerve impulses O D. sound is made either louder or softer
Answer:
C, is the answer
Explanation:
Option C. sound vibrations are converted to nerve impulses.
What is in the cochlea?The cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact, takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turn around a hollow central pillar, the modiolus.
What is the main function of the cochlea?The cochlea is a hollow, spiral-shaped bone found in the inner ear that plays a key role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the brain can interpret as individual frequencies of sound.

New seed does not germinate in spite of suitable environment Why?
Answer:
All seeds do not germinate to form new plant because some are not fulfilled with the appropriate amount of nutrients.
Explanation:
A new seed does not germinate in spite of a suitable environment due to a lack of enough nutrients in the soil, a seed may undergo the dormant stage, and too much or little water in the soil.
What is Germination?Germination may be defined as a process through which a seed grows into a seedling.
A lack of nutrients does not deliver enough energy to seed for germination. If the soil has too little water or no water, a seed remains dormant throughout, while if it has too high water, then the seed becomes susceptible to infections.
Under all the above conditions, a seed will germinate into a seedling in spite of a suitable environment.
Therefore, it is well described above.

____________ polymerase is used to add new RNA nucleotides to make RNA.
RNA polymerase is used to add new RNA nucleotides to produce RNA.
RNA polymeraseIt is the enzyme responsible for copying the sequence of DNA into the sequence of RNA during the process of transcription.
The information encoded in DNA is used to produce RNA during the process of transcription.
The production of RNA takes place by the enzyme RNA polymerase, by using the antisense strand of the DNA as the template by supplementing the complementary RNA nucleotides to the 3 prime terminal of the developing strand.
The enzyme RNA polymerase combines with the DNA at a sequence known as the promoter at the time of the beginning of transcription.
Thus, the given blank can be filled with RNA.

If the DNA sequence is --- AAA TAT CCG TAG CAA ATG, write the mRNA sequence, tRNA anticodon sequence, and the six amino acids for this.
adenine(A) binds with uracil(U)
Thymine(T) binds with Adenine(A)
guanine(G) binds with cytosine(C)
The complementary mRNA, which contains the codons is
UUU AUA GGC AUC GUU UAC
The complementary tRNa , which contains the anticodons is
AAA UAU CCG UAG CAA AUG
The six aminoacids are
phenylalanine-isoleucine-glycine-isoleucine-valine-tyrosine
The bases tend to exist as a pair in the DNA’s double helix structure. The bases are bonded by hydrogen bonds.
Their bonds are mentioned as follows:
Adenosine (A) is paired with thymine (T) Cytosine (C) is paired with guanine (G)However, the base thymine (T) is present only in the nucleotide of DNA and the base uracil (U) is present only in the nucleotide of RNA.
