Answer:
Sperm and egg have 23 the number of chromosomes as a body cell.
Hope this helps =)
Answer:
<u>Part A</u>
Drag these words to the space
(1) tRNA: "contains an anticodon" "has amino acids covalently attached in active form"
(2) mRNA: "has introns and exons" "contains genes for a protein"
(3) rRNA: "is found in ribosomes" "is the most abundant form of RNA"
<u>Part B</u>
(1) Replication: Leave blank because no RNA is involved
.
(2) Transcription/RNA processing: mRNA because it is synthesized from the information in DNA
(3) Translation: rRNA and tRNA
A change that occurs in muscles at the anaerobic threshold is that the body begins to convert to fermentation instead of the Krebs Cycle.
Answer/Explanation:
A mutation alters the sequence of DNA. Therefore, the mRNA that is transcribed from the DNA has a different sequence.
This mRNA goes on to be read by the protein synthesis machinery in the cell. The protein synthesis machinery translates the sequence of the mRNA into an amino acid sequence, which makes up the protein.
If the sequence of the mRNA is different, due to a mutation in the DNA, then the cell will translate a different sequence into an amino acid. This alters the composition of the protein.
Mutations can be small, and affect only one amino acid, or they could be huge, and impact the entire protein.
Mutations have very different consequences in gametes vs non-gamete cells.
If a mutation occurs in a gamete, that means the mutation will be passed on to the next generation, as it is contained in the DNA in the egg or sperm that becomes fertilised to make a gamete.
However, mutations that occur in other cells are not passed on to the next generation. That does not mean they do not have effects. E.g. mutations in the skin caused by exposure to UV rays from the sun can contribute to cancer, but would not be passed on to the individual's children
